This land is ancestral and unceded land of the Chepenafa (Mary’s River) Band of the Kalapuya (pronounce “cal-uh-poo-yuh”), who have stewarded this beautiful area for generations. The descendants of the Kalapuya People are now part of the federally recognized Confederated Tribes of Grand Ronde and Confederated Tribes of the Siletz of Oregon. The peak you see from numerous vantage points around Corvallis is Mary’s Peak, which the Kalapuya called tcha Timanwi, or ‘place of spiritual power’, and is the highest peak in the Oregon Coast Range (4,097 feet).

Key Concepts Across Both languages

Core Libraries

• Spatial data structures across languages and applications is primarily organized through OSgeo and OGC) and a few core libraries underpin spatial libraries in programming languages and in software applications(R, Python, QGIS, ArcPro)!

These libraries include:

• PROJ –> Spatial projections, transformations

• GEOS –> Geometry operations (measures, relations)

• GDAL –> Raster and feature abstraction and processing (read, write)

• NetCDF –> Multidimensional (XYZT) data abstraction (read, write)

Web Services

More and more data is available as web services, and the data is stored in a remote server in JSON, XML, HTML format which is accessible through API’s.

JSON (JavaScript Object Notation) is a lightweight data-interchange format which is easy for machines to generate and parse; easy for humans to write and read.

Sample JSON format : { “data”: “Click Here”, “size”: 36, “style”: “bold”, “name”: “text1”, }

API - An Application Programming Interface (API) takes a structured request from an application and returns structured results from the host application. With a Rest API you’re getting a representation of the requested data stored in a server. A Rest API also is what we call ‘stateless’, which means a server doesn’t store any data between requests from clients.

Rest APIs access data through uniform resource identifiers (URIs), which are essentially a string of characters that identify a specific resource. The type of URI used by a Rest API is a uniform resource locator (URL).

HTTP clients are used for accessing the API. HyperText Transfer Protocol (HTTP) enables communication between the client and server using HTTP methods. If we want to access or manipulate resources a Rest API uses specific request verbs we need to become familiar with:

• GET: used to acquire data from a database

• POST: used to add data to a database

• PUT: update the data in a database

• DELETE: delete data in a database

Although web services facilitate accessing various datasets, we have to be wary of their limitations. Creating and maintaining a web service is a technically challenging and involved task, and it becomes even more complicated when the service becomes public. For public web services, number of users and load of their request is not predictable. Thus, public web services often have limitations and quotas on the number of requests. Considering that there are workarounds for these limitations, some users, wittingly or unwittingly, can cause a web service to slowdown or even shut down. So, we should expect planned or unplanned downtimes when using web services. Planned downtimes are usually announced by the service provider that can be for maintenance purposes or making some changes to the service. Keeping up with these changes is also another aspect that we need to take into account when working with web service.

Additionally, sending a request and retrieving a response from a web service (a web service call) has an inherent overhead and is much slower than accessing a local file. Thus, web services might not be suitable for “large” requests, and it might be more efficient to download the dataset and store it locally. How “large” is large, depends on the capacity of a web service and the complexity of the request. For example, the NLDI web service has an endpoint that can navigate the NHD network up or downstream of a point of interest up to a given distance. This call is computationally expensive thus making many such requests can impact the performance of the web service. For such cases, it is more efficient to download the NHDPlus dataset and perform the navigation locally. For example, NHDPlusTools in R and PyNHD in Python provide tools to navigate the NHDPlus dataset locally.

By in large, web data access will fall into three broad categories.

1. APIs,
2. Object Stores, and
3. File Servers.

APIs

When working with an API, you are interacting with a remote computer that may or may not be prepared to cope with many concurrent requests. The computer may have less compute power than your laptop and it may be connected to an inexpensive storage device that can only provide a few MB/s of throughput. When working with APIs, you should always:

1. start small and check latency per request.
2. scale up request size and check response time scaling.
3. increase parallelism slowly and check response performance.

The code below demonstrates this using requests to a geospatial web service.

Code

point <- sf::st_sfc(sf::st_point(c(-76.61612, 39.23875)), crs = 4326)
# just baseline request time
start_comid <- nhdplusTools::discover_nhdplus_id(point)
upstream_comid <- dataRetrieval::findNLDI(start_comid, nav = "UT", distance_km = 999)
comids <- as.integer(upstream_comid$UT_flowlines$nhdplus_comid)
sf::sf_use_s2(FALSE) # hides warnings
# first, just check per request timing.
# if we had a lot to run, simple match will tell us how long to expect.
system.time(nhdplusTools::subset_nhdplus(comids[2], 
                                         nhdplus_data = "download", 
                                         status = FALSE))
# Now try scaling up.
system.time(nhdplusTools::subset_nhdplus(comids[1:100], 
                                         nhdplus_data = "download", 
                                         status = FALSE))
# scale up further and observe timing
system.time(nhdplusTools::subset_nhdplus(comids[1:400], 
                                         nhdplus_data = "download", 
                                         status = FALSE))
# we can experiment with parallelism
future::plan(future::multisession, workers = 2)
future::future(sf::sf_use_s2(FALSE))
# run in two chunks and two workers
system.time(future.apply::future_lapply(list(comids[1:200], comids[201:400]), function(x) {
  suppressMessages(nhdplusTools::subset_nhdplus(x, 
                               nhdplus_data = "download", 
                               status = FALSE))
}, future.seed = TRUE))
# run individually with 2 workers
system.time(future.apply::future_lapply(comids[1:200], function(x) {
  suppressMessages(nhdplusTools::subset_nhdplus(x, 
                               nhdplus_data = "download", 
                               status = FALSE))
}, future.seed = TRUE))
future::plan(future::multisession, workers = 8)
# run individually with 8 workers
# notice that this is faster but not 4x taster
system.time(future.apply::future_lapply(comids[1:200], function(x) {
  suppressMessages(nhdplusTools::subset_nhdplus(x, 
                               nhdplus_data = "download", 
                               status = FALSE))
}, future.seed = TRUE))

Object Stores and File Servers

Object stores are different than APIs in that they are designed to handle parallelism. If downloading many files from an object store, doing so in parallel can increase total through put assuming you have overall bandwidth to spare. A file server, if not backed by an object store will typically not support parallelism as files are not necessarily stored on a file system that is designed with parallel access in mind. It’s always a good idea to do some testing at small scale if you have long running processes that work over the internet to make sure you are using a pattern that makes sense with the baseline performance characteristics of the server.

Geospatial data representation fundamentals: simple features and geospatial grids

• *Vector data are comprised of points, lines, and polygons that represent discrete spatial entities, such as a river, watershed, or stream gauge.

• Raster data divides spaces into rectilinear cells (pixels) to represent spatially continuous phenomena, such as elevation or the weather. The cell size (or resolution) defines the fidelity of the data.

For Vector data Simple Features (officially Simple Feature Access) is both an OGC and International Organization for Standardization (ISO) standard that specifies how (mostly) two-dimensional geometries can represent and describe objects in the real world. Simple features includes:

• a class hierarchy
• a set of operations
• binary and text encodings

It describes how such objects can be stored in and retrieved from databases, and which geometrical operations should be defined for them.

It outlines how the spatial elements of POINTS (XY locations with a specific coordinate reference system) extend to LINES, POLYGONS and GEOMETRYCOLLECTION(s).

The “simple” adjective also refers to the fact that the line or polygon geometries are represented by sequences of points connected with straight lines that do not self-intersect.

Simple and valid geometries and ring direction

This breakdown of simple features follows for the most part this section in Spatial Data Science For linestrings to be considered simple they must not self-intersect:

Code

library(sf)

Linking to GEOS 3.11.1, GDAL 3.6.2, PROJ 9.1.1; sf_use_s2() is TRUE

Code

(ls <- st_linestring(rbind(c(0,0), c(1,1), c(2,2), c(0,2), c(1,1), c(2,0))))

LINESTRING (0 0, 1 1, 2 2, 0 2, 1 1, 2 0)

is_simple 
    FALSE 

For polygons several other conditions have to be met to be simple:

• polygon rings are closed (the last point equals the first)
• polygon holes (inner rings) are inside their exterior ring
• polygon inner rings maximally touch the exterior ring in single points, not over a line
• a polygon ring does not repeat its own path
• in a multi-polygon, an external ring maximally touches another exterior ring in single points, not over a line

z and m coordinates As well as having the necessary X and Y coordinates, single point (vertex) simple features can have:

• a Z coordinate, denoting altitude, and/or
• an M value, denoting some “measure”

Text and binary encodings A key part of the standard feature encoding is text and binary encodings. The well-known text (WKT) encoding we have shown above gives us a human-readable description of the geometry. The well-known binary (WKB) encoding is machine-readable, lossless, and faster to work with than text encoding. WKB is used for all interactions with GDAL and GEOS.

Operations on geometries We can break down operations on geometries for vector features in the following way:

• predicates: a logical asserting a certain property is TRUE
• measures: a quantity (a numeric value, possibly with measurement unit)
• transformations: newly generated geometries

We can look at these operations by what they operate on, whether the are single geometries, pairs, or sets of geometries:

• unary when it’s a single geometry
• binary when it’s pairs of geometries
• n-ary when it’s sets of geometries

Unary predicates work to describe a property of a geometry.

A list of unary predicates:

predicate	meaning
is	Tests if geometry belongs to a particular class
is_simple	Tests whether geometry is simple
is_valid	Test whether geometry is valid
is_empty	Tests if geometry is empty

A list of binary predicates is:

predicate	meaning	inverse of
contains	None of the points of A are outside B	within
contains_properly	A contains B and B has no points in common with the boundary of A
covers	No points of B lie in the exterior of A	covered_by
covered_by	Inverse of covers
crosses	A and B have some but not all interior points in common
disjoint	A and B have no points in common	intersects
equals	A and B are topologically equal: node order or number of nodes may differ; identical to A contains B and A within B
equals_exact	A and B are geometrically equal, and have identical node order
intersects	A and B are not disjoint	disjoint
is_within_distance	A is closer to B than a given distance
within	None of the points of B are outside A	contains
touches	A and B have at least one boundary point in common, but no interior points
overlaps	A and B have some points in common; the dimension of these is identical to that of A and B
relate	Given a mask pattern, return whether A and B adhere to this pattern

See the Geometries chapter of Spatial Data Science for a full treatment that also covers **unary and binary measures* as well as unary, binary and n-ary transformers

Raster data model

You can read the GDAL raster data model and OpenGIS Grid Coverages specification but with a raster data model (a cell-based tesselation) you can read / write and operate on raster data in numerous formats using gdal:

Drainage basins and catchments - mainstems and flowpaths

When writing software for hydrologic data, concrete conceptual and logical definitions for the spatial features our software works with are critical to enabling interoperability. Along these lines, some key definitions to consider:

• Catchment: A physiographic unit with zero or one inlets and one outlet. A catchment is represented by one or more partial realizations; flowpath, divide, and networks of flowpaths and divides.
• Nexus: Conceptual outlet for water contained by a catchment. The hydro nexus concept represents the place where a catchment interacts with another catchment.
• Flowpath: A flowpath is a linear geometry that represents the connection between a catchment’s inlet and its outlet. All flowpaths have a local drainage area and may be aggregates of flowlines.
• Flowline: A flowline is a linear geometry that represents a segment of a flowing body of water. Some flowlines have no local drainage area and are never aggregate features.
• Drainage Basin: A catchment with zero inlets and one (internal or external) outlet.
• Mainstem: The flowpath of a drainage basin.

In the following, we create a representation of catchment divides and flowpaths with the hydrologic locations that represent their nexuses.

Note: both the divide and flowpath are said to be realizations of the overall catchment that they represent. In other words, the divide and flowpath are both part of the representation of a catchment.

Code

source(system.file("extdata/new_hope_data.R", package = "nhdplusTools"))

catchment <- sf::st_geometry(new_hope_catchment)
flowpath <- sf::st_geometry(dplyr::filter(new_hope_flowline, COMID %in% new_hope_catchment$FEATUREID))
nexus <- sf::st_geometry(nhdplusTools::get_node(flowpath, "end"))


plot_window <- sf::st_as_sfc(sf::st_bbox(dplyr::filter(new_hope_catchment, FEATUREID %in% c(8891178, 8895564))))

par(mar = c(0,0,0,0))
plot(plot_window, col = NA, border = NA)
plot(catchment, col = NA, border = "grey25", add = TRUE)
plot(flowpath, col = "dodgerblue3", add = TRUE)
plot(nexus, col = "springgreen", add = TRUE, pch = 20)

In this example, we create a drainage basin boundary (divide), mainstem flowpath of the drainage basin, and the flowlines that make up the hydrographic network of the drainage basin.

Fun Fact: the word “watershed” has come to refer to the land encompassed by a drainage divide but this usage is not correct. A watershed is “a dividing ridge between drainage areas” which is in line with the non hydrologic use of the word: a crucial dividing point, line, or factor.

Code

basin <- sf::st_geometry(sf::st_union(new_hope_catchment, by_feature = FALSE))
flowline <- sf::st_geometry(new_hope_flowline)
mainstem <- sf::st_geometry(new_hope_flowline[new_hope_flowline$LevelPathI == min(new_hope_flowline$LevelPathI),])

par(mar = c(0,0,0,0))
plot(basin, lwd = 2) 
plot(flowline, col = "dodgerblue", add = TRUE)
plot(mainstem, col = "blue", lwd = 2, add = TRUE)

sf: simple features

In R, the sf package provides “support for simple features, a standardized way to encode spatial vector data…. [and] Binds to ‘GDAL’ for reading and writing data, to ‘GEOS’ for geometrical operations, and to ‘PROJ’ for projection conversions and datum transformations.”

When using R, you’ are’re using an interface to the core community standards, software, and practices (this isn’t exclusive to R). TO highlight this we can install (do this once) and attach sf to view the external dependencies versions of the libraries linked to sf.

Code

# install.packages("sf")
library(sf)

sf_extSoftVersion()

          GEOS           GDAL         proj.4 GDAL_with_GEOS     USE_PROJ_H 
      "3.11.1"        "3.6.2"        "9.1.1"         "true"         "true" 
          PROJ 
       "9.1.1" 

The bindings to these lower-level C libraries, and, the larger sf ecosystem in R can be seen below:

In the sf implementation in the R ecosystem stores simple feature geometries (sfg) as part of a larger data.frame using a simple feature geometry list-column (sfg). The collection of attribute and spatial information define a simple feature that can be operated on in both table (SQL) and spatial (GEOS, etc) contexts. Not only does this allow us to make the most use of the growing spatial community but also of the growing data science community (see ggplot, dplyr, data.table, dbplyr, arrow, etc.)

In practice, an sf object in R looks like the following:

We can break this down following examples presented in the recently published Spatial Data Science by Edzar Pebesma and Rober Bivand. The most common simple feature geometries used to represent a single feature are:

type	description
POINT	single point geometry
MULTIPOINT	set of points
LINESTRING	single linestring (two or more points connected by straight lines)
MULTILINESTRING	set of linestrings
POLYGON	exterior ring with zero or more inner rings, denoting holes
MULTIPOLYGON	set of polygons
GEOMETRYCOLLECTION	set of the geometries above

This extends the idea of “tidy” data in that each row represents one observation, which has one geometric representation of the real world feature it describes.

An example of basic use:

Code

# Define file path
filename <- system.file("shape/nc.shp", package="sf")

# read in file
(nc <- read_sf(filename))

      col = "red", add = TRUE)
 plot(slice_max(nc, AREA, n =5)$geometry,

 plot(slice_max(nc, AREA, n = 1)$geometry, 
      col = "green", add = TRUE)
}

Measure (GEOS Measures)

Measures are the questions we ask about the dimension of a geometry, once a coordinate reference system has been established and we can compute: - How long is a line or polygon perimeter? (unit) - What is the area of a polygon? *(unit^2) - How far are two objects from one another? (unit)

• Measures come from the GEOS library
• Measures are calculated in the units of the projection

We’ll demonstrate with a toy dataset of USGS gages in a data package from a previous workshop:

Code

# remotes::install_github("mhweber/awra2020spatial")
gages <- read.csv(system.file("extdata", "Gages_flowdata.csv", package = "awra2020spatial")) |> 
  dplyr::select(SOURCE_FEA, STATE, LAT_SITE, LON_SITE)

Rows: 2,771
Columns: 4
$ SOURCE_FEA <int> 14361500, 14344500, 10378500, 14341500, 14343000, 13092500,…
$ STATE      <chr> "OR", "OR", "OR", "OR", "OR", "ID", "OR", "OR", "OR", "OR",…
$ LAT_SITE   <dbl> 42.43040, 42.42763, 42.42488, 42.40819, 42.40263, 42.39648,…
$ LON_SITE   <dbl> -123.3178, -122.6011, -119.9233, -122.6011, -122.5373, -114…

Using st_as_sf in sf we can easily make a data frame with coordinates into a simple features data frame

Code

gages <- gages |> 
  sf::st_as_sf(coords = c("LON_SITE", "LAT_SITE"), crs = 4269)

Rows: 2,771
Columns: 3
$ SOURCE_FEA <int> 14361500, 14344500, 10378500, 14341500, 14343000, 13092500,…
$ STATE      <chr> "OR", "OR", "OR", "OR", "OR", "ID", "OR", "OR", "OR", "OR",…
$ geometry   <POINT [°]> POINT (-123.3178 42.4304), POINT (-122.6011 42.42763)…

What is the distance from the first stream gage to the second stream gage?

Code

sf::st_distance(gages[1,], gages[2,])

Units: [m]
         [,1]
[1,] 58822.95

We can generate toy area by buffering a point (to make a polygon) and find area and perimeter. We need to project into a planar CRS to get perimeter so we will project to an Albers projection using an epsg code:

Code

poly <- sf::st_buffer(gages[1,],200)
sf::st_area(poly)

127234.3 [m^2]

Code

poly <- sf::st_transform(poly, 5070)
lwgeom::st_perimeter(poly)

1713.517 [m]

terra for raster data

We’ll look at using terra for working with raster data in R - stars is another library for working with raster data and spatiotemporal arrays (raster and vector data cubes) but for the sake of time we won’t demonstrate stars in this workshop.

terra builds on the older raster package and provides methods for low-level data manipulation as well as high-level global, local, zonal, and focal computations. The predict and interpolate methods facilitate the use of regression type (interpolation, machine learning) models for spatial prediction, including with satellite remote sensing data. Processing of very large files is supported.

Like sf, terra links to GDAL, and the version and drivers can be viewed using package support functions:

Code

# install.packages(terra)
library(terra)

gdal()

[1] "3.6.2"

Code

DT::datatable(gdal(drivers = TRUE))

We can get raster data the National Map family of APIs and in particular 3DEP Elevation data and work with it using terra or stars. We’ll use Mike Johnson’s AOI package to get a county polygon to use as a template to pass to terrainr for our area of interest

Code

library(terrainr)
# remotes::install_github("mikejohnson51/AOI")
library(AOI)

The legacy packages maptools, rgdal, and rgeos, underpinning this package
will retire shortly. Please refer to R-spatial evolution reports on
https://r-spatial.org/r/2023/05/15/evolution4.html for details.
This package is now running under evolution status 0 

Code

library(mapview)
mapviewOptions(fgb=FALSE)

AOI::aoi_get(list("Corvallis, OR", 10, 10)) |> mapview()

Code

# aoi <- AOI::aoi_get(state = "OR", county = "Benton")
aoi <- AOI::aoi_get(list("Corvallis, OR", 10, 10))
output_tiles <- terrainr::get_tiles(aoi,
                          services = c("elevation", "ortho"),
                          resolution = 30 # pixel side length in meters
                          )

Code

terra::plot(terra::rast(output_tiles[["elevation"]][[1]]))

Code

terra::plotRGB(terra::rast(output_tiles[["ortho"]][[1]]),scale = 1)

We can also use the [elevatr] package by Jeff Hollister for accessing elevation data through web services and clip out elevation to a watershed basin we access through nhdplusTools and the NLDI.

Note that get_elev_raster from elevatr will generate a set of warnings, particularly regarding retirement of rgdal - the package will need to be updated to conform with retirement of rgdal, rgeos and maptools.

Code

library(nhdplusTools)
library(elevatr)
library(mapview)
mapviewOptions(fgb=FALSE)
# We're passing an identifier for the stream reach (and catchment) that we know is the downstream-most segment on the Calapooia River using the COMID below
start_comid = 23763529
nldi_feature <- list(featureSource = "comid", featureID = start_comid)
basin <- nhdplusTools::get_nldi_basin(nldi_feature = nldi_feature)

x <- get_elev_raster(basin, z = 12)
# x is returned as a raster object rather than a terra spatraster, so we need to convert to spatraster
mapview::mapview(basin) + mapview(x)

Warning in rasterCheckSize(x, maxpixels = maxpixels): maximum number of pixels for Raster* viewing is 5e+05 ; 
the supplied Raster* has 19843980 
 ... decreasing Raster* resolution to 5e+05 pixels
 to view full resolution set 'maxpixels =  19843980 '

We can also crop the elevation raster to our basin using terra - note that mapview expects raster objects rather than terra SpatRasters so we need to convert between terr and raster.

Code

library(raster)

Loading required package: sp

Attaching package: 'raster'

The following object is masked from 'package:dplyr':

httr and jsonlite

In R, httr and jsonlite packages are used to consume the API’s that provide data in json format.

httr httr provides us with an HTTP client to access the API with GET/POST methods, passing query parameters, and verifying the response with regard to the data format.

jsonlite This R package is used to convert the received json format to readable R object or data frame. jsonlite can also be used to convert R objects or a data frame to a json format data type.

Along with these two packages, rlist in R can be used to perform additional manipulation on the received json response. list.stack and list.select are two important methods exposed by rlist that can be used to get parsed json data into a tibble.

To learn about these (and other) packages, type ?httr, ?jsonlite and ?rlist in the console of Rstudio to view the documentation.

Here we see an example using a JSON API from the world bank that uses a GET request below - we can see a couple ways of passing request parameters - first we’ll embed the query directly in the URL for the request itself:

Code

library(httr) 
library(jsonlite) 
library(dplyr)
library(data.table)

jsonResponse <- httr::GET("http://api.worldbank.org/country?per_page=10&region=OED&lendingtype=LNX&format=json")

We can also generate the query by passing it in a separate list we create and adding as a query parameter in the GET request

Code

query<-list(per_page="10",region="OED",lendingtype="LNX",format="json")
jsonResponse <- httr::GET("http://api.worldbank.org/country",query=query)

The jsonlite package can be used to parse our response which we indicated above to return as json. Why does the attempt below return an error?

Code

df <- jsonlite::fromJSON(jsonResponse)

HINT: what type of object is jsonResponse above?

Code

typeof(jsonResponse)

[1] "list"

We can also get information about the response using httr:

Code

http_type(jsonResponse)

[1] "application/json"

We have a list - let’s take a look to figure out to pull out what we want into a data frame:

Code

names(jsonResponse)

 [1] "url"         "status_code" "headers"     "all_headers" "cookies"    
 [6] "content"     "date"        "times"       "request"     "handle"     

It seems like content is what we want, how do we pull out?

Code

df <- jsonlite::fromJSON(jsonResponse$content)

Still doesn’t work - we need to do some further parsing of this response using content in httr which we can then pass to jsonlite and the fromJSON function to get data into a data frame

Code

jsonResponseParsed <- httr::content(jsonResponse, as="parsed")
is.list(jsonResponseParsed)

[1] TRUE

Code

names(jsonResponseParsed[[1]])

[1] "page"     "pages"    "per_page" "total"   

Code

names(jsonResponseParsed[[2]])

NULL

Code

#Hmmm
is.list(jsonResponseParsed[[2]][[1]]) 

[1] TRUE

Code

names(jsonResponseParsed[[2]][[1]])

 [1] "id"          "iso2Code"    "name"        "region"      "adminregion"
 [6] "incomeLevel" "lendingType" "capitalCity" "longitude"   "latitude"   

Code

# now we're getting somewhere...
names(jsonResponseParsed[[2]][[2]])

 [1] "id"          "iso2Code"    "name"        "region"      "adminregion"
 [6] "incomeLevel" "lendingType" "capitalCity" "longitude"   "latitude"   

We convert the parsed json response list to data table using lapply and rbindlist:

Code

df <- lapply(jsonResponseParsed[[2]],as.data.table) 
typeof(df) # still a list - one more step

[1] "list"

Code

dt <- rbindlist(df, fill = TRUE)

Some APIs like GitHub are easier to pull directly into a dataframe using fromJSON

Code

myGitHubRepos <- fromJSON("https://api.github.com/users/mhweber/repos")

# It returns 79 variables about my repos - we can use select to just get the ones we want to see
myGitHubRepos <- myGitHubRepos |> 
  dplyr::select(name, stargazers_count, watchers_count, language, has_issues, forks_count)
head(myGitHubRepos)

Data access summary

This just builds on examples for Working with Geospatial Hydrologic Data Using Web Services (R) for IOW Webinar

AOI

AOI is NOT on CRAN but provides interfaces for geocoding and retrieving spatial boundaries (e.g state, county, and country). When working with web-based, subsetting services, the ability to quickly define common features is really convenient.

We’ll see through these examples that the concept of AOI is key to requesting subsets of data. Further well see that a reproducible way of generating these is a quic kway to make the sytanx of disparate packages more aligned.

Code

# remotes::install_github("mikejohnson51/AOI")
library(AOI)

# state
aoi_get(state = "OR") |> mapview()

Code

# county
aoi_get(state = "OR", county = "Benton") |> mapview()

Code

# country
aoi_get(country = "Ukraine") |> mapview()

Code

# geocoding
geocode("LaSells Stewart Center Corvallis", pt = TRUE) |> mapview()

nhdplusTools

We’ll hear a lot about Dave’s package nhdplusTools - it’s primarily a R package for working with the NHD and the NHD data model. The package covers 5 primary use topics that include:

1. data access
2. data discovery and subsetting (via web services)
3. Indexing and Network Navigation
4. Network Navigation
5. Network Attributes

Given the focus here on geospatial data via web services, we will look at functions supporting use case 2.

Basic Use

Let’s get data for an AOI around Corvalis. We use AOI::aoi_get to get the OpenStreetMap representation of Corvallis, and initialize an empty list to populate:

Code

corvallis     = list()
corvallis$AOI = aoi_get("Corvallis, OR")

Populate our Corvallis list with various elements we pull from get_ functions in nhdplusTools:

Code

corvallis$nhdplus      <- get_nhdplus(AOI = corvallis$AOI) 

Spherical geometry (s2) switched off

although coordinates are longitude/latitude, st_intersects assumes that they
are planar

Spherical geometry (s2) switched on

Code

corvallis$waterbodies  <- get_waterbodies(AOI = corvallis$AOI)

Code

corvallis$gages        <- get_nwis(AOI = corvallis$AOI) 
corvallis$huc12        <- get_huc12(AOI = corvallis$AOI) 

Warning in get_huc12(AOI = corvallis$AOI): this function is deprecated -- use
get_huc(..., type = "huc12") instead

Spherical geometry (s2) switched off

although coordinates are longitude/latitude, st_intersects assumes that they

Code

# How many features per entry?
sapply(corvallis, nrow)

        AOI     nhdplus waterbodies       gages       huc12 
          1          45           9           2           6 

Code

mapview(corvallis)

In both the NHDPlus data model, and the emerging international OGC standard for representing surface water features HY_features it’s recognized that hydrologic entities can be “realized” in a number of ways.

For example the holistic notion of a ‘catchment’ can be realized as a ‘divide’, ‘flowpath’, ‘outlet’, or other representation. The nhdplusTools::get_nhdplus functions support getting 3 realizations of the NHD features that are consistent with the NHDPlus Data model (outlet, flowline, catchment, and all).

Code

corvallis <- nhdplusTools::get_nhdplus(aoi_get("Corvallis, OR"), realization = "all")
mapview(corvallis)

dataRetrival

The USGS supported dataRetrieval package provides retrieval functions for USGS and EPA hydrologic and water quality data. Recently a Network Linked Data Index (NLDI) client was also added to the package.

All sorts of dataRetrieval resources: Home page Tutorial for National Water Quality Monditoring Conference - Part 1 Tutorial for National Water Quality Monditoring Conference - Part 2

Basic Use: Get streamflow Data

What were the two gages we picked up geolocating Corvallis?

Code

corvallis$gages

NULL

Code

#install.package('dataRetrieval')
library(dataRetrieval)
library(ggplot2)

# Supply gauge ids from Corvallis example
# Parameter codes can be found with (`dataRetrieval::parameterCdFile`)
# "00060" is stream flow

# we need to bring gages back to corvallis after our last operation
corvallis$AOI = AOI::aoi_get("Corvallis, OR")
corvallis$gages  <- get_nwis(AOI = corvallis$AOI)
flows = readNWISdv(siteNumbers = corvallis$gages$site_no, parameterCd = "00060") |> 
  renameNWISColumns()

ggplot(data = flows) + 
  geom_line(aes(x = Date, y = Flow)) + 
  facet_wrap('site_no')

water quality

We can also get water quality information - see the NWQMC DataRetrieval Tutorial Part 1 for all the details

Code

Let’s explore phosphorus data in Benton County

Code

benton_phos <- readWQPsummary(statecode = "OR",
                          countycode="Benton",
                          sampleMedia = "Water",
                          characteristicName = "Phosphorus")

names(benton_phos) 

 [1] "Provider"                           "MonitoringLocationIdentifier"      
 [3] "YearSummarized"                     "CharacteristicType"                
 [5] "CharacteristicName"                 "ActivityCount"                     
 [7] "ResultCount"                        "LastResultSubmittedDate"           
 [9] "OrganizationIdentifier"             "OrganizationFormalName"            
[11] "MonitoringLocationName"             "MonitoringLocationTypeName"        
[13] "ResolvedMonitoringLocationTypeName" "HUCEightDigitCode"                 
[15] "MonitoringLocationUrl"              "CountyName"                        
[17] "StateName"                          "MonitoringLocationLatitude"        
[19] "MonitoringLocationLongitude"       

Apply some dplyr functions to group site information

Code

benton_phos_summary <- benton_phos |> 
  rename(Site = MonitoringLocationIdentifier) |>
  mutate(Lat = as.numeric(MonitoringLocationLatitude),
         Lon = as.numeric(MonitoringLocationLongitude)) |> 
  group_by(Site, Lat, Lon) |> 
  summarise(min_year = min(YearSummarized),
            max_year = max(YearSummarized),
            count = sum(ResultCount)) |> 
  mutate(POR = max_year - min_year) |> 
  arrange(desc(count)) |> 
  ungroup()

`summarise()` has grouped output by 'Site', 'Lat'. You can override using the
`.groups` argument.

Code

View with mapview- first we need to make our results an sf data frame for mapview to use. Easy!

Code

results_sf <- benton_phos_summary  |> 
  sf::st_as_sf(coords = c("Lon", "Lat"), crs = 4269, remove = FALSE)
mapview(results_sf)

NLDI client

The hydro Network-Linked Data Index (NLDI) is a system that can index spatial and river network-linked data and navigate the river network to allow discovery of indexed information.

The NLDI service requires the following:

1. A starting entity (comid, nwis, wqp, location and more).

• The “more” includes the ever-growing set of resources available in the NLDI service that can be accessed with the get_nldi_sources function.

Code

DT::datatable(get_nldi_sources())

2. A direction to navigate along the network

• UM: upper mainstem
• UT: upper tributary
• DM: downstream mainstem
• DD: downstream divergence

3. Features to find along the way!

• Any of the above features (e.g. get_nldi_sources)
• flowlines
• basin

Basic use: NLDI

The NLDI client in dataRetrival operates by speficing the origin, the navigation mode, and the features to find. In the following example, we want to navigate along the upstream tributary of COMID 101 (up to 1000 km) and find all flowline features, nwis gages, and the contributing drainage area.

Code

nldi = findNLDI(comid= 23763529, 
             nav= "UT", 
             find= c("flowline", "nwis", 'basin'),
             distance_km = 1000)

sapply(nldi, nrow)

      origin        basin  UT_nwissite UT_flowlines 
           1            1           15          187 

Code

mapview(nldi)

nwmTools

While dataRetrival provides retrieval functions for observed data, there is an increasing amount of simulated data available for use. Once example is the 3 retrospective simulations of the National Water Model. This data certainly falls under the umbrella of “big data” and can be difficult to work with given each hourly file (for up to 42 years!) is stored in separate, cloud based files.

nwmTools provides retrieval functions for these retrospective stream flow data from the NOAA National Water Model reanalysis products:

Aggregation

The timestep of the retrospective NWM data is hourly. In many cases, its more desirable to have the time step aggregated to a different temporal resolution. nwmTools provides a family of aggregation functions that allow you to specify the aggregation time period, and the aggregation summary statistic

Code

grep('aggregate_', ls("package:nwmTools"), value = TRUE)

opendap.catalog

One of the biggest challenges with Earth System and spatial research is extracting data. These challenges include not only finding the source data but then downloading, managing, and extracting the partitions critical for a given task.

Services exist to make data more readily available over the web but introduce new challenges of identifying subsets, working across a wide array of standards (e.g. non-standards), all without alleviating the challenge of finding resources.

In light of this, opendap.catalog provides 4 primary services.

With 14,160 web resources documented, there are simply too many resources to search through by hand unless you know exactly what you want. This voids the possibility of serendipitous discovery. So, we have added a generally fuzzy search tool to help discover datasets.

Say you want to find what resources there are for daily rainfall? search and search_summary can help:

Code

opendap.catalog::search("daily precipitation") |> 
  opendap.catalog::search_summary() |> 
  DT::datatable()

Code

# (s = opendap.catalog::search('gridmet daily precipitation'))

Pass catalog elements to the generalized toolsets:

Now that you know the precipitation product you want, lets say we want to look at precipitation in Benton County in April 2022:

Code

(s = opendap.catalog::search('gridmet daily precipitation'))

(OR_rain = opendap.catalog::dap(catalog = s, 
             AOI = AOI::aoi_get(state = "OR"), 
             startDate = "2022-04-01",
             endDate   = "2022-09-30"))

{
  plot(sum(OR_rain[[1]]) * 0.001, 
       main = "Meters of rainfall: Oregon April 2022")
}

Tiled data streams

One of the key features of dap is the capacity to make requests over tiled resources. Some resources (like MODIS) are tiled in space, and some (like MACA, and LOCA) are tiled in time. Below we see an example of how a single dap call can consolidate a request that covers multiple spatial tiles:

Code

(s = opendap.catalog::search('mod16a2v006 PET'))
dap = dap(
    catalog = s,
    AOI = AOI::aoi_get(state = "OR", county = "Benton"),
    startDate = "2010-01-01",
    endDate   = "2010-01-31"
  )

Zonal analysis

#| eval: false Often out goal when acquiring spatial dat is producing area-based summaries, particularly for watershed analyses.

zonal is a package that wraps the excellent exactextractr package with some added performance and convenience for these types of tasks.

To use zonal, you must supply:

1. a raster dataset (SpatRaster)
2. a geometry set to summarize over
3. a summary function (similar to nwmTools::aggregate_*)
4. The column with a unique identifier for each polygon object, and whether the summary data should be joined (join = TRUE) to the original summary data.

zonal

Often getting spatial data is not the end goal and in many cases producing area based summaries is critical.

zonal is a package that wraps the excellent exactextractr package with some added performance and convenience for these types of tasks. To use zonal, you must supply a raster dataset (SpatRaster), a geometry set to summarize over, and a summary functions (similar to nwmTools::aggregate_*). Lastly, you must provide the column with a unique identifier for each polygon object, and whether the summary data should be joined (join = TRUE) to the original summary data.

Code

# remotes::install_github("NOAA-OWP/zonal")
library(zonal)

# Summary options
zonal::ee_functions()
zonal::weight_functions()

Basic Use

Code

library(zonal)
OR_counties <- AOI::aoi_get(state = "OR", county = "all")
system.time({
summary_data = execute_zonal(OR_rain, 
                             geom = OR_counties, 
                             fun = "sum", 
                             ID = "fip_code", 
                             join = TRUE)
})

Code

plot(summary_data[grepl("sum", names(summary_data))], border = NA,
     max.plot = 20)

Web data without a “service”

Often the needed data is not delivered by a service or function. This does not mean we are out of luck, but rather that we have to do a little of the “heavy lifting” ourselves. This final section highlights how to vector and raster data from a URL using the http/https and s3 protocols.

These approaches are advantageous when you don’t want to download data locally for analysis.

Access Raster Data

GDAL provides a number of Virtual File System drivers to read compressed and network data.

Three of the most useful for common spatial data tasks include:

• vsizip –> file handler that allows reading ZIP archives on-the-fly without decompressing them beforehand.

• vsicurl –> A generic file system handler exists for online resources that do not require particular signed authentication schemes

• vsis3 –> specialized into sub-filesystems for commercial cloud storage services (e.g. AWS, also see /vsigs/, /vsiaz/, /vsioss/ or /vsiswift/).

Basic Usgage

Duke store VRT files for the POLARIS soils dataset. terra can generate pointers to these datasets - however data is not extracted until an operation is called on the data. As seen above dap provides simplified access to extract subsets of data for OpenDap and VRT endpoints.

Code

terra::rast('/vsicurl/http://hydrology.cee.duke.edu/POLARIS/PROPERTIES/v1.0/vrt/alpha_mean_0_5.vrt') 

class       : SpatRaster 
dimensions  : 97200, 212400, 1  (nrow, ncol, nlyr)
resolution  : 0.0002777778, 0.0002777778  (x, y)
extent      : -125, -66, 23, 50  (xmin, xmax, ymin, ymax)
coord. ref. : lon/lat WGS 84 (EPSG:4326) 
source      : alpha_mean_0_5.vrt 
name        : alpha_mean_0_5 

Code

opendap.catalog::dap('/vsicurl/http://hydrology.cee.duke.edu/POLARIS/PROPERTIES/v1.0/vrt/alpha_mean_0_5.vrt', AOI = AOI::aoi_get(state = "OR", county = "Benton")) |> 
  plot()

Transect example

Here is an example where a global elevation dataset can quickly be used in conjunction with the NLDI client to plot the elevation transect of a the Calapooyia River near here:

Code

d = dataRetrieval::findNLDI(loc = geocode("Pioneer Park Brownsville, Oregon", pt = TRUE),
             nav = "UM", 
             find = c("flowlines", "basin")) 

mapview::mapview(d)

Code

COP30 = opendap.catalog::dap("/vsicurl/https://opentopography.s3.sdsc.edu/raster/COP30/COP30_hh.vrt", 
            AOI = d$basin)

transect = terra::extract(COP30, terra::vect(sf::st_union(d$UM_flowlines))) |> 
  dplyr::mutate(location = c(n():1))

ggplot2::ggplot(transect, aes(x = location, y = COP30_hh)) +
    geom_line() +
    geom_smooth()

`geom_smooth()` using method = 'gam' and formula = 'y ~ s(x, bs = "cs")'

Access Vector Data

Basic Usgage: TIGER lines Since the base data reader of sf is GDAL the vsi capabilities also apply to vector data! Note that the tigris and tidycensus packages are the recommended way to access US Census data, this is simply by way of example. The added challenge typically is that vector data (especially shapefile data) is generally stored in zip files. This adds an extra layer of complexity when remotely reading these datasets.

In this example we look at the US Census Bureaus FTP server for TIGER road lines. The data is stored by by 5 digit (county) FIP code in zip files. To access this data we need to identify the FIP code of interest and then chain a vsizip with a vsicurl call.

Code

AOI  = AOI::aoi_get(state = "OR", county = "Benton")
file = paste0('tl_2021_',AOI$fip_code, '_roads')
url  = paste0('/vsizip/{/vsicurl/https://www2.census.gov/geo/tiger/TIGER2021/ROADS/', file, '.zip}/',file,'.shp')

system.time({
  roads  = sf::read_sf(url)
})
mapview::mapview(roads)

For those curious about the generalization of this, we can see that any GDAL backed software (here terra) can utilize the same URL:

Code

system.time({
  roads2 = terra::vect(url)
})

plot(roads2)

Use Cases

Hydro Addressing

Finding where along a river system some spatial data lies is a key use case for many modeling and analysis tasks. A full discussion is available in the nhdplusTools indexing and referencing vignette.

We need two inputs. Lines to index to and points that we want addresses for. With these inputs, nhdplusTools (and soon hydroloom) supports generation of hydro addresses with get_flowline_index().

The example below is as simple as possible. get_flowline_index() has a number of other capabilities, such as increased address precision and the ability to return multiple nearby addresses, that can be found in the function documentation.

Code

source(system.file("extdata/new_hope_data.R", package = "nhdplusTools"))

fline <- sf::st_transform(sf::st_cast(new_hope_flowline, "LINESTRING"), 4326)

point <- sf::st_sfc(sf::st_point(c(-78.97, 35.916)),
                    crs = 4326)

(address <- nhdplusTools::get_flowline_index(fline, point))

  id   COMID      REACHCODE REACH_meas       offset
1  1 8894158 03030002000064    58.0596 0.0002283261

Code

plot(sf::st_geometry(fline[fline$COMID %in% address$COMID,]))+
  plot(point, add = TRUE)

integer(0)

A natural next step once we’ve found a hydro address is to search upstream or downstream from the location we found. nhdplusTools and soon hydroloom offer a few upstream / downstream search functions. Here we’ll show a couple from nhdplusTools.

Code

up <- nhdplusTools::get_UT(fline, address$COMID)
um <- nhdplusTools::get_UM(fline, address$COMID)
dn <- nhdplusTools::get_DD(fline, address$COMID)
dm <- nhdplusTools::get_DM(fline, address$COMID)

plot(sf::st_geometry(fline), col = "grey", lwd = 0.5)
plot(sf::st_geometry(fline[fline$COMID %in% c(up, dn),]),
     add = TRUE)
plot(sf::st_geometry(fline[fline$COMID %in% c(um, dm),]),
     col = "blue", lwd = 2, add = TRUE)
plot(point, cex = 2, lwd = 2, add = TRUE)

The ability to navigate up or down a mainstem rather than all connected tributaries and diversions, requires some attributes that identify primary up and downstream paths. Without those paths, navigation is still possible but the “main” path navigation method is not. Below, a new function available in hydroloom, navigate_network_dfs() is shown.

Code

# remotes::install_github("DOI-USGS/nhdplusTools@2cb81da")
#| warning: false
net <- hydroloom::add_toids(sf::st_drop_geometry(fline), 
                            return_dendritic = FALSE)

up <- hydroloom::navigate_network_dfs(net, address$COMID, direction = "up")
dn <- hydroloom::navigate_network_dfs(net, address$COMID, direction = "dn")

plot(sf::st_geometry(fline), col = "grey", lwd = 0.5)
plot(sf::st_geometry(fline[fline$COMID %in% c(unlist(up), unlist(dn)),]),
     add = TRUE)
plot(point, cex = 2, lwd = 2, add = TRUE)

BONUS Use Case

Going forward, linear referencing with the predecessor to the NHD will be to a “mainstem” identifier. A “mainstem id” is a Uniform Resource Identifier that works like a Digital Object Identifier. e.g. https://geoconnex.us/ref/mainstems/1435189 is the Calapooia River.

If we know the uri ahead of time, we could look it up like this:

Code

calapooia <- sf::read_sf("https://geoconnex.us/ref/mainstems/1435189")
names(calapooia)

 [1] "id"                           "name_at_outlet"              
 [3] "outlet_drainagearea_sqkm"     "new_mainstemid"

[17] "head_2020huc12"               "downstream_mainstem_id"      
[19] "lengthkm"                     "outlet_2020huc12"            
[21] "encompassing_mainstem_basins" "superseded"                  
[23] "geometry"                    

Code

mapview::mapview(calapooia)

In the future, any data along the Calapooia would just link to that URI and we would know that it is supposed to be linked to that river.

If we don’t know what river our data is on, we can find the URI from a lookup table. The mainstem system is brand new. Over time, mainstem lookup tables will become more ubiquitous. Stay tuned!!

Code

point <- sf::st_sfc(sf::st_point(c(-123.149, 44.565)),
                    crs = 4326)
comid <- nhdplusTools::discover_nhdplus_id(point)
mainstem_lookup <- readr::read_csv("https://github.com/internetofwater/ref_rivers/releases/download/v2.1/nhdpv2_lookup.csv")

Rows: 746277 Columns: 2

Catchment Characteristics and Accumulation

nhdplusTools (only in the latest hydroloom branch) and StreamCatTools can be used to retrieve a wide range of catchment characteristics. See the StremCatTools Vignette for further details and examples.

Code

library(nhdplusTools)
# remotes::install_github("USEPA/StreamCatTools")
library(StreamCatTools)
nhdplusTools::nhdplusTools_data_dir(tempdir())
cat <- sf::st_transform(new_hope_catchment, 4326)

streamcat_chars <- StreamCatTools::sc_get_params(param='name')

nawqa_chars <- nhdplusTools::get_characteristics_metadata()

StreamCatTools::sc_fullname("pctimp2016")

[1] "Mean Imperviousness 2016"

Code

nawqa_chars$description[nawqa_chars$ID == "CAT_TWI"]

[1] "Topographic wetness index, ln(a/S); where ln is the natural log, a is the upslope area per unit contour length and S is the slope at that point.  See http://ks.water.usgs.gov/Kansas/pubs/reports/wrir.99-4242.html and Wolock and McCabe, 1995 for more detail"

Code

twi <- nhdplusTools::get_catchment_characteristics("CAT_TWI", cat$FEATUREID)

twi <- dplyr::rename(twi, CAT_TWI = "characteristic_value")

imp <- StreamCatTools::sc_get_data("pctimp2016", 'catchment', cat$FEATUREID)

cat <- dplyr::left_join(cat, imp, by = c("FEATUREID" = "COMID")) 
  # dplyr::left_join(twi, by = c("FEATUREID" = "comid"))

# plot(cat['CAT_TWI'])
plot(cat['PCTIMP2016CAT'])

With the two catalogs of characteristics above, we have access to nearly any characteristic imaginable and both even offer downstream accumulations of the variables. However, sometimes it is necessary to sample and accumulate data not already available. nhdplusTools supports accumulating drainage area and length and hydroloom, going forward, supports downstream accumulation more generically. Here, we’ll just use one of the examples pulled above to illustrate how this works.

Code

library(dplyr)
accum_df <- sf::st_drop_geometry(fline) |>
  dplyr::select(COMID, FromNode, ToNode, Divergence, AreaSqKM) |>
  hydroloom::add_toids() |>
  dplyr::left_join(dplyr::select(cat, -AreaSqKM), by = c("COMID" = "FEATUREID")) |>
  sf::st_sf() |>
  dplyr::mutate(area_weighted_PCTIMP2016CAT = 
           ifelse(is.na(PCTIMP2016CAT) & AreaSqKM == 0, 
                  yes = 0, no = AreaSqKM * PCTIMP2016CAT))

accum_df <- accum_df |>
  dplyr::mutate(tot_PCTIMP2016CAT = 
           hydroloom::accumulate_downstream(accum_df, "area_weighted_PCTIMP2016CAT") / 
           hydroloom::accumulate_downstream(accum_df, "AreaSqKM"))

plot(cat['PCTIMP2016CAT'])

Code

plot(accum_df['tot_PCTIMP2016CAT'])

Object conversion - When Python objects are returned to R they are converted to R objects by default - but you can deal in native Python types by choosing convert=FALSE in the import function

Code

# import numpy and specify no automatic Python to R conversion
np <- import("numpy", convert = FALSE)

# do some array manipulations with NumPy
a <- np$array(c(1:4))
print (a)

array([1, 2, 3, 4])

Code

sum <- a$cumsum()

# convert to R explicitly at the end
print (py_to_r(a))

[1] 1 2 3 4

Code

py_to_r(sum)

[1]  1  3  6 10

Passing Dataframes between Python and R:

Code

pd <- import("pandas")
penguins <- pd$read_csv("https://vincentarelbundock.github.io/Rdatasets/csv/modeldata/penguins.csv")
dplyr::glimpse(penguins)

Rows: 344
Columns: 8
$ `Unnamed: 0`      <dbl> 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 1…
$ species           <chr> "Adelie", "Adelie", "Adelie", "Adelie", "Adelie", "A…
$ island            <chr> "Torgersen", "Torgersen", "Torgersen", "Torgersen", …
$ bill_length_mm    <dbl> 39.1, 39.5, 40.3, NaN, 36.7, 39.3, 38.9, 39.2, 34.1,…
$ bill_depth_mm     <dbl> 18.7, 17.4, 18.0, NaN, 19.3, 20.6, 17.8, 19.6, 18.1,…
$ flipper_length_mm <dbl> 181, 186, 195, NaN, 193, 190, 181, 195, 193, 190, 18…
$ body_mass_g       <dbl> 3750, 3800, 3250, NaN, 3450, 3650, 3625, 4675, 3475,…
$ sex               <list> "male", "female", "female", NaN, "female", "male", …

Or like this:

Code

import pandas as pd
penguins =pd.read_csv("https://vincentarelbundock.github.io/Rdatasets/csv/modeldata/penguins.csv")
print(penguins.head())

   Unnamed: 0 species     island  ...  flipper_length_mm  body_mass_g     sex
