Use esri2sf to get data from an ArcGIS FeatureServer or MapServer for a location

Source: R/get_esri_data.R
get_esri_data.Rd

Wraps the esri2sf::esri2sf() and esri2sf::esri2df() functions to download an ArcGIS FeatureServer or MapServer. Supports spatial filtering with bounding box based on location and filtering by location name (if location name column is provided). As of fall 2022, this package suggests the elipousson/esri2sf fork using httr2.

Usage

get_esri_data(
  url,
  location = NULL,
  dist = getOption("getdata.dist"),
  diag_ratio = getOption("getdata.diag_ratio"),
  unit = getOption("getdata.unit"),
  asp = getOption("getdata.asp"),
  crs = getOption("getdata.crs", 3857),
  where = NULL,
  name = NULL,
  name_col = NULL,
  coords = NULL,
  from_crs = getOption("getdata.crs", 4326),
  clean_names = TRUE,
  token = NULL,
  progress = TRUE,
  quiet = FALSE,
  .name_repair = janitor::make_clean_names,
  ...
)

get_esri_layers(
  location = NULL,
  layers = NULL,
  url = NULL,
  nm = NULL,
  token = NULL,
  clean_names = TRUE,
  quiet = FALSE,
  .name_repair = janitor::make_clean_names,
  ...,
  call = caller_env()
)

get_esri_metadata(
  url,
  token = NULL,
  meta = NULL,
  clean_names = TRUE,
  .name_repair = janitor::make_clean_names,
  call = caller_env()
)

Arguments

url

FeatureServer or MapServer url to retrieve data from. Passed to url parameter of esri2sf::esri2sf() or esri2sf::esri2df() functions. For get_esri_layers(), the optional url must be a service url which is the base url for one or more layer urls.

location

sf, sfc, or bbox object (or other object convertible with as_bbox(). Optional.

dist

buffer distance in units. Optional.

diag_ratio

ratio of diagonal distance of area's bounding box used as buffer distance. e.g. if the diagonal distance is 3000 meters and the "diag_ratio = 0.1" a 300 meter will be used. Ignored when dist is provided.

unit

Units for buffer. Supported options include "meter", "foot", "kilometer", and "mile", "nautical mile" Common abbreviations (e.g. "km" instead of "kilometer") are also supported. Distance in units is converted to units matching GDAL units for x; defaults to "meter"

asp

Aspect ratio of width to height as a numeric value (e.g. 0.33) or character (e.g. "1:3"). If numeric, get_asp() returns the same value without modification.

crs

Cordinate reference system to return, Default: 4326 for sf_to_df() and NULL for df_to_sf().

where

where query string passed to esri2sf, Default: NULL

name, name_col

Name value and name column found in the ArcGIS FeatureServer or MapServer data.

coords

Coordinate columns for input data.frame or output sf object (if geometry is 'centroid' or 'point') Default: c("lon", "lat").

from_crs

For df_to_sf(), coordinate reference system used by coordinates or well known text in data frame.

clean_names

If TRUE, set .name_repair to janitor::make_clean_names() Ignored when get_esri_metadata() is not returning a data.frame, e.g. meta = "id".

token

string for authentication token. defaults to NULL.

progress

Show progress bar from cli::cli_progress_along() if TRUE. Default FALSE.

quiet

If TRUE, use suppressMessages() to prevent the printing of messages about the requested layer. Defaults to FALSE.

.name_repair

Defaults to "check_unique"

...

Arguments passed on to esri2sf::esri2sf

outFields

vector of fields you want to include. default is NULL for all fields.

replaceDomainInfo

If TRUE, add domain information to the return data frame. Default FALSE.

layers

Either a vector with URLs, a named list of urls, or a numeric vector; defaults to NULL. Optional if url is a

nm

Name or vector of names to add to the layers; defaults to NULL.

call

The execution environment of a currently running function, e.g. caller_env(). The function will be mentioned in error messages as the source of the error. See the call argument of abort() for more information.

meta

Name of metadata list value to return from esri2sf::esrimeta, e.g. "name" to return layer name. Defaults to NULL.
