get_layers_by_spatial: Retrieve ArcGIS REST API spatial layer by spatial query

In pfrater/arcpullr: Pull Data from an 'ArcGIS REST' API

Retrieve ArcGIS REST API spatial layer by spatial query

Description

These functions are wrappers around get_spatial_layer that are specialized for querying by a spatial layer. They will make a POST request to the query URL which returns data (if available) based on the appropriate spatial feature (geometry) and relationship (sp_rel).

Usage

get_layer_by_poly(url, geometry, sp_rel = "contains", ...)

get_layer_by_line(url, geometry, sp_rel = "intersects", ...)

get_layer_by_point(url, geometry, sp_rel = "intersects", ...)

get_layer_by_multipoint(url, geometry, sp_rel = "intersects", ...)

get_layer_by_envelope(url, geometry, sp_rel = "intersects", ...)

get_layer_by_spatial(
  url,
  geometry,
  geom_type,
  sp_ref = NULL,
  sp_rel = "intersects",
  ...
)

Arguments

url	A character string of the url for the layer to pull
geometry	An sf object used for the spatial query
sp_rel	Character. The type of relationship to query by. Possible options include "intersects", "contains", and "crosses"
...	Additional arguements to pass to get_spatial_layer
geom_type	A character of the geometry type to be used. This param is automatically specified in all get_layer_by_* functions except get_spatial_layer
sp_ref	The spatial reference value

Value

An object of class "sf" of the appropriate layer

Examples

## Not run: 
  mke_waters <- get_layer_by_poly(wi_hydro_url, mke_county)
