Retrieve ArcGIS REST API spatial layer by spatial query
get_layers_by_spatial.Rd
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 exceptget_spatial_layer
- sp_ref
The spatial reference value
