Download Geospatial Data

Description

Function for directly downloading any arbitrary Geospatial layer data from the NPN Geospatial web services.

Usage

npn_download_geospatial(
  coverage_id,
  date,
  format = "geotiff",
  output_path = NULL
)

Arguments

coverage_id	The coverage id (machine name) of the layer for which to retrieve. Applicable values can be found via the npn_get_layer_details() function under the name column.
date	Specify the date param for the layer retrieved. This can be a calendar date formatted YYYY-mm-dd or it could be a string integer representing day of year. It can also be NULL in some cases. Which to use depends entirely on the layer being requested. More information available from the npn_get_layer_details() function.
format	The output format of the raster layer retrieved. Defaults to "GeoTIFF".
output_path	Optional value. When set, the raster will be piped to the file path specified. When left unset, this function will return a terra::SpatRaster object.

Details

Information about the layers can also be viewed at the getCapbilities page directly: https://geoserver.usanpn.org/geoserver/wms?request=GetCapabilities

Value

returns nothing when output_path is set, otherwise a terra::SpatRaster object meeting the coverage_id, date and format parameters specified.
