Get SSURGO Data via Spatial Query to SoilWeb
Data are currently available from SoilWeb. These data are a snapshot of the "official" data. The snapshot date is encoded in the "soilweb_last_update" column in the function return value. Planned updates to this function will include a switch to determine the data source: "official" data via USDA-NRCS servers, or a "snapshot" via SoilWeb.
Arguments
- bbox
a bounding box in WGS84 geographic coordinates, see examples
- coords
a coordinate pair in WGS84 geographic coordinates, see examples
- what
data to query, currently ignored
- source
the data source, currently ignored
Note
SDA now supports spatial queries, consider using SDA_spatialQuery() instead.
Examples
# \donttest{
# query by bbox
