Get SSURGO Data via Spatial Query
Get SSURGO Data via Spatial Query to SoilWeb
SoilWeb_spatial_query( bbox = NULL, coords = NULL, what = "mapunit", source = "soilweb" )
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 |
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.
The data returned from this function will depend on the query style. See examples below.
This function should be considered experimental; arguments, results,
and side-effects could change at any time. SDA now supports spatial queries,
consider using SDA_query_features instead.
