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.

Usage

SoilWeb_spatial_query(
  bbox = NULL,
  coords = NULL,
  what = "mapunit",
  source = "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

Value

The data returned from this function will depend on the query style. See examples below.

Note

SDA now supports spatial queries, consider using SDA_spatialQuery() instead.
