SoilWeb_spatial_query: Get SSURGO Data via Spatial Query

In soilDB: Soil Database Interface

Get SSURGO Data via Spatial Query

Description

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.
