SSURGO_spatial_query: Get SSURGO Data via Spatial Query

In soilDB: Soil Database Interface

Description

Get SSURGO Data via Spatial Query to 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

Details

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.

Value

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

Note

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.
