findSSURGO: Find SSURGO Maps and Mapunit Aggregated Attributes

In mikejohnson51/HydroData: HydroData

Description

SSURGO is a geospatial database of soils produced by the Natural Resources Conservation Service (NRCS). findSSURGO returns a SpatialPolygonsDataFrame of SSURGO map units and the Mapunit aggregated attributes (muaggatt table) associated with each MUKEY. In total 43 attributes are returned, all of which can be found in the [SSURGO documentation](https://sdmdataaccess.sc.egov.usda.gov/documents/TableColumnDescriptionsReport.pdf). The MUAGGATT values cover a wide range of soil realted questions however if a user is interested in the full range of tabular data associated with the SSURGO map units we suggest checking out the FedData package.
