This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the Rhode Island Soil Survey Program in partnership with the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped.
This dataset depicts information about the kinds and distribution of soils on the landscape.
The attribute data contained in the RIGIS soils data (points, lines, and polygons - version 16) shapefile has been revised from the 2016 RIGIS soils data. This 2016 dataset contains changes to the spatial data (points, lines, polygons) for numerous areas throughout RI, particularly the following USGS Topo-quadrangles: East Killingly, Clayville, North Scituate, Oneco, Coventry and Crompton. The coastal pond of Great Salt Pond are also included. This data is NOT the official USDA-NRCS SSURGO Soils Data for Rhode Island (although the spatial data contained is identical). The attribute information on the RIGIS soil data is NOT the same as the “official” soils data; if you need official soils data please use the Web Soil Survey (http://websoilsurvey.nrcs.usda.gov/app/).
