GIS

Geographic Information System (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data.  In the simplest terms, GIS is the merging of cartography, statistical analysis, and database technology.

Soil Survey Data Downloads:   

USDA-NRCS is now offering a new detailed soil survey gridded map product with “ready to map” attributes in statewide tiles for desktop GIS called “gSSURGO”. The Gridded Soil Survey Geographic (gSSURGO) Database is now available on the Geospatial Data Gateway (http://datagateway.nrcs.usda.gov/). - NEW!

The gSSURGO dataset was created for use in national, regional, and statewide resource planning and analysis of soils data. The new soil 10m raster map layer data offers rapid display of soil themes over large land areas and is easy to combine with other raster data sources (land cover, terrain data, climate, etc.) in a common equal area projection. Ready to map attributes include soil organic carbon, available water storage, and productivity indices.
