Geographic Information Systems (GIS)

A GIS is a combination of software and data designed to view and manage information about geographic places, analyze spatial relationships and model spatial processes. It provides a framework for gathering and organizing spatial data and related information so it can be displayed and analyzed. The RCD utilizes the most recent technological data available from the USDA-NRCS and views spatial data and GIS as one of many tools to accomplish our program missions and technical needs.


Start building your maps through the Web-Soil Survey now:

Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world. NRCS has soil maps and data available online for more than 95 percent of the nation’s counties and anticipates having 100 percent in the near future. The site is updated and maintained online as the single authoritative source of soil survey information.


Soil surveys can be used for general farm, local, and wider area planning. Onsite investigation is needed in some cases, such as soil quality assessments and certain conservation and engineering applications. For more detailed information, contact your local RCD office.
