Soils are a key component of the earth system. A wide range of natural science and ecosystem management disciplines require soil information resources.

Soil Information for Environmental Modeling and Ecosystem Management

The mission of soil-related research at the Center for Environmental Informatics in the College of Earth and Mineral Sciences at The Pennsylvania State University is to serve the community of scientists and managers who require soil information in usable forms and formats.
This web site strives to provide soil information in understandable forms which can be used by non-soil scientists.

www.cei.psu.edu/soiltool

The objective of this project is to provide publicly accessible National maps of individual soil series extent based on the land area of series mapped in the SSURGO 2.1 data source as provided by the Soil Data Mart and classified according to the content of the Soil Classification File and Official Soil Series Descriptions. The basic unit shown on the map will be a soil survey area or county.
