Soil and Topography Information

About STI

Soil and Topography Information’s SIS (Soil Information System) is a revolutionary soil mapping technology in which soil information is collected and processed digitally to produce accurate, consistent results, very quickly. Digital soil information from the SIS can be flexibly output as printed or web maps, GIS files in multiple common formats, direct inputs to variable rate controllers, or be distilled into a custom format that addresses a client's specific needs.

SIS has been developed by Soil and Topography Information, Inc, a team of soil scientists, geomorphologists, geo-statisticians, cartographers, and computer scientists working together to create the world's best soil and topographic maps.
