The Massachusetts USDA-NRCS, working in cooperation with Mass/GIS and the Massachusetts Department of Food and Agriculture are in the process of digitizing published soil surveys in Massachusetts. The digital maps allow soil survey information to be used with a geographic information system (GIS) along with other resource inventory maps and databases.
A geographic information system (GIS) is a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information (i.e. spatial data). This system should include hardware, software, data and staff. Geographic information systems belong to a family of mapping and drafting programs that includes computer-aided design (CAD) and automated mapping and facilities management (AM/FM). GIS is distinguished from CAD and AM/FM by its capacity to perform complicated analytical functions that often include combining information from different sources to derive meaningful relationships.
Mass/GIS Soil Data: MassGIS Soil Data download site
Digital soil survey information for Massachusetts is available for download from Mass/GIS (click here to go to the Mass/GIS soil data layer description). The Counties of Barnstable, Bristol, Berkshire, Dukes, Essex, Hampden, Hampshire, Nantucket, Norfolk, and Suffolk are currently (December 2003) digitized. The soil coverages are in Massachusetts State Plane, NAD 83 projection. Other counties should be available soon. The goal is to have complete digital soil surveys for Massachusetts.

Digital soil surveys authorized for release by the USDA-NRCS must undergo a certification process to ensure quality control and accuracy, this certification is called the Soil Survey Geographic Data Base (SSURGO). Mapping scales generally range from 1:12,000 to 1:63,360; SSURGO is the most detailed level of soil mapping done by the Natural Resources Conservation Service (NRCS). SSURGO digitizing duplicates the original soil survey maps. This level of mapping is designed for use by landowners, townships, and county natural resource planning and management. The user should be knowledgeable of soils data and their characteristics. For information on downloading the soil maps from the USDA-NRCS visit the Soil Data Mart.
