The NRWA utilizes a Geographic Information System (GIS) to support the environmental research and analysis conducted within the Nashua River Watershed.

What is a GIS? A GIS is a computer program that links a database of information to spatially distributed features represented on a map. GIS combines the database's ability to store, retrieve, and analyze information with the ability to produce and manipulate maps. GIS use has increased greatly in the last ten years, and GIS is now widely used by planning agencies, conservation organizations, and other natural resource managers.

Some typical GIS uses that are helpful to the work at NRWA are locating sampling sites in relation to potential pollution sources, presenting water quality data for specific sites in a visually interesting way, and inventorying, mapping, and presenting natural resource information. The NRWA is a vendor that assists with the environmental planning and water budget entailed in the Open Space and Resource Protection component of the Community Development Plan under Executive Order 418.

In addition, GIS has tremendous potential as an educational and public information tool. Access to GIS-generated products could be provided to schools, Stream Teams, and individual citizens within the watershed to generate understanding and support for NRWA programs.
