A collaborative effort between the University of New Hampshire and the Office of Planning and Development at the NH Department of Business and Economic Affairs, the core GRANIT System is housed at the UNH Institute for the Study of Earth, Oceans, and Space in Durham. It includes a geographic database; hardware and software to build, manage, and access the database; and a staff of experts knowledgeable in geographic information systems, image processing, and computer analysis. In addition to database development and maintenance, the GRANIT staff offers a range of application development, training, and related technical services to GIS users in the state and the region. The GRANIT approach to a statewide GIS depends upon the cooperative efforts of a host of agencies, collaborating on various elements of database design and construction as well as application development. The collaboration occurs formally through the NH GIS Steering Committee, the NH GIS Advisory Committee, and the NH Technical Users Group, as well as informally through daily interactions within the community of GIS users in the state and the region.
