Geographic Information Systems (GIS) are computer maps that link spatial and descriptive data to create intelligent maps allowing users to display, query, manipulate and analyze information spatially. GIS applications for governments include planning and zoning, property assessments, public safety, facility siting and hydrological analysis.

ILGARD has developed models for helping communities, such as the City of Crooksville, St. Clairsville and Nelsonville, use GIS to improve environmental compliance, planning and problem-solving skills. ILGARD is creating a digital database for both of these cities. The database will contain lot-line data digitized from existing plat maps, waterlines and valves, fire hydrants, sewer lines and manholes, and house outlines. The digital database will be used to better inventory the city's infrastructure and eventually allow city managers to make more informed decisions. ILGARD is providing training to St. Clairsville and Nelsonville city officials on the use and implementation of GIS.

ILGARD is providing the equipment, expertise, and staff necessary to create the Monday Creek Geographic Information System (GIS) for the Monday Creek Restoration Project, a partnership of local, state and federal agencies and organizations. The GIS provides an advanced data analysis tool to study the impact and restoration requirements of the extensive abandoned underground and surface coal mining systems in the watershed.

Maps are used for grant writing, to provide public information, and for general restoration efforts, including identifying sites with the worst pollution. Using GIS technology, the collaborative efforts of various government agencies, academia, and local residents are moving the Monday Creek Watershed toward re-establishing a healthy ecosystem.

ILGARD also offers computer mapping workshops. For additional information, see Training.
