Municipal Government Support: GDMIS Employs highly experienced professionals who are familiar with the issues local government agencies face in the area of GIS data collection and management, planning and regulations. GDMIS translates agency priorities to appropriate technical solutions.

GIS Data Support and Photorevision: GDMIS produces digital cartographic products including DLG, thematic maps, and graphics. We update a variety of USGS Digital Line Graph (DLG) feature categories. Data sources include orthophotos, planimetric maps, satellite imagery, existing vector maps, databases, and analog map products.

Watershed-based Water Quality Modeling: GDMIS uses appropriate water quality and runoff simulation models (such as EPA’s BASINS, QUAL2E, TOXIROUTE, HSPF, GWLF and others) to evaluate point and non-point source impacts on water quality and aquatic habitats.

Environmental Health Risks: GDMIS can implement a county-wide GIS to identify environmental risks and provide agency staff with the tools and information to prioritize inspection and permitting resources.

Storm Water Planning: GDMIS processes and integrates high resolution, low-cost satellite imagery with local street and sewer networks to identify “hot-spot” areas that contribute most to storm water problems. This data can be used to estimate the extent of storm water impacts and to target scarce resources for satisfying increasingly stringent federal regulations.
