Geographic Information Systems


A geographic information system (GIS) is a system for integrating, storing, editing, analyzing, sharing and displaying geographically-referenced information. Geographic information system technology is used at the District for scientific investigations, resource management, asset management, environmental impact assessment, development planning, general cartography and floodplain mapping. The District's GIS Division is composed of two branches. The GIS Solutions Branch deals with database and application development, and the GIS Services Branch provides mapping services. Both branches serve as important internal and external resources.
