A Geographical Information System (GIS) is an analytical tool that allows an operator to view map layers on a computer screen while accessing databases of the map features. By viewing the map layers simultaneously, one can analyze relationships within and between the different layers. GIS is used on a daily basis for operations in many departments throughout the county. WHY IS GIS IMPORTANT? Geographic information systems (GIS) are widely recognized as essential public policy and management tools that enable more informed decision making, greater efficiency, increased accountability, and better management. Geospatial data plays a critical role in public administration of emergency management, monitoring public health and public safety, crime control, tax assessment, traffic, facilities and municipal infrastructure management, environmental assessment, and economic development. Accordingly, County officials have a significant interest in improving access to accurate, current, and immediately accessible geospatial data to improve their decision making. This enables commercial, academic, private organizations, and all levels of government to: Empower and serve the public Protect our homeland Foster Economic growth Advance Science Manage our Resources Prepare for and respond to emergencies Govern our county HOW IS GIS USED?
