GIS Mission Statement
Enable the City to improve communication and decision-making to ultimately better serve the public through the efficient use of Geographic Information.
What is GIS?
GIS is a technology that links geographic information (features) with descriptive information (attributes). GIS can be described as having multiple layers of data assembled into a digital map. GIS is used to visualize, explore, query, edit, and analyze geographic information.
One of the most valuable aspects of GIS is how data can be analyzed spatially. Spatial querying is the process of selecting features based on location or spatial relationship. The animated image below illustrates how a user can quickly identify all addresses within 500 feet of a Metro stop.

Our Role in Alexandria City Government
GIS is a Division of the Department of Planning and Zoning. The GIS Division is responsible for identifying geographic mapping and analysis needs for the City. Coordination with many city departments such as Real Estate, Police, Fire, and Transportation & Environmental Services, ensures geographic data is maintained in a consistent way from a single source. Some examples of this successful coordination include the conversion of hard copy tax maps into digital parcels, analyzing population shifts for the redistricting of the Alexandria Public School Board, and development of a snow mapping application that provides the ability to track the City’s snow removal activities.
