Geographic Information Systems (GIS)

Baltimore County operates an enterprise geographic information system (GIS) that is available to all County agencies and departments. GIS is a tool that displays and analyzes map themes to obtain more information about a feature. The County's GIS is managed in the Office of Information Technology's Business Application Unit.

The County provides access to maps and data online and in-person. The information available online comes in two different formats: static maps and interactive maps. 

Static Maps

Static maps are published map products that are available for viewing, downloading and, if applicable, printing. Generally, these maps are found in reports, publications or presented at public meetings. Not all maps published by the county are available for downloading. Some of the maps are intended for viewing only. 

Interactive Maps

Interactive maps are available using internet map service (IMS) technology. IMS technology allows web users to access the same map data used by County agencies and departments. The capabilities of IMS are limited, so not all data is available through the web.
