Geographic Information Systems (GIS)

Baltimore County operates an enterprise geographic information system (GIS) that is available to all County agencies and departments. The County’s GIS is managed by the Office of Information Technology’s Business Applications unit.

The GIS team is responsible for Baltimore County's implementation of the geographic information system and maintains the spatial and associated tabular databases, manages the GIS software, and develops custom applications for the County agencies. It also provides customer service and support to citizens, businesses, government organizations, and County agencies by creating and distributing geographic data products.
