GIS DATA

Montgomery County Board of Commissioners authorizes the Mapping & Data Services Division to provide free and open geospatial data to government agencies and entities, members of the public and commercial businesses.  Montgomery County has furnished an Open Data Portal to view and download authoritative GIS data.  The Open Data Portal also provides numerous interactive mapping applications that focus on a wide variety of Montgomery County initiatives and services.

The Map Viewers and Applications, developed using the ESRI ArcGIS technology, allow users to display, find, and identify map features within the county. More applications and data will be published when made available. Contact the Data & Mapping Services division with any questions or issues.

The geographic data layers and applications produced by the Government of Montgomery County, Pennsylvania, and any associated maps and applications, are provided as a public resource. While every reasonable effort is made to ensure the accuracy and completeness of the data, Montgomery County makes no representations about the suitability of this data for any purpose. All data is provided "as is" without warranties of any kind, either express or implied, and it should not be construed or used as a legal description.  https://www.montcopa.org/721/Disclaimer
