The Prince George’s County Planning Department maintains an enterprise Geographic Information System (GIS). Beginning on July 1, 2015 the Planning Department implemented its GIS open data initiative which allows for the distribution of digital data to anyone in the public and private sectors.
The data, which is available at no cost, includes planimetric, property, zoning, terrain, administrative, Census, environmental, historic, infrastructure, and park facility datasets. Over 200 different datasets are available for use and distribution. Detailed information on each dataset can be found at the GIS Data Catalog.
The Planning Department provides the public access to the data but reserves the right to modify or delete the data at any time.
The Planning Department updated the Horizontal Datum data used to store data in August 2021 and is working to update data provided here. Prior to August 2021, data is projected using NAD 83/91 U.S. Feet for the horizontal datum and NAVD 88 U.S. Feet for the vertical datum. After August 2021, the horizontal datum has been updated to NAD83/2011 U.S. Feet. The vertical datum, when present, remains NAVD 88 U.S. Feet.
