Geographic Information System (GIS) Base Map Updates

The Maryland-National Capital Park and Planning Commission (M-NCPPC) is soliciting qualified contractors for RFP 46-127, GIS Base Map Updates, to provide professional services to update M-NCPPC's planimetric and topographic base map data for use in its various GIS systems., to be received no later than May 8, 2026, 2:00 PM EST.

The last update project(s) that took place was based on 2023 aerial photography and 2024 LiDAR. Previous projects for Montgomery and Prince George’s County were separately managed but completed by the same contractor. Both Montgomery and Prince George’s County have undergone continued changes, and a new update program is being initiated.

New 2027 aerial photography is being planned for acquisition by the State of Maryland to support orthophoto production. This imagery and the subsequent aerial triangulation and orthoimagery products will be used to support planimetric mapping. In the event the State decides not to proceed with the new imagery the Commission will contract for this service under this contract. The acquisition and orthophoto production work shall be itemized as an optional task in the cost proposal.

This contract will be for an initial update cycle. The Commission reserves the right to extend the contract so the same vendor(s) may perform a second update cycle projected for 2029 for the deliverables herein. Purchase orders will be issued separately by each County and for each phase (e.g. planimetric updates, lidar capture, topographic updates, etc.). Invoices for payment will also be submitted separately.
