20220606 21472400 1.0 TRUE TRUE Ortho2017 2017 Orthophoto - 3 inch resolution: This document describes the processes used to create the orthoimagery data produced for the District of Columbia from 2017 digital aerial photography. It was flown in early March, completed on March 8, 2017. DUE TO TECHNICAL DIFFICULTIES, THE DOWNTOWN AREA IS NOT COMPRISED OF TRUE ORTHOIMAGERY. THE CONTRACTOR MINIMIZED BUILDING LEAN USING THE INCREASED SIDELAP OF IMAGERY. The aerial imagery acquisition was flown to support the creation of 4-band digital orthophotography with a 3 inch/0.08 meter pixel resolution over the full project area covering the District of Columbia which is approximately 69 square miles. The contractor received waivers to fly in the Flight Restricted Zone (FRZ) and P-56 areas. The ortho imagery was submitted to DC OCTO in GeoTiff/TFW format tiles following the tile scheme provided by OCTO. MrSID and JPEG2000 compressed mosaics were delivered as well using a 50:1 compression ratio. All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters.
