Title
Aerial Photography (Orthophoto) - 2017 [District of Columbia--Washington]
Description
2017 Orthophoto - 3 inch resolution imagery service. 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 worked to minimize building lean by using the increased side-lap 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 the District's Chief Technology Office (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 District geospatial data is stored and exported in Maryland State Plane coordinates NAD 83 meters. This dataset provided as an ArcGIS Image service . Please note, the download feature for this image service in Open Data DC provides a compressed PNG, JPEG or TIFF. The compressed MrSID or JPEG2000 mosaic raster datasets are available under additional options when viewing downloads. Requests for the individual GeoTIFF set of images should be sent to open.data@dc.gov .
