- Title
- Aerial Photography (Orthophoto) - [District of Columbia--Washington] {2015}
- Description
- 2015 Orthophoto - 3 inch resolution imagery service. Data produced for the District of Columbia from 2015 digital aerial photography. It was flown in mid-April and, completed on April 24th, 2015. Further details included in download XML file. DUE TO THE LOW ALTITUDE FLOWN TO CAPTURE THE COMPLETE IMAGERY FOR THE 2015 SENSOR FLIGHT, THERE IS INCOMPLETE AERIAL PHOTOGRAPHY COVERAGE AROUND THE WHITE HOUSE AND CAPITOL. FOR THESE AREAS, 2013 IMAGERY WAS MERGED IN USING STREET CENTERLINES TO DEFINE THE 2013 MERGE AREAS TO MINIMIZE DISTORTION OF FEATURES. The project area covers the entire District of Columbia which is approximately 69 square miles. The digital imagery was used to create natural color digital orthophotography with 8cm pixel resolution. The final orthophotography deliverable products for this project consist of 328 ortho tiles at a scale of 1 to 2400. The tile dimensions are 800 meters by 800 meters. A corresponding MrSid image was created by mosaicking the 328 ortho tiles together and compressing the image using an 80 to 1 compression ration. This dataset provided as anArcGIS 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 mosaic raster dataset is available under additional options when viewing downloads. Requests for the individual GeoTIFF set of images should be sent toopen.data@dc.gov.
