Service Description:

2015 Orthophoto - This document describes the processes used to create the orthoimagery data produced for the District of Columbia from 2015 digital aerial photography.  It was flown in mid to Late April, completed on April 24, 2015.

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. All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters.
