2005 Orthophoto - This document describes the processes used to update the planimetric and topographic data originally produced for the District of Columbia from the 2005 aerial photography. 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 15cm 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.
