Document Info:

• Title: Ortho 2011
• Author: DCGIS
• Comments: 2011 Orthophoto - Orthoimagery data produced for the District of Columbia on December 28 and 29 of 2011. Due to P-56 area flight restrictions, several sensitive areas were not captured. These areas were filled in with our Ortho 2010. The project area for the 2011 project covers the entire District of Columbia and immediate surrounding area equaling approximately 80 square miles. A single corresponding MrSid image (mg3) was created by mosaicking the 328 ortho tiles together and compressing the image using an 15 to 1 compression ratio. All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters.
