The National Agriculture Imagery Program (NAIP) acquires aerial imagery during the agricultural growing seasons in the continental U.S. A primary goal of the NAIP program is to make digital ortho photography available to governmental agencies and the public within a year of acquisition. This four-band imagery was collected in 2011, and was originally published in October of 2011 . It was made available from the West Virginia GIS Tech Center in April of 2012.

All data was delivered with 1-meter Ground Sample Distance (GSD). The imagery is rectified to a horizontal accuracy of within +/- 5 meters of reference digital ortho quarter quads from the National Digital Ortho Program.

The dataset can be downloaded by digital orthophoto quarter quads (DOQQ). The data is compressed into MrSid format, with a compression ratio of 10:1 . Files range from 13 to 16 MB. MrSid format images are 3 band and, as a result a separate dataset for color infrared and natural color was created.

Uncompressed 4 band .tif files are available as well, but due to the size (~320 GB) of this dataset, interested parties will need to provide a hard drive to the WVGISTC. There is a small fee associated with this service. Contact Frank Lafone for more information.
