Description

Data set contains reprocessed digital orthophotography based on Digital Ortho Quarter Quads (DOQQ) derived from the National Aerial Photography Program (NAPP). The original DOQQs were completed under the federal DOQQ program with state representation by NYS DEC. A digital orthophoto is a raster image of remotely sensed data in which displacement in the image due to sensor orientation and terrain relief have been removed. Digital orthophotos combine the image characteristics of a photograph with the geometric qualities of a map. The digital orthophotos in this series have a 1 meter pixel ground resolution. The data set presents information that represents current conditions for New York State from 1994 – 1998. The coverage includes New York State and extends to parts of New Jersey, Pennsylvania, Vermont, and Canada.
