Title
National Agriculture Imagery Program (NAIP) for West Virginia - County Mosaics {2009}
Description
This data set contains imagery from the National Agriculture
Imagery Program (NAIP). NAIP acquires digital ortho imagery
during the agricultural growing seasons in the continental U.S..
A primary goal of the NAIP program is to enable availability of
ortho imagery within one year of acquisition. NAIP provides two
main products: 1 meter ground sample distance (GSD) ortho
imagery rectified to a horizontal accuracy of within +/- 5
meters of reference digital ortho quarter quads (DOQQ's) from
the National Digital Ortho Program (NDOP) or from the
National Agriculture Imagery Program (NAIP); 1 meter GSD ortho
imagery rectified to within +/- 6 meters to true ground.
The tiling format of NAIP imagery is based on a 3.75' x 3.75'
quarter quadrangle with a 300 meter buffer on all four sides.
NAIP quarter quads are formatted to the UTM coordinate system
using NAD83. NAIP imagery may contain as much as 10% cloud
cover per tile. This file was generated by compressing NAIP
quarter quadrangle tiles that cover a county. Two types of
compression may be used for 2008 NAIP imagery: MrSID and JPEG
2000. Target values for the compression ratio are (15:1).
