Data Source


This Web Map Service (WMS) serves natural color imagery from the 2010 National Agriculture Imagery Program (NAIP) for New Jersey. 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 of ortho imagery within one year of acquisition.  NAIP quarter quads are formatted to the UTM coordinate system using NAD83. NAIP imagery may contain as much as 10% cloud cover per tile. Compressed county-wide mosaics were derived from the quarter quads. Compressed county-wide mosaics for NJ were acquired by the NJ Office of Information Technology and reprocessed to NAD83 NJ State Plane feet in lossless JPEG2000 format. In most client software, the default spatial reference system of the Web Map Service will be Geographic Coordinates, WGS84.

For imagery details, consult metadata records published by the USDA for the individual county mosaics. Publication dates for the counties are as follows: 2010-07-22 Mercer 2010-08-10 Atlantic, Burlington, Camden, Cape May, Monmouth, Ocean 2010-08-16 Bergen, Passaic, Warren 2010-09-23 Cumberland, Essex, Gloucester, Hudson, Hunterdon, Morris, Salem, Somerset, Sussex, Union 2011-06-01 Middlesex

Horizontal Position Accuracy

The source imagery used is 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). Because the WMS provides a resampled image, the accuracy of this image may be slightly poorer. This effect has not been examined in a quantitative manner.
