USGS Color Topographic Maps of New Jersey (7.5 Minute)
NJ Office of Information Technology (NJOIT), Office of Geographic Information Systems (OGIS)
This Web Map Service (WMS) layer serves a seamless copy of Digital Raster Graphics (DRG) of U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps. Original DRG’S supplied by the U.S. Geological Survey were reprocessed by removing the collar information and reprojecting into NAD83 NJ State Plane Feet. Each raster entity or pixel contains a color index from 0 through 12 referencing a color palette of RGB values from 0 through 255 in which the standard colors used in the DRG are defined.In most client software, the default spatial reference system of the service will be Geographic Coordinates, WGS84.
The DRG’s were produced through an Innovative Partnership agreement between The Land Information Technology Company, Ltd., of Aurora, CO and the USGS. Further information about the DRG’s is available at http://topomaps.usgs.gov/drg/Additional processing of the DRG’s was performed by the N.J. Department of Environmental Protection, Bureau of GIS.
Processing of Digital Raster Graphics to create a seamless image layer originally was performed by NJ Department of Environmental Protection, Bureau of GIS.
Acknowledgment of the USGS as the data source, and NJ Office of Information Techology (NJOIT), Office of Geographic Systems (OGIS) as the service provider, would be appreciated in products derived from these data.
