Description

This service provides access to a raster dataset containing scanned and georeferenced black and white aerial photographs of the Atlantic coast of New Jersey. Photograph date is believed to be 1920, based upon hand-written notation on some of the storage envelopes. In addition, photo 012 shows Turtle Gut Inlet to be open, and the inlet closed naturally in 1921. Source of original images: photographic archives of the Beach Erosion Board (predecessor of the former Coastal Engineering Research Center), presently stored at the Coastal and Hydraulics Laboratory, Engineer Research and Development Center, in Vicksburg, Mississippi, USA. Original image condition: variable. These prints look like they were made quickly because many of the negatives are crooked on the photographic paper. Most are low contrast and show fading and discoloration. Printed on single-weight glossy paper. The printing date is unknown.

Horizontal Positional Accuracy

All images were georeferenced by the NJDEP comparing known control points in imagery to 1930s Aerial Photography of New Jersey Web Map Service, NJDEP 1977 Tidal Wetlands Basemaps Web Map Service, New Jersey 2002 High Resolution Orthophotography, and New Jersey 2012 High Resolution Orthophotography, Natural Color Map Service imagery, all published by the NJ Office of Information Technology, Office of GIS (NJOGIS). RMS error values of georeferenced images were documented on 174 of the 179 total images. Values ranged from 2.16 to 38.40 with an average of 8.10. No positional testing was done by BGIS. This imagery does not meet national map accuracy standards, nor should it be used as a base for mapping.
