Description:
Abstract: This OGC compliant Web Map Service includes a historical image data set of a mosaic of black and white photography of New Jersey from the early 1930s. The source imagery was hand cut to produce 261 mosaic tile prints on linen-backed paper. The data set was produced by scanning these mosaic tile prints at 400 dpi and saved as TIFF images. The scanned TIFF images had an approximate pixel resolution of 6.5 feet. They were georeferenced against 1995/97 color infrared digital orthophotography. The georeferenced TIFFs were clipped and merged into a single raster image for reference purposes only. The digital product has not been corrected for distortion or vertical displacement. They do not meet the National Standard for Spatial Data Accuracy (NSSDA). It is referenced to Geographic WGS 1984.
Purpose: For historical reference. For display on The National Map.
Supplemental Information: For information about the dataset in this map service, please consult its metadata record on NJGIN Explorer, the online geospatial catalog for New Jersey, at https://njgin.nj.gov/njgin. Go to the Enterprise Data tab and search for the title of the data set, which can be found in this metadata record, in the Entity Attribute section.

Data Quality Information:
Attribute Value Accuracy Information:
Attribute Accuracy Report: The accuracy of the imagery is variable. In some locations the imagery is within 10 feet and in others the features are more than 200 feet off. Although each tile had as many as 100 links used in the georeferencing process, the source imagery contained spatial errors uncorrectable through georeferencing.
Quantitative Attribute Accuracy Assessment:
Attribute Accuracy Explanation: The accuracy of the imagery is variable. In some locations the imagery is within 10 feet and in others the features are more than 200 feet off. Although each tile had as many as 100 links used in the georeferencing process, the source imagery contained spatial errors uncorrectable through georeferencing.
Logical Consistency Report: All paper image prints were scanned on the same Xerox 8825 scanner and processed in the same manner. Minimal overlap of tiles was used to produce the single mosaic. Since all tiles had different pixel sizes as a result of scanning, the average pixel size of 6.5 feet was used to create the single mosaic. This would produce minimal distortion of the source data. Gray shade tones were not adjusted and defaults used whenever applicable.
Completeness Report: Complete
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: Each scanned tiff was georeferenced to the 1995-97 DOQQ. RMS errors recorded during georeferencing ranged from 10.7 to 226.2 and are recorded in a image30_mask shapefile. The mean RMS is 80 feet and the standard deviation is 40.4 feet. 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.

Source Contribution: Paper prints were supplied by the NJ Department of Environmental Protection, NJ Forest Service and the Bureau of Tidelands.

Process Step:
Process Description: 
The air photos were flown for the State of New Jersey sometime in the early 1930s. The hundreds of individual photographs were hand cut, edgematched and labeled to produce the 261 photographic tiles used in this project. The majority of the linen backed tile prints were supplied by the NJ Forest Service. The 13 tiles missing from the collection were supplied by Bureau of Tidelands Management. The 261 tiles were scanned at 400 dpi by NJDEP/BGIS in 2004. The scanned tiff images were georeferenced to the 1995/97 DOQQ imagery. Link files were saved and RMS errors recorded. RMS errors recorded during georeferencing ranged from 10.7 to 226.2. Each georeferenced tiff image was then clipped with minimum overlap and converted to the ESRI GRID format. The 261 grids were mosaicked into a single grid with a 6.5 foot cell size.

Process Step:
Process Description: 
Image mosaic was imported from NJDEP server to server administered by NJ Office of Information Technology, Office of GIS, for use in web mapping applications. The mosaic was stored in Oracle/ArcSDE using lz77 compression. The tile size for storage in Oracle/ArcSDE was changed to 178x178 pixels, and the mosaic was repyramided using bilinear resampling. Image statistics were calculated, and the final product was analyzed to create database statistics.
