Geologic-unit contacts for the central third of the baqfr250 coverage were compiled by scanning mylar separates of the U.S. Geological Survey central bedrock sheet and the N.J. Geological Survey Open-File Map OFM-3 using a CalComp ScanPlus II scanner set at 400 dpi resolution. The scanner accuracy is +/-.25%. The images were saved using a TIFF 5.0 image format. The images were center-line traced into a vector format using CADCore Version 2.0 raster-to-vector conversion software. The vector lines were saved as ARC/INFO generate files with a line format. These line coverages were then generated and edited as ARC/INFO GIS polygon coverages in board inches. Proof plots were made of each coverage on mylar and compared to the original base maps. Any line that deviated from the original position by more than .012 in. (about 1 to 1.5 line widths) were re-digitized, re-plotted, and corrected until the desired results were obtained. CalComp 9100 and 9500 digitizers were used for editing. The coverages were then transformed into NAD27 SPC feet using corner points of 7-1/2 minute quadrangles for the transformation links. RMS registration errors from the transformation process were less than .006. Coverages were projected into NAD83 SPC feet after final map editing.
The bedrock coverages were appended into a single coverage and edited to remove non-essential boundary lines. Polygon labels for the baqfr250 coverage were then added and updated. Geonum item values for each polygon were used for combining lithologic units into aquifer units using the ARC/INFO dissolve function. Any polygons less than 1,000,000 square feet in area were selected and deleted.
