Process Description:
The USGS created the layouts for the Miscellaneous Investigations Series maps using Adobe Illustrator. The three layouts containing surficial polygons and registration tics were modified extensively and the exported utilizing Avenza's MAPublisher software. The resulting ESRI shapefiles of northern, central and southern New Jersey were then converted to ESRI coverage file format. The coverage files were then transformed into files utilizing the North American Datum of 1983, New Jersey State Plane coordinate feet. A root-mean-square error of 0.005 was obtained for each file. A digitizing tablet was used to correct errors and to add new and revised data (polygons) to the files. An RMS of 0.005 was maintained. Attribution of the polygons was performed interactively after digitizing was completed. The coverages were then edge-matched and joined together. The coverages were then converted to ESRI's shapefile format.
