Summary
This data release features a digitized historic shoreline for the New Jersey coastline (Point Pleasant, NJ to Longport, NJ) from 1971 to 1978. Imagery of the New Jersey coastline was acquired from the New Jersey Geographic Information Network (NJGIN) as two images: "1970 NJDEP Wetlands Basemap" (1971-78) and the "1977 Tidelands Basemaps" (1977-78). These images are available as a web mapping service (WMS) through the NJGIN website (https://njgin.state.nj.us/NJ_NJGINExplorer/jviewer.jsp?pg=wms_instruct). To reduce digitizing error, the imagery was acquired on a hard drive from the NJGIN via personal communication. Using ArcMap 10.3.1, the 1970 NJDEP Wetlands Basemap was used to delineate and digitize historical foreshore, backshore, mainland, and island shoreline positions, with the 1977 Tidelands Basemaps being used to fill in missing shorelines and clarify areas of uncertainty from the 1970s imagery. These shorelines were digitized for use in long-term shoreline and wetland analyses for Hurricane Sandy wetland physical change assessment.
