NJDEP Bureau of GISThe Glacial Sediments in New Jersey layer is a Geographic Information Systems (GIS) geodatabase layer compiled from NJGS Open-File Map No. 3, Hydrogeologic Character and Thickness of the Glacial Sediment of New Jersey, 1990 (revised 2002). The layer details the map distribution, thickness, and types of Quaternary glacial sediment in northern New Jersey at the 1:100,000 scale. The GIS data are compiled in NAD83 State-Plane-Coordinate feet using an optical scanner, raster-to-vector conversion software, and a digitizer. This "sediment" layer contains polygons of stratigraphic units.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/36f4415e59a242c6b81334874d9b380f_0engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicGlacial Sediments in New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2025-11-24
