NJDEP Bureau of GISThe Till Areas Overlaying Fluvial and Lacustrine Sediment in New Jersey geodatabase 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 layer contains polygons of till deposits overlying fluvial and lacustrine sediment.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/2b20eca00bd1407b8040d82bd8be4fa4_0engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicTill Areas Overlaying Fluvial and Lacustrine Sediment in New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2025-11-24
