Geospatial data for bedrock elevation and overburden thickness maps of the Five Boroughs, New York City, New York

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 08:34 PM | Dataset Last Updated: May 25, 2023 at 12:00 AM
Using a combination of public and proprietary historical construction test borings, recent exploration drilling, USGS observation wells, outcrops, and seismic measurements, a series of geospatial overlays for bedrock elevation and overburden thickness were created for the Five Boroughs of New York City, New York. Rasters were interpolated from a point elevation data set and refined using published and interpretive bedrock contours, and interpreted glacial valleys and faults. Contours for bedrock elevation were generated at 100-ft contour intervals and smoothed. This data release includes shapefiles containing the input point elevation features and output contours, and rasters of interpolated bedrock elevation and overburden thickness surfaces.
