2022-2023 NOAA NGS Topobathy Lidar DEM: Coastal Maine

Published by National Geodetic Survey | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 23, 2026 | Last Modified: 2025-01-01T00:00:00.000+00:00
The NOAA Maine Topbathymetric Lidar was collected by NV5 using Leica Chiroptera Hawkeye 4X systems. The lidar acquisitions were flown between 20221006 and 20231216 in 120 missions. The final classified lidar data were then transformed from ellipsoid (GRS80) to geoidal height (Geoid18) and used to create topobathymetric DEMs in Cloud Optimized GeoTIFF format with 1m pixel resolution.
