Overview
Lidar digital elevation model generated for a location in coastal Delaware
Many different partners and groups, and several Center-led data projects, have contributed to the lidar data collection housed and distributed by the NOAA Coastal Services Center. The data span more than a decade and were collected using several different sensors. The collection includes data from topographic and bathymetric lidar sensors.
Data are available for all of the coastal states and range from shoreline strips to full county coverage. The products have been delivered to the Center in various formats, projections, datums, and units. Once received, the data are reviewed, checked for errors, and standardized in a single format, projection, and datum.
