2018 LiDAR - Normalized Digital Surface Model - Tiles

Normalised Digital Surface Model - 1m resolution. The dataset contains the Normalised Digital Surface Model for the Washington Area.Voids exist in the data due to data redaction conducted under the guidance of the United States Secret Service. All lidar data returns and collected data were removed from the dataset based on the redaction footprint shapefile generated in 2017.
