2018 LiDAR - Normalized Digital Surface Model

Normalized Digital Surface Model - 1m resolution. The dataset contains the Normalized 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. This dataset provided as an ArcGIS Image service. Please note, the download feature for this image service in Open Data DC provides a compressed PNG, JPEG or TIFF. The compressed GeoTIFF raster dataset is available under additional options when viewing downloads.
