Digital Surface Model - 1m resolution. The dataset contains the 1m 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.
1 m resolution DSM from lidar flown on April 5, 2018. This data is used for the planning and management of Washington, D.C. by local government agencies.

The DSM was generated using all first return and only return points with the noise points excluded. The points were run through a Fugro proprietary software to generate a surface model at the required 1 m resolution. The hydro breaklines used in the DTM were burned into the DSM with the bridges and piers masked out of the water polygons so they remained in the final deliverable surface.

The lidar acquisition was flown in a single lift on April 5, 2018, at an altitude of 9,700 feet above mean sea level and composed of 24 flight lines, 22 primary lines and two cross ties. All lidar data was collected with a Piper Navajo PA31-50 and a Leica ALS80 lidar sensor, #133. Due to the known difficulties flying over DC, the ALS80 sensor was selected to take advantage of its flight altitude and speed, minimizing the number of lifts for the various flight restrictions. All lidar was collected in conjunction with airborne GPS.
