Description: 0.6 meter contours. This dataset contains locations and attributes of 0.6 meter interval topography data, created using bare earth points from the lidar point cloud data.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.
Description: Digital Surface Model - 1m resolution. The dataset contains the 1m Digital Surface Model for the District of ColumbiaSome areas have limited data. The lidar dataset redaction was conducted under the guidance of the United States Secret Service. Except for classified ground points and classified water points, all lidar data returns and collected data were removed from the dataset within the United States Secret Service 1m redaction boundary generated for the 2017 orthophoto flight.
Description: The dataset contains hydro-breaklines that were collected in 2D as vector line work, using a combination of classified lidar dataset, intensity images, shaded relief TIN and contours.Some areas have limited data. The lidar dataset redaction was conducted under the guidance of the United States Secret Service. Except for classified ground points and classified water points, all lidar data returns and collected data were removed from the dataset within the United States Secret Service 1m redaction boundary generated for the 2017 orthophoto flight.
