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.
