1ft Elevation Contours

资源简介：
The terrain dataset and contours were created using aerial Lidar collected on March 25, 2022 at a density of greater than 12 points per square meter. Lidar points classified as ground were used as the basis of the terrain model. Breaklines were added around bridges, retaining walls, and other sharp features to improve the accuracy around sudden breaks in the terrain. Breaklines were also added along significant bodies of water to assist with hydro-enforcement. The final terrain dataset was used to generate 1-foot contours. RMSEz = 0.33 feet.
