Hydrography Polygons 2020

This hydrography polygon layer is comprised of surface water features identifiable in the orthoimagery and Lidar point cloud collected by USGS for the 2020 Hurricane Michael lidar project. The lidar data was acquired by a Riegl CQ-1560i lidar system on January 7, 2020 that was processed by Dewberry Engineers and provided by USGS. The delineation of the hydrographic features reflects the ground condition at the time of source data acquisition. Hydro_Poly and Hydro_Line are 2-D feature classes derived from the 3-D hydrographic breakline data used to complete the 2020 digital terrain model. Hydro_Poly represents rivers and streams wider than 8 feet and ponds and lakes larger than 0.2 acres. The Hydro_Lines represent rivers and streams less than 8 feet wide.
