Hydrography Lines 2022

This hydrography lines or hydro lines 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 Polygon 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 Polygon 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. While the 2020 Lidar was initially used to generate this layer, 2022 imagery was used to update breaklines in areas of new development. That is why this layer is referred to as 2022.
