Hydrography Polygons 2015

This hydrography layer is comprised of surface water features identifiable in the orthoimagery and Lidar point cloud collected for Leon County, FL in the Spring of 2015. 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 2015 digital terrain model. Hydro_Poly represents rivers and streams wider than 10 feet and ponds and lakes larger than 0.2 acres. The Hydro_Lines represent rivers and streams less than 10 feet wide. TLCGIS regularly uses digital orthophotos and planimetric/hydrographic/topographic data to support regulatory functions, land management and acquisition, planning, engineering and habitat restoration projects. This dataset is part of a regularly scheduled update of LiDAR and digital orthophotography products. The dataset was created from source imagery acquired by a Trimble TAC80 natural color digital camera and LAS data acquired by a Optech ALTM HA500 (Pegasus) LIDAR sensor from January 18, 2015 to February 5, 2015.
