Spot Elevations 2020

This layer displays spot elevations for Tallahassee and Leon County Florida. Spot elevations display the actual elevation of a selected point on the ground. The features displayed in this layer depict ground conditions at the time the source lidar was acquired. The source DEM used to derive this layer is a LIDAR Digital Elevation Model (DEM) that was generated from 2020 Hurricane Michael LiDAR data. The LiDAR data was acquired by a Riegl CQ-1560i LiDAR system on January 7, 2020. This acquisition was part of a USGS flyover of areas affected by Hurricane Michael, including Leon County. TLCGIS contracted Dewberry Engineers to process the lidar results for Leon County. The source DEM is derived from classified LiDAR ground points and breaklines. The DEM has a 2.5 ft grid structure.
