2019 Digital Elevation Model

These are Digital Elevation Model (DEM) data for Sarasota county,as part of the required deliverables for the FL Peninsular FDEM 2018 D19 DRRA Lidar project. Class 2 (ground) lidar points in conjunction with the hydro breaklines were used to create a 2.5 foot hydro-flattened Raster DEM. Dataset Description: FL Peninsular FDEM 2018 D19 DRRA Lidar project called for the Planning, Acquisition, processing and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.35 meter. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.3. The data was developed based on a horizontal projection/datum of NAD83 (2011), State Plane, U.S Survey Feet and vertical datum of NAVD88 (GEOID12B), U.S Survey Feet. Sarasota County GIS has subsequently re-projected the data to NAD83 State Plane HARN, U.S. Survey Feet. Raster Cell Size: 2.5 foot Required Vertical Accuracy: The required NVA is: 19.6 cm (0.64 ft)at a 95% confidence level
