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.</div><div><br /></div><div>Raster Cell Size: 2.5 foot</div><div>Required Vertical Accuracy: The required NVA is: 19.6 cm (0.64 ft)at a 95% confidence level</div> |
