Bare-earth GRID elevation data derived from a LIDAR. Grid elevation data derived from a LIDAR survey of Fire Island National Seashore (FIIS). LIDAR is a form of laser beach mapping which uses a pulsed laser ranging system mounted onboard an aircraft to take high density ground elevation measurements. This data is collected by NASA and sent to USGS for conversion to GeoTiff image files. It is then sent to NPS where it is converted into a grid for use in an ArcGIS software environment with elevation in each cell recorded in meters.
