2018-2019 NOAA NGS Topobathy Lidar DEM Hurricane Irma: Miami to Marquesas Keys, FL
The NOAA Hurricane Irma Project area data were collected by Quantum Spatial, Inc. (QSI) using three Riegl systems: a Riegl VQ-880-G+, a Riegl VQ-880-GII, and a Riegl VQ-880-GH. The project acquisition dates spanned from 20181120-20190323 in 85 missions. The final classified LiDAR data were transformed from WGS80 ellipsoid elevations to Geoid12b orthometric elevations and were then used to create topobathymetric bare earth digital elevation models (DEMs) in ERDAS Imagine (*.img) format with a 1m pixel resolution. Ground (2), bathymetric bottom (40), and submerged objects (43) classified points were used in the bare earth DEM creation. The NOAA Hurricane Irma Project digital elevation model (DEM) dataset consists of a bathymetric void clipped bare earth model and an interpolated bare earth model. The 100 meter buffered project area consists of approximately 1,381,270 acres and stretches from the eastern coast of Miami south and westward to the Marquesas Keys. DEM files were compiled in 5,000 m x 5,000 m tiles and clipped to the project boundary. The full project dataset is comprised of 300 - 5,000 m x 5,000 m DEM tiles.
