2018-2019 NOAA NGS Topobathy Lidar Hurricane Irma: Miami to Marquesas Keys, FL

Description

The NOAA Hurricane Irma Supplemental Topobathymetric LiDAR 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 NOAA Hurricane Irma project acquisition dates spanned from 20181120-20190323 in 85 missions. This project dataset includes topobathymetric data in a LAS format 1.4, point data record format 6, with the following classifications in accordance with project specifications and the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards: 1 - unclassified 2 - ground 7 - noise 40 - bathymetric bottom or submerged topography 41 - water surface 43 - submerged feature 45 - water column 46 - overlap bathy bottom - temporally different from a separate lift 71 - unclassified associated with areas of overlap bathy bottom/temporal bathymetric differences 72 - ground associated with areas of overlap bathy bottom/temporal bathymetric differences 81 - water surface associated with areas of overlap bathy bottom/temporal bathymetric differences 85 - water column associated with areas of overlap bathy bottom/temporal bathymetric differences 1 Overlap - edge clip Please note that classifications 46,71,72,81, and 85 associated with temporal bathymetric differences have only undergone automated classification and have not been manually reviewed. This data set also includes LiDAR intensity values, number of returns, return number, time, and scan angle. 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. LAS files were compiled in 500 m x 500 m tiles. This complete project dataset is comprised of 23,926 - 500 m x 500 m LAS tiles.
