 "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, following classifications in accordance with project specifications and the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards. The NOAA Hurricane Irma Project data includes all LiDAR returns. An automated grounding classification algorithm was used to determine bare earth and submerged topography point classification. The automated grounding was followed with manual editing. Submerged topography elevations were adjusted to correct for sensor depth bias on a per sensor basis using NOAA provided ground truth data. Intensity values of bathymetric bottom returns were normalized for water depth. Total propagated uncertainty (TPU) values were calculated for the bathymetry data. The full workflow used for this project will be documented in the NOAA Hurricane Irma final technical report, provided upon project completion.This layer has a resolution of 2m in order to speed up display speeds, a 1m version is available upon request.",
