These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division using a Riegl VQ820G system. The data were acquired from 20160419 - 20160425. The data includes topobathy data in an LAS 1.2 format file classified as 1 - unclassified, 2 - ground, 7 - topo noise, 26 - bathymetric bottom or submerged topography, 27 - water surface, 28 - submerged object and 30 - International Hydrographic Organization (IHO) S-57 objects. A digital elevation model was then derived from the lidar points.

This lidar data are an ancillary product of NOAA's Coastal Mapping Program (CMP), created through a wider Integrated Ocean and Coastal Mapping initiative to increase support for multiple uses of the data. It is not intended for mapping, charting, or navigation. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne lidar.

Data include all lidar returns. Outliers or false returns (e.g., returns from birds, atmospheric particles, and/or system noise) may be present in the data. An automated ground classification algorithm was used to determine bare earth point classification. It should be noted that not all returns were correctly classified; therefore the user should examine for acceptability.

The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than plus or minus 1.0 m.; Quantitative Value: 1.0 meters, Test that produced the value: 2 Sigma
The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than plus or minus 0.15 m.; Quantitative Value: 0.15 meters, Test that produced the value: 1 Sigma
Data covers the 1620 tiles (500m x 500m tiles).

Data were processed to an initial LAS format using the Riegl RiProcess software. The Applanix POSPac software was utilized for GPS and inertial processing, and GeoCue, Terrasolid, and LP360 software for data visualization, 3D editing, and export to final LAS file. Data were processed in NAD83 horizontal and vertical datum.

The NOAA Office for Coastal Management (OCM) received files in las format. The files contained lidar elevation and intensity measurements of Key West, Florida. The data were in UTM Zone 17 coordinates and ellipsoid elevations in meters. The data classifications for the data are: 1 - unclassified, 2 - ground, 7 - topo noise, 26 - bathymetric bottom or submerged topography, 27 - water surface, 28 - submerged object and 30 - International Hydrographic Organization (IHO) S-57 objects. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Eliminated elevation outliers below -150 meters ellipsoid height; 2. Converted from UTM Zone 17 to geographic coordinates; 3. Sorted by gps time; 4. Reclassified data class 29 to 28; 5. Compressed the data using laszip.

The NOAA Office for Coastal Management used the point cloud data to derive a digital elevation model (DEM) for the area. The DEM was created by using the ground and bathy points processed through these steps: 1) reprojected to UTM zone 17 coordinates and orthometric heights via geoid12b; 2) retiled with a buffer using lastile from LAStools; 3) tiles rasterized with las2dem from LAStools; 4) tiles mosaiced into a single DEM with gdalbuildvrt and gdal_translate.
