These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division using a Riegl VQ880G system. The data were acquired from 20170320-20170405. The data includes topobathy data in an LAS 1.2 format file with possible classifications as 1 - unclassified, 2 - ground, 7 - topo noise, 26 - bathymetric bottom or submerged topography, 27 - water surface, 29 - submerged object. This data set may also include lidar intensity values and encoded RGB image values.

| Abstract: |
These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division using a Riegl VQ880G system. The data were acquired from 20170320-20170405. The data includes topobathy data in an LAS 1.2 format file with possible classifications as 1 - unclassified, 2 - ground, 7 - topo noise, 26 - bathymetric bottom or submerged topography, 27 - water surface, 29 - submerged object. This data set may also include lidar intensity values and encoded RGB image values. |
| Purpose: |
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. |
| Supplemental Information: |
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. |

Process Steps
Process Step 1
| Description: |
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. |

Process Step 2
| Description: |
The NOAA Office for Coastal Management (OCM) received files in las format. The files contained lidar elevation and intensity measurements of Tabbs Creek, Virginia. The data were in UTM Zone 18 coordinates and ellipsoid elevations in meters. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Converted from UTM Zone 17 to geographic coordinates 2. Sorted by gps time 3. Compressed the data using laszip |
