The data includes topographic data in an LAS format file. The NOAA Office for Coastal Management (OCM) processed the data to bare earth (class 2) and water points classified (class 9). An automated filter was used, followed by semi-manual classification and bridge removal. Original contact information: Contact Org: National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), National Geodetic Survey (NGS), Remote Sensing Division Title: Chief, Remote Sensing Division Phone: 301-713-2663 This lidar was acquired by the NOAA Remote Sensing Division to support NOAA's IOCM (Integrated Ocean and Coastal Mapping) initiative. 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.

The RMSE = 13.0 cm in open terrain based on 10 points. Completeness Report Not applicable Conceptual Consistency Not applicable Data were processed to an initial LAS format using the ALTM DASHMAP software. The Applanix POSPac software was utilized for GPS and inertial processing, and Terrasolid software for data visualization, 3D editing and export to final LAS file. Data were processed in NAD83 horizontal and vertical datum. 2008-06-17T00:00:00 National Geodetic Survey processor The NOAA Office for Coastal Management (OCM) received files in LAS format. The files contained LiDAR intensity and elevation measurements. OCM performed the following processing on the data to make it available within the LiDAR Data Retrieval Tool (LDART): 1. The data were converted from UTM coordinates to geographic coordinates. 2. The LAS header fields were sorted by latitude and updated. 3. The data was filtered to eliminate outliers. 2008-08-04T00:00:00 Lidar data were processed to bare earth (class 2) and water points classified (class 9). An automated filter was used followed by semi-manual classification and bridge removal. 2008-09-12T00:00:00 Acquisition and Processing National Geodetic Survey originator
