Data coverage generally extends along the shoreline 500 meters onshore, to 1000 meters offshore from the waterline. The VQ-480 sensor has a pulse repetition rate of 150 kHz at near infrared laser wavelength. Native lidar data are not generally in a format accessible to most Geographical Information Systems (GIS). Specialized in-house and commercial software packages are used to process the native lidar data into 3-dimensional positions that can be exported to standard formats and imported into GIS software for visualization and further analysis. Horizontal positions, provided in geographic coordinates in meters, are referenced to the NAD83 (2011) Epoch 2010 datum. Vertical elevations in meters are also referenced to IGLD85. Data Available from NOAA Digital Coast Data Access Viewer: In addition to these bare earth Digital Elevation Model (DEM) data, the lidar point data that these DEM data were created from are also available. These data are available for custom download at the link provided in the URL section of this metadata record.
