CZMIL integrates a lidar sensor with simultaneous topographic and bathymetric capabilities, a digital camera and a hyperspectral imager on a single remote sensing platform for use in coastal mapping and charting activities. Native lidar data is not generally in a format accessible to most Geographic 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 imported into GIS software for visualization and further analysis. Horizontal positions, were provided in UTM Zone 17N NAD83 (2011), meters. Vertical positions were referenced to the NAD83 (2011) ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID18 model was used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88). The 3-D position data are sub-divided into a series of GeoTiff files, which are tiled into 1-km by 1-km boxes defined by the Military Grid Reference System. In addition to these bare earth Digital Elevation Model (DEM) data, the co-collected RGB imagery and the lidar point data that these DEM data were created from are also available from the NOAA Digital Coast. A link to the lidar point data is provided in the URL section of this metadata record. DEMs at a 1 meter grid spacing, created from all classifications, are available by request at coastal.info@noaa.gov.
