Comments:
The DEM files are 32-bit floating point, 1-meter (m) horizontal resolution IMG files. Both the DEM and LAS files are in meters, North American Datum 1983, Universal Transverse Mercator zone 15 North or 16 North, North American Vertical Datum 1988, geoid 2012 (NAD83, UTM zone 15N or 16N, NAVD88, GEOID12a). The data near the border of UTM zones 15 and 16 (Port Fourchon, Elmers, Grand and Grand Terre regions in Louisiana) have been projected into both zones for convenience. Vertical datum transformation can be made using VDatum.
