Interferometric Data

The interferometric data for the Ebb Shoal and the River Inlet was grided at 20 meter spacing. Bathymetric data from the USACE LARC surveys were also imported within the x-y-z spreadsheet and gridded with the soundings collected by the interferometric system. The methodology for collection and processing of bathymetric data is described in the report: "BATHYMETRY OF THE CAPE FEAR RIVER EBB TIDAL DELTA, 2001-2002"
The data are in the following columnar format:
      Easting      Northing     Depth

The North Carolina state plane coordinates are referenced to the North Atlantic Datum of 1983 (NAD83). The vertical coordinates are referenced to the National Geodetic Vertical Datum of 1929 (NGVD29).
