Bathymetry for the Santee River was derived from two surveys containing11,079 soundings. No surveys were omitted. The average separationbetween soundings was 40 meters. Both surveys dated from 1934. The totalrange of sounding data was 0.3 meters to -10.4 meters at mean low water.Mean high water values between 1.2 and 1.4 meters were assigned to theshoreline. One point was found that was not consistent with the surroundingdata, and was removed prior to tinning. DEM grid values outside theshoreline (on land) were assigned null values (-32676).The Santee River has four 7.5 minute DEMs and a single one degreeDEM. The 1 degree DEMs were generated from the higher resolution 7.5minute DEMs which covered the estuary. A Digital Elevation Model(DEM) contains a series of elevations ordered from south to northwith the order of the columns from west to east. The DEM isformatted as one ASCII header record (A- record), followed by aseries of profile records (B- records) each of which include a shortB-record header followed by a series of ASCII integer elevations(typically in units of 1 centimeter) per each profile. The lastphysical record of the DEM is an accuracy record (C-record).The 7.5-minute DEM (30- by 30-m data spacing) is cast on theUniversal Transverse Mercator (UTM) projection. It provides coveragein 7.5- by 7.5-minute blocks. Each product provides the samecoverage as a standard USGS 7.5-minute quadrangle but the DEMcontains over edge data. Coverage is available for many estuaries ofthe contiguous United States but is not complete.
