Description:"VDatum is a datum transformation software tool developed by NOS that provides conversions between tidal, orthometric, and ellipsoidal vertical reference frames. A VDatum application was created for Florida and the South Atlantic Bight, covering the U.S. coast from the north at Sapelo Island, Georgia, and to the south at Fort Lauderdale, Florida. The original application became operational in April 2010. Users at the Jacksonville, Florida, District of the U.S. Army Corps of Engineers found some apparent problems in the datum conversion data when they used VDatum to create gridded fields of the differences between NAVD 88 and MLLW for eastern Florida. Most of the problems were attributed to spurious tidal transformations over barrier islands. To remedy this problem it was decided to split the VDatum region for eastern Florida into two smaller regions, with an inner (western) and outer (eastern) region, each with a new bounding polygon. The border between the two regions would act to separate the inland waterways from the offshore region. Following standard procedures, new data files for the tidal datums and topography of the sea surface were generated for each new region and tested. The new version became operational in April 2012"--Abstract.
