The development of a hydrodynamic tidal model also allows the transformation of historical datasets to a common ellipsoidal datum. NOAA, USGS, and other partners have undertaken a pilot project in Tampa Bay, Florida, that has demonstrated both the complexity and the feasibility of generating a seamless bathymetric/topographic dataset (see Box 3.1). This project required the establishment of a fully calibrated hydrodynamic model for Tampa Bay and the development of a vertical datum transformation tool (Vdatum) that allows the easy transformation of elevations among as many as 26 orthometric, three-dimensional, or tidal datums. This pilot project has proven very successful and provides a clear indication of an optimum mechanism for producing seamless coastal charting products.
