A useful geo transformation tool for anyone that has a need to work with shoreline data and other hydrographic data products from NOAA and others. A useful transofrmation tool from NOAA – vDatum. VDatum is a free software tool being developed jointly by NOAA’s National Geodetic Survey (NGS), Office of Coast Survey (OCS), and Center for Operational Oceanographic Products and Services (CO-OPS). VDatum is designed to vertically transform geospatial data among a variety of tidal, orthometric and ellipsoidal vertical datums – allowing users to convert their data from different horizontal/vertical references into a common system and enabling the fusion of diverse geospatial data in desired reference levels.
