Transformation Uncertainties in the ‘Louisiana/Mississippi - Eastern Louisiana to Mississippi Sound’ Regional Model, have been found to range from 20 to 50 cm in particular locations from the Mississippi River Delta north to Lake Pontchartrain. Users should understand there is higher uncertainty (greater than 50 cm) than reported when transforming to tidal datums in the vicinity. Gulf of Maine (identified issue): a transformation error in ME grids for VDatum in the vicinity of Bath ME has been identified.

The full VDatum API should have all the functionality as the VDatum Tidal API and more.
The full VDatum API will be transitioned from beta to production. 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. 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).
