Software Tool VDatum, Version 4.0, is Released

Friday August 16, 2019

NOS is developing an innovative and evolving software tool called Vertical Datum Transformation, also known as VDatum. Free to the public, VDatum's primary purpose is to convert elevation data from various sources into a common height reference system. Without a common reference system, creating maps and charts from different data sources can introduce inconsistencies. In coastal areas, a shift in elevation on a gently sloping beach might change the overall shoreline delineation, or influence inundation mapping. VDatum coverage is currently complete in all coastal regions of the continental United States, Puerto Rico, and the U.S. Virgin Islands. A Southeast Alaska Regional Model was added in 2019, and future coverage for Hawaii, Alaska, and the Pacific territories will begin after obtaining geodetic and tidal observations.
