A Southeast Alaska regional model was added in 2019, and future development of coverage for Hawaii, Alaska, and the Pacific territories will commence once foundational geodetic and tidal data are established to allow for valid model construction. (including the Great Lakes), Puerto Rico, and the U.S.
VDatum coverage is complete in all coastal regions of the continental U.S. VDatum's capabilities to transform and fuse diverse elevation data benefits coastal applications including inundation modeling (e.g., storm surge, tsunami, sea level rise impacts), ecosystem management and coastal planning, hydrographic surveying using Kinematic GPS for vertical referencing, and shoreline delineation from LIDAR data. In a coastal area, for example, a shift in elevation on a gently sloping beach may change the overall depiction of the shoreline or results of inundation mapping. Free to the public, VDatum's primary purpose is to convert elevation data from various sources into a common reference system.Ī common reference system is important because irregularities can occur when maps and charts are created from different data sources.

VDatum stands for Vertical Datum Transformation, an innovative and evolving software tool under development by NOAA's National Ocean Service.
