VDatum is designed to vertically transform geospatial data among a variety of tidal, orthometric and ellipsoidal vertical datums - VDatum allows 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. completed Keown, Patrick 240-533-0031 1315 East West Hwy Silver Spring MD 20910-3282 patrick.keown@noaa.gov pointOfContact Keown, Patrick 240-533-0031 1315 East West Hwy Silver Spring MD 20910-3282 patrick.keown@noaa.gov custodian asNeeded Geodetic/Global Positioning theme NOS Data Explorer Topic Category Coordinate Systems DTL GEOID models GEOID03 GEOID06 (Alaska only) GEOID09 GEOID12A GEOID96 GEOID99 Geographic Horizontal Datums IGLD85 IGS00 IGS05 IGS08 IGS97 IGb00 ITRF ITRF2000 ITRF2005 ITRF2008 ITRF88 ITRF89 ITRF90 ITRF91 ITRF92 ITRF93 ITRF94 ITRF96 ITRF97 LMSL MHHW MHW MLLW MLW MTL NAD27 NAD83 NAD83 (1986) NAD83 (HARN) NAD83 serializations NAD83(MARP00) NAD83(PACP00) NAVD88 NEOS 90 NGVD29 Orthometric Datums PNEOS 90 SIO/MIT 92 State Plane Coordinates (SPC) Tidal Datums UTM Vertical Datums WGS84 WGS84 (G1150) WGS84 (G730) WGS84 (G873) WGS84 (transit) ellipsoidal datums geocentric (ECEF) theme DOC/NOAA/NOS/OCS > Office of Coast Survey, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
