Welcome to VDatum!
VDatum is a free software tool being developed jointly by NOAA'sNational 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.
Important:
- Understanding how the W.GOM Roadmap differs from the normal Roadmap
- Understanding how the Puerto Rico and US Virgin Island Roadmap differs from the normal Roadmap
- We retired the Raster Formats (GeoTIFF and ERDAS IMG) in the File Conversion.
- Understanding how the Columbia River Roadmap differs from the normal Roadmap
- Understanding how the West Coast Roadmap differs from the normal Roadmap
- Understanding how Chesapeake/Delaware Bay Transformation Roadmap differs from the normal roadmap
