NOAA/NOS's VDatum 4.7: Vertical Datums Transformation
VDatum by NOAA lets you convert geospatial data between different vertical datums, making it easy to unify coastal and mapping data for your projects.
Convert geospatial data across vertical datums
VDatum is a free software tool from NOAA that helps you convert geospatial data between different vertical datums. Whether you’re working with tidal, orthometric, or ellipsoidal references, you can easily transform your data to a common system, which is especially useful for coastal mapping and scientific research.
This tool is designed for anyone who needs to unify geospatial information from multiple sources, such as surveyors, GIS professionals, and researchers. By making these conversions simple, VDatum supports more accurate mapping, data analysis, and the integration of diverse datasets for a wide range of projects.
With VDatum, you can save time and reduce errors when preparing your geospatial data, ensuring your work is consistent and reliable across various applications.
