Jan 29, 2020 · NGS Coordinate Conversion and Transformation Tool (NCAT) allows users to easily convert between different coordinate systems and/or transform between different reference frames and/or datums, in a single step. For coordinate conversion, NCAT allows conversion between lat/long/height, SPC, UTM, XYZ, and USNG systems.
Vertical Datum Transformation, or VDatum, is a tool that converts elevation data from various sources into a common reference system. It is developed jointly by NOAA's National Geodetic Survey, the Office of Coast Survey, and the Center for Operational Oceanographic Products and Services. In support of the VDatum tool, Coast Survey develops ...

Mar 28, 2024 · Towards the bottom of the screen you see an option to choose an input geopotential or vertical datum. Pick NGVD 29 from the dropdown and click submit. You should see transformed height under "Transformed Coordinate". Will NCAT convert today's data to the modernized NSRS (NATRF2022, NAPGD2022, etc.), once fully implemented? Yes, it will.
A vertical datum is a surface of zero elevation to which heights of various points are referenced. Traditionally, vertical datums have used classical survey methods to measure height differences (i.e. geodetic leveling) to best fit the surface of the earth. The current vertical datum for the contiguous United States and Alaska is the North ...

Datum conversions from the National Geodetic Vertical Datum of 1929 to the North American Vertical Datum of 1988 among inland and coastal gages throughout the hydrologic regions of New England, the Mid-Atlantic, and the South Atlantic-Gulf have implications among river and storm surge forecasting, general commerce, and water-control operations.
