Though CORPSCON offered integrated NGS products long before NCAT it has always been under the control of USACE.Īlthough NGS is not aware of any issues with CORPSCON integrating NGS products and services, Army Corps of Engineers product, not an NGS product. Is the web-based NCAT tool a replacement for Corpscon 6? For the interim, to compute an NAVD 88 orthometric height from an NAD 83 (2011) ellipsoid height please use the The current version of NCAT does not support conversions between ellipsoid and orthometric height, but future versions will. NGS recommends Chrome for the best user experience.ĭoes NCAT convert between ellipsoid and orthometric heights? While NCAT works on all browsers, legacy versions of IE have known issues. The engine that powers NCAT, known as ncat-lib, is publicly available on Where can I access the source code for NCAT? The tool does generate results in both decimal degrees and degrees-minutes-seconds You can find tutorial videos at and click on the Tutorial & FAQ's tab.Ĭould I get the coordinate conversion tool to give me lat/lon in degrees-minutes-seconds instead of decimals of a degree? Is there a simple tutorial (or YouTube demo) on how to use the NGS Coordinate Conversion and Transformation Tool (NCAT)? Please keep an eye out for news or product update announcements on our website. Will NCAT convert today's data to the modernized NSRS (NATRF2022, NAPGD2022, etc.), once fully implemented? You should see transformed height under "Transformed Coordinate". Pick NGVD 29 from the dropdown and click submit. Towards the bottom of the screen you see an option to choose an input geopotential or vertical datum. Enter your latitude, longitude and orthometric height. Once the page comes up, please select horizontal+height from the top row. How can I convert an elevation measurement for my home based on mean sea level datum from 1929 to reflect a more recent datum? Please be sure to choose the horizontal+height option and enter a height. Is there something special that I have to do to get it to work?Īn ellipsoid height is needed for combined scale factor computation. I expect the NCAT output to have a combined scale factor, but it is missing. If you notice any discrepancies, please let us know. NCAT and VDatum share the same codebase and the results should be consistent between them. No, there is no batch mode for web service.Īre the results from NCAT and VDatum the same? Is there a batch mode for the Web service or plans to implement one? Future versions of NCAT may support WGS84. If I have records from all over the world then which NAD 83 do I use in place of WGS84?įor now, you may use HTDP to transform WGS84 to NAD 83 first and use the transformed NAD 83 coordinates in NCAT. WGS84 is not an option in the conversion tool. What is the maximum file size that can be submitted to multipoint conversion?.Surprisingly, the name Las Vegas is often applied to unincorporated areas surrounding the city, more specifically the resort areas on and near the Las Vegas Strip.
