GNSS Derived Heights Webinar

[DaveD]

Below is a note that was just posted at NGS this morning. It allows you access to a Webinar about the development of heights using Global Navigation Satellite System (GNSS) technology (e.g. GPS, GLONASS, Galileo etc.) The program was given in two 4-hours sesssions, this is the first one. Some parts may be more technical than you care for, but it does have some good background on datums and monumentation that some of you may find interesting.

Thanks, Dave. I watched the whole thing and found it interesting and informative. I also learned how to correctly pronounce some acronyms and words that I have been mentally mispronouncing.

Thankyouverymuch.

 

So .. if you can find a bench mark that has a NAVD 88 height equal to (and opposite) the GEOID height then the mark is ON the ellipsoid?.. cool, there is one in the county, I've never stood on a mathematical construct before.
