New Geodetic Videos on YouTube
The Florida Geomatics Users Group (formerly the FL GPS Users Group) has posted a short series of 1-hr videos on geodetic surfaces, horizontal and vertical datums and the 2022 datums that were done by Dave Doyle and Dave Newcomer (former NGS FL geodetic advisor). Their effort was to make these presentations easily available to any and all.
