My colleague, Kevin, and I are already signed up–we moved our team meeting so it wouldn’t conflict.
I’m just one of those evil GIS people. Bwah-hah-hah! Seriously, I do coordinate systems and transformations at Esri.REMINDER. Webinar is today, 9 June 2022, at 1400 Eastern time.
NATRF by mid ’25, along with the most important tools. Some tools may not be released until much later. Coordinates will be reported in terms of “Survey Epoch Coordinates” and “Reference Epoch Coordinates”. ie/ where the point is right now and where it was at some point in time in the past.
In California (west coast in general, plus Alaska) epoch dates are critical. There are areas in the SF Bay Area that are moving northwesterly at almost 6cm/year and quite differentially (in rate) over relatively short distances. Although not really employed, there is almost a need for epoch date heights in the San Joaquin Valley where some areas are subsiding about a foot/year.

I swear the mileage shown in this graphic is much longer. Must be because I’m thinking drive time 🙂

The Pacific NW is moving at much the same rate but without the differential, locally.
