@leegreen Makes sense that they are using the same stations, as RTKData also claims about 20K stations. My problem with Geodnet when I tested it was t...

@mightymoe If you take the RTX ITRF current epoch coordinate and run it through HTDP you will get the (AFAIK) transformation that OPUS is doing.

OPUS (and RTX) return ITRF2020 at the current epoch. The ".6928" is a fraction of a year. I maintain that 2 (or maybe 3) decimals is sufficient to def...

I did some testing over the weekend, I connected to the service, it very quickly initialized, and I output GGA at 1s for a few days. I still need to a...

Glad that you enjoyed it, Wendell. I grew up on the Allegheny River, swimming in it in the summer. In the past it was very much an industrial city, sm...

Over the years I have tried to tie in some of the triangulation stations, and have computed local transformations to NAD83. The system was tied to sev...

@wendell The 20th I may be around

The OP said it was a digital level. There is still the problem of writing down something different than what the level displays, like transposing digi...

I have seen a lot of digital level users record all of the data in a field book and then manually enter it into a spreadsheet or manually compute it. ...
