OK, so some rinex files are dos (carriage return and line feed at the end of each line) and some rinex files are unix (only line feed at the end of ea...

Each epoch has a header with time and date and SV numbers (and how many satellites). Then range and phase measurements from each satellite (often on t...

Also look into an intuicom rtk bridge. It helps a lot

Not an EDM shot, but in 1878 the USC&GS observed a triangulation line of 192 miles, sighting a heliotrope on Mt Helena from Mt Shasta in Californi...

You have to tell the level the shots are inverted. It will not read it inverted unless that function is enabled. Once it is enabled, it will not read ...

I just bought a TSC3, because my last TSC2 died (pretty much, still works but the screen is not working totally). I knew there was a new Trimble data ...

I had to do a lot of photo control in southern Florida, sometimes in swamps and marshes. Low altitude stuff, 20 scale maps, 0.5' contours. I set two b...

You hit the nail on the head, Loyal. I was an idiot. After I had to pay for it a few times I learned. For whatever reason they did not use lanyards or...

Wild T2. Learned by doing 8 sets of triangulation angles over and over on dam deformation surveys. Then moved to a K & E transit, took some gettin...

In the past I expressed my opinion that it would be great to have elevations shown on boundary monuments (where available) to determine how deep to di...

Which brings up a question in my mind. If I have a LONG boundary line that has a very BIG difference in elevation, WHICH horizontal ground distance do...

I have seen a lot of USACE boundary maps (sometimes covering large areas around a reservoir) on which everything is SPC, bearings and distances. And a...

I think it is a sad reflection on our profession that some do not know the difference between so called "true" north and grid north, or between grid a...

Wonder what he means by "a bunch". Some of the automated monitoring setups have 40 or more total stations installed.

Thanks, Gene. Nothing like knowing the lingo to make me look smarter than I really am.I kinda like LR Day's idea to let gravity do the plumbing for me...
