Delving into the raw data I see what happened, though I don't know why: when I shot 15 during the resection, the DC recorded the direct reading as re...
Maybe the MS60 has more power than my GeoMax, but on a 100°F day the GMP101 gets lost in the shimmer at half a mile, while the GPR1 will still return ...
I don't know if your agency is cost-sensitive, but I have a genuine Leica GRZ4 that I'd let go for less than that difference. I got it in like-new co...
Right now I believe he's recovering from heart surgery. He's somewhat active on Facebook.
In my part of the world, that PLS 100 years in the future will find that my plat coordinates are about 6 feet off.
Back in *my* early days we used to set up on the centerline of a railroad track and use the miles-long tangent for meridian. I always hated standing ...
I imagine that a good percentage of those handles got put aside when the guns were outfitted with EDM mounts, and subsequently got separated from the ...
As far as the Javad Triumph-LS goes, the converter is built into the J-Field software; just export as Star*Net vectors and you get a .gps file. If yo...
Javad Ashjaee was a brilliant engineer and an evangelist for getting cutting-edge GNSS technology into the hands of surveyors at reasonable prices. S...
It's also a way to identify an unauthorized print. I've never had to do that, but just in case I generally use a custom font for some elements, and ...
Great video! Long, but comprehensive enough that I think a beginner could follow it to effectively use the software. I've been using Star*Net in my...
The Leica GKNL4F is a 13' 3-section fiberglass rod that works well for most non-critical applications. Smaller and lighter than the GPCL2 invar rod, ...
I don't understand the advantage. Since Star*Net (and, I assume, other adjustment software as well) adjusts the topo shots to fit the adjusted contro...
Rothbucher doesn't exactly give those little tripods away -- Berntsen lists them at $385, and that's before you've added a 5/8-11 adapter. They do l...
The original plan was to bluebook it as a 3 cm ellipsoid height project. Station spacing averaged 7 - 10 km, with a few longer reaches. I started wi...
Well, maybe. I ran a large project using the 3 cm RTN guidelines with an R8-3 (GPS + GLN only) on a Trimble VRS, and a lot my sessions failed to meet...
As a certified old-timer, I did use a plane table a bit early in my career. I was mostly on the stick end of these stadia surveys, but got to observe...
