Sorry I probably did a poor job of explaining the issue. It??s not drifting out of level while setup. The f1/f2 angles are drifting away from each o...
I came across this study measuring the accuracy of Trimble's RL measurement. ?ÿ ?ÿ ?ÿAs you can see, as soon as angle of incidence increases past...
Around 100m
You'd think. It's a 600 million dollar project over 4 years and there wasn't permanent pillars set throughout the site. I tried bringing it up and ge...
I'm having a tough time picturing this
Yea something along those lines would work well. No, this is in BC, Canada. Were in a ground based system scaled from UTM.
I think you misunderstood what I was getting at. RL isn't as accurate when your angle diverges from perpendicular regardless of how many times you sho...
That's one thing we were doing until they fully opened the highway and banned (safety) us from walking on the downhill slope side of the barriers (wit...
I can't seem to find any when I google them, any idea where I could look specifically?
These look fantastic. You've used these? Any idea at what distance the beam of RL would start causing issues? Either spilling over the sides of the fi...
The problem I see with using RL on this project is most of the time I'd be looking at a pretty oblique angle on the targets since it's a corridor. Obv...
Maybe these facts may clear things up a bit... I have levelling notes from May of 2021 coming from #800 (elev = 900.687) to #822 (elev = 961.865m) t...
A big thank you to everyone that responded. I finally got it sorted out. So the geoid was affecting conventional data, vertical deflection modelling ...
I am unfamiliar with vertical deflection modelling, how does one go about finding the correct .vdf file? When I run the conventional on its own for a...
?ÿ Ok I'm getting closer. So when I check the box for geoid modelling when ONLY processing my GPS data, I get good results. When I add in my conventi...
I think I should steer this conversation back or track a bit with some observations I've made. Lets forget horizontal for now and focus on elevations....
