@ Norman_Oklahoma Maybe I did misunderstand the YouTube video. Probably the same angle adjustment logic is good for any kind of closed traverse. I for...
@ john-hamilton We've been adjusting raw data (traverse point elevations - for a topo) in our data collector and coordinate data (traverse point N, E ...
@ I love my job Will look for it next time. Thanks.
@ Jon Payne If that was the process, I would expect that the difference in distance between GPS102-GPS101 is indicative of the error in the GPS observ...
@ Jon Payne To get these values, did you collect the GPS points and start with them in the collector based on just exactly what was collected via NRTK...
@ OleManRiver How do you PM someone on this website? I need this weekend to sort out all of this information presented to me.
@ Norm I appreciate your input, but this is our standard way of doing things. My coworker and I are trying to institute new methods of doing things. H...
@ OleManRiver I'm not sure about private messaging on this new website. Thanks for the info. I'm using this job as a model for similar jobs in the fut...
@ Norman_Oklahoma Comparing SP grid coordinates to ground measurements this may account for the greater part of your misclosure. GPS102-GPS101 Grid di...
The traverse was completed yesterday. The closing azimuth was 6" less than the record azimuth. The traverse length was 3338'. The error of closure was...
@ dwoolley Is the “always have a long backsight” an old wive’s tale? Not exactly. It matters if you are setting points or collecting coordinates. A 0....
@ RobertUSA Thanks for your help.
@ Norman_Oklahoma I don’t know if we could select a closer base. I could switch to a multi-base solution.
@ WA-ID Surveyor Unfortunately, we're going to have to live with those 2 unbalanced legs. Had to get around a 90° curve. Contrary to that, 2 and 5 are...
@ Jon Payne That's some fascinating stuff. Thanks for deciphering the data.
@ WA-ID Surveyor I assume you are traversing due to non-gps friendly work throughout the corridor? The office probably wants to traverse for that reas...
@ Jon Payne If you have the vector data and error ellipses for the GNSS points, why not incorporate that data into your adjustment. Great idea. Thanks...
@ OleManRiver What field software are you running with? Topcon MAGNET Field. Thanks for the advice concerning grid and ground. We got rained out today...
