trimble survey controller static session

In my area, the grid to ground difference is small like Matthew, about 0.01 per every 100', but it does add up.

For me, I keep everything on state plane grid out in the field, whether using GPS or total station. I have not used a total station on a boundary survey in 2.5 years.Īs said, everyone has slightly different methods. Shawn really likes LDP's, which add another layer to the it depends answer. He could go to work robotically and not have to think much. I had a full time employee for a while and during this time I scaled everything to ground so I didn't have to worry with him making any changes to the software we were using. But, I usually scale the deed down to State Plane in cad and import that into jfield. If I need to set a corner it's easy enough to take the ground distance from the deed and enter that into the cogo functions in j field. I don't have to remember where I scaled it from when I survey next to something I have already surveyed. If it's a new project its state plane and it never changes. I will do the occasional localization and use those coordinates sometimes too. A year or or so ago I decided to keep all of my coordinates on state plane and never convert to ground based coordinates. It's a question every surveyor has asked himself. When I am back at the office I decide whether I want to adjust the conventional data to grid or if I want to adjust the gps to ground (this is only used as a check on our work). I then proceed to setup on my control points and continue through the job with conventional (total station equipment) and closing out my traverse with GPS if it is open ended. I usually set up a GPS base and set control/locate street monuments using rapid static with the Triumph LS and Triumph-1 Base. I have taken GPS courses in school but they mainly focus on large GPS static projects which does not apply to me directly.

I'm curious about the typical workflow that you would use for starting a new job from scratch, using both gps and conventional equipment for a boundary survey.ĭo you typically keep jobs on a grid or do you typically convert them to ground? I find myself going back and forth for different jobs but I think it would be better to have a consistent workflow so that I can become more efficient.Īs a new surveyor, I have not been able to find articles or books describing proper field methods for smaller boundary jobs.
