Hey all, This is sort of a newbie question, but I'm hoping you all might have some guidance... This summer I've been tasked with setting up a total station (we'll be using an older Topcon GTS-230) for some mapping work. I've taken points using the prism, etc. but this was all after the TS was setup. Specifically, I need some advice or pointers on how to setup a total station grid. I've been able to find a whole bunch of information on leveling the total station, so I think I'll be OK there. However, most of the videos and manuals I've found online seem to skip the next step: setting up a grid. We have a known point that I'll be setting up the TS over. I'd like to shoot in UTM coords, so the grid "0" point will be the UTM coords of the known point (yes?). My question is, what is the next step? How do you tell the TS which way is North (and is that magnetic, grid north, etc.?)? I've read about backsight setup, but I don't think we have another known point in the area. Without this backsight, do all the points we've taken for that field day need to be altered through post-processing somehow? Also, as a corollary, we also have a Topcon FC-120 field collector unit. Are there any neat ways to use this in the field? Or in combination with the TS? Or will it just collect dust if we're only shooting in points w/ the TS? Thanks for the assistance!
