Resection

I found that I might be able to create my own control points if I use the resection function of the total station. Basically what the instrument does is it takes multiple measurements  between two points from a central travers set up. Then what it does is it takes the standard deviation of all those points. From there if there was a measurement that has a particuarly high sigma you can throw it out. this technique will make throwing my own control points easier hopefully since I am already have a useful set of reference control points.  The problem I was having with setting up my own control points before was that I had nothing to go off of except assumed coordinates which have to eventually be rotated onto UTM coordinates in order to actually have  been able to do any of the stake out that we have so far.
