How do you plan your control networks given a supplied accuracy spec?
When you are awarded a job with a given accuracy spec to reach at X confidence level for each main control point, what is your approach to plan your field work?
I’m a Starnet user and use the pre-analysis program which allows me to enter approximate coordinates, instrument specs and # of observations which I can use to either add observations, geometry or swap out instruments to hit spec and I find it works quite well.
If a simple closed traverse with the instrument we have on hand doesn’t meet spec I can start adding cross ties, extra common points, extra rounds of observations and if at a certain point the amount of extra observations becomes too great I can swap out instruments and rerun it. And of course after I process the actual observations I can verify whether it did or didn’t hit spec & reobserve if necessary but ideally I’m after a solution that has enough of a buffer that it doesn’t require an additional site visit.
Does anyone else have a different solution for planning their field visit?
