"If all you have is a total station then lots of shots with good description or code on each shot. But I would recommend using a laser scanner and scanning targets or paddle targets on Survey Control network."

Hi Mohammad. Afraid there is no way to bring the two data sets together.

The Garmin Handy is a pretty useful piece of kit, when used as intended, but even with WAAS enabled and differential corrections being applied, can only give +/-10ft accuracy at best.

Afraid will need to revisit the BMs already established with survey grade GPS.
