Can you show me a good site about topography? - topography software

In fact, I have a problem with my software. I have a Total Station - Leica TC805. The problem is the compatibility between Leica GeoOffice (TS soft) and soft TopoSys 5 (a program that is the compensation required). I am an engineer in the topography, but the TS (total station) is very high tech. We therefore need a better output TopoSys used under license.
Note: This question is adrressed engineers and specialists in my area. But newcomers can also try to solve my problem. Thank you.
