GPS or Total Station?
GPS or Total Station?
(OP)
Hello:
I am not a profesional land surveyor but I have been reading a lot about DGPS giving such a great accuracy in the 3 sets of coordinates (x,y,z), I wonder what do we need a total station for?.
Would it be enough to get my 3 readings out of the point that I am interested in, and process that information?.
Will the Trimble R3 give me accuracies in the order of 1:4000 for closed traverses?. What do I buy?.
Thanks
José

Consider that the British, in their inimitable way, were able to measure the height of Mount Everest to within 200 ft of the modern value using ONLY transits and measuring chains.

GPS continues to come down in price and increase in performance. Hemisphere GPS advertises an OEM GPS board that has 2.5 m (95%) standalone positioning error and cm accuracy in DGPS mode for less than about $5K. But, it won't measure angles. Now, maybe you don't need angles, so ultimately, it's up to you to decide.

I hooked up the gps to a quad and rode up and down a section of land i needed a topo for. 10,000 elevation shots in one day. It was great.
Its nice to have both systems in your arsenal.
