How to combine GNSS RTK survey data & Total Station data into one topo survey

We have been using RTK survey solutions and Total Station survey separately on topos but now wish to combine the two techniques into the same survey, to leverage the strengths of both these solutions.

I'm looking for advice or a start point for investigation on how to accomplish this.

Kind regards

Hi Ian,

you had quite a few reply's to this topic, as I recall you use Trimble R8 and ??? Total Station

if both Trimble you can use Integrated Survey:

Setup/Resection over GPS/GNSS min:2 points to work but take at least 3  and don't forget

do not work out of your resection area. Setup accuracy GPS/GNSS , Survey accuracy TS in itself.

On Accuracy:! always depends what your Survey is used for/ requirements of your Clients.!

If you have to different systems its more or less the same as Integrated you just setup your control with GPS/GNSS and do Survey with TS again stay within your resection area. Don't have your longest Backside 100m and Survey 200-300m from this setup you just implement errors (see above).

Just remember the scale factor and of course setup accuracy if required Hard level control stations/TS can work too again !...!

Yea, for the Data Collector, so this is how you make a round world flat or is it a flat world round.

 Either way sounds good to me.

I'd just like to thank you guys for taking time out to provide advice and guidance. You've provided some great information to invistigate and follow.

Thank you
