Hi all,

Surveying was completed using Topcon dGPS but when I upload the job files into Topcon Tools it tells me that the 'OSGM02: geoid model is not in the list. Elevations calculations will work incorrectly if you do not load this geoid'.

I have searched for a solution of the OS website but have not found anything. I have also tried uninstalling Topcon Tools and reinstalling all the geoid models available on the disc but this particular one isn't an option on the CD.

Any advice or help would be great!

Thanks

Www.ngs.gov - they have good links to find all kinds of geoid models to download

Typically if Topcon Tools is asking for a specific geoid model it is looking for the same model used in the data collector. If this is the case you can simply copy the geoid model from your data collector to your PC - a directory of your choice. Then direct Tools to the model on the PC.  

It may be a bit late but I think that this is what you wanted
