Prism Constants

Post by jimbowman » Thu Sep 18, 2014 9:14 am

Can anyone suggest or is there an easy way to edit a Field Genius traverse file to correct each distance to account for a wrong prism constant being set on the Total Station. Using a Sokkia Set 5 with Leica Prisms. Leica Prisms state that the prism constant is 0 but from further reading I think it is +34.4mm unless using a Leica instrument in which case it is 0mm.

Not sure if you use STAR*NET, but if you are you can add a prism offset records that can be applied to your measurements. You could then adjust and output the corrected coordinates.
