... forgot to mention, survex can display the errors visually, when generated 
from therion this way. When you marked the surveys accordingly you can see 
which loops are bad and which ones are good in the polylines. This greatly aids 
in finding problematic or faulty measurements.

For traditional surveys i also usually get good results with the morphing 
information of therion (big morphing at stations suggests faulty data when the 
sketch is accurate).
