Thanks for all the suggestions. Especial the „Aven colored by error“ is a superb starting point. We do not always practice paperless caving but Disto X1/X2 devices are used for everything. So we get a SD from Calibrating - although to my understanding this value is something different then

I second Ollies advice. I'm a Therion user (not Survex), although I use survex loop closure. That gives some additional statistics in the Therion log file, but not the loop error standard deviations. I wonder if Therion (or Cavern) could incorporate these in the log file, or if Aven could be

... 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

To expand a little in this, you could also use the standard „grade“ to tell theriob which centerline data has which quality. We use this to mark the centerlines we have surveyed with distox and traditional way and therion uses this to put more of the errors towards the more bad survey. See

Our current project is nearing 2000 Stations in a labyrinth and things start to get cumbersome. We have more than 100 Loops detected by therion. I wonder what people use to find errors. For example im I have too loops L1 and L2 and L1 is “good” (0.1% error) while L2 is “bad” (4% error) i can
