Surface and Raster (ortofoto) format / Some assistance needed
« il: Maggio 06, 2025, 07:03:58 pm »
Ciao,

Sto cercando di importare un file .asc (DEM) e sovrapporlo a un rilievo speleologico.

Tuttavia, evidentemente sto sbagliando qualcosa, perché continuo a ricevere il seguente errore:
"no usable coordinate transformation found"
in cSurveyPC.cSurvey.Calculate.cCalculate.pCalculateSegments(cTrigPointCalculateItem Origin, cSegmentGroupCollection Groups)
nel file D:\Personali\cSurvey\cSurveyPC\Calculate\cCalculate.vb:line 1635.

Esiste un tutorial, oppure qualcuno potrebbe spiegarmi come importare e utilizzare correttamente un modello DEM di superficie con un rilievo di grotta in cSurvey?

Grazie mille!

Hello,

I'm trying to import an .asc file (a DEM) and overlay it on a cave survey.

However, I'm clearly doing something wrong, because I keep getting the following error:
"no usable coordinate transformation found"
at cSurveyPC.cSurvey.Calculate.cCalculate.pCalculateSegments(cTrigPointCalculateItem Origin, cSegmentGroupCollection Groups)
in D:\Personali\cSurvey\cSurveyPC\Calculate\cCalculate.vb:line 1635.

Is there any tutorial available, or could someone please explain how to properly import and use a surface DEM with a cave survey in cSurvey?

Thank you!

Is a strange error...some years ago there was a bugged Therion version that raise this error in same case.
Are you using an updated Therion and the last cSurvey?
if yes could you send me (even on forum) a simple survey with one shot, a station with coordinate and the dem file your are using so I can try to reproduce the problem in my installation.
