XS elevations not extracted

Question

After running "XS Cutlines Attributes -> Elevations", there is no XS Surface Table, and the cross section profiles are all blank when I export to HEC-RAS.  It seems like the DEM isn't being sampled, but I'm not getting any error messages.  Any insights would be greatly appreciated.

Answer 1

HI !

Did you check the DTM used for the interpolation (Option / DTM / Rasters selection) ?

Did you check the CRS of the DTM and the project / XS ?

Another way is to do it with HEC-Ras ...

Good luck
