Combine Terrains

[lue]

Hello everyone!

I hope I’m allowed to post this question here, if not, I’m sorry 😉

I’m having trouble combining to tiff-files to a new terrain in the RAS-Mapper (HecRas 5.0.3). I have done several 2D simulations before and also combined terrains.
However, now I have exported the interpolated XS-surface (from my river profiles) as a tiff file, and then – like usual – tried to create a new terrain using the newly created tiff and the original DTM.
Projection & resolution are the same for both tiffs.

Now, when creating the new terrain, importing the tiffs works fine, but the final step

“Final Processing: Terrain_IST.hdf
Step 1 of 3: Creating Terrain_IST.vrt…”

just stops at around 1/5 and does not continue (I left it for like 14hrs, no result).
I have to say the original terrain model is very large (400’000 KB), but still, has anyone experienced the same? Is there a limit to the size of input DTM’s? (there shouldn’t, since only import the DTM without altering it works)
I can also upload the data somewhere, but as I said, it’s really large…

I’d be very thankful If someone has some useful tips about this, starting to be frustrated…

Thanks!
Ben

Hy,
check your folder name. Or name of your project, .tif file… I had the same problem, because my folder name contained letter “š”. When i change it to “s” it worked.
