Problems!! (Digital terrain)

Postby raquel.anton.revuelta@gmail.com » Thu May 19, 2011 16:49

Hi everybody,

I started using MOHID a few days ago and I have got some problems with this software.

I want to calculate a Digital Terrain.

I have had problems with it, because i can't obtain a result. First, I changed the comas by points and I changed also the language of the computer (English). Then, I check the coordinate system, I tried with UTM and it didn't work, so I tried with Geographical coordinates and it didn't work too.

When MOHID start to run the Digital Terrain he stop in: Please Wait... and it never finish and it never show any error.

Could anyone help me with this?

Thanks a lot

Hi Raquel,

How big is your grid and how many xyz points do you have in your data?
Sometimes, with big files and big grids can take some time to run the digital terrain creator program...
If you send me the files I can have a look on what's going wrong.

Best regards,
Luis

Hello everybody!
I´ve tried converting a raster into a xyz file, but I guess I´m doing something wrong cause the size of the last file is so big, I cant open it in mohid studio and neither in mohid gis. The raster´s size is around 13Mb and the xyz file´s almost 1Gb. The raster cells are 5x5m. Can someone tell me please if this seem normal?
Thanks!!

Hello Ane,

the 1GB file will have trouble.
The raster is 5x5m but how many cells?
