Problem to read xyz file in GIS

[matthieu.caillaud@gmail.com]

Hello,

I've just installed MODHID 4.9.2 on WINDOWS 7 64 bits.
I can't read my .xyz file to create the bathymetric grid. i got the "invalid xyz file format" error .
I did read the Wiki page about the format of XYZ files (http://www.mohid.com/wiki/index.php?title=XYZ_Points) but it's still not working.
I also tried to download a xyz bathymetric file from ETOPO website and added the header and ending lines (<begin_xyz> and <end_yxz>) but GIS tell me it's an invalid format.

I checked that decimal separator is the point.
Does the blanks between the columns matter ? does the numbers of decimal matter ?

Could anyone help me please or send me a sample of an xyz file ??

Thank you

Matthieu

It seems that i have a problem with GIS. I tried to read an xyz file that i downloaded from MOHID website (fresh water cylinder test case) and it doesn't work.
Does anyone have some issues with GIS on windows 7 64 bits ?

Hello Mathieu
I have Mohid 4.9.2 installed on W7 64 bits and I had never had that problem.
But I suffered some unexplicable problems at the beginning. It was because I hadn't followed the correct installation sequence.

Have you installed Net framework in the version required by Mohid? And Office web components? Check it, please.


Best regards
Ana

Dear all,

in MOHID GIS you need decimal separator be set to a "." (your case) and no digit grouping symbol (confirm).

Number of decimals don't play a role.
The three columns should be separated by blank spaces (no TABS).

Example:
<begin_xyz>
0.0 500.0 1.0
0.0 100.0 1.2
500.0 1000.0 2.3
...
<end_xyz>

Did you tried to read the file with MOHID Studio? It works well on Windows 7 / 64 bits. With MOHID Studio you don't have to care about the "." setting.

Best regards,
Frank

It's ok !!

My problem was the decimal separator in my regional settings ......
Now it works fine and i can run my first model with mohid!

Thank you for your help and your fast response time
