[GRASS-user] r.mfilter.fp seg fault

[Thierry Schmitt]

Dear grass users and developers.

I have been investigating the r.mfilter.fp function with a relatively 
large raster file. My poor 6.3.0 version (on a x64bits - Poseidon 
(ubuntu) distribution) of this binary keeps sending me a deadly 
segmentation fault.
I would like to know if this is a known issue? If yes any suggestion on 
how to solve it?


thanks for your answers !!

Re: [GRASS-user] XTF reader neede - triton format for sonar

[Thierry Schmitt]

Hi Giovanni

There is nothing free to read XTF format that I know of.  The format is 
freely available on triton's website. The format has become a standard 
de facto. However it is still difficult to get a really standard xtf 
file in between the manufacturer of sonar processing software.

My advice would be

1) knowing the name of the application that acquired the sonar data.
2) have a quick look at MBsystem which is the only sonar processing 
software free as free beer!! It won't read xtf but you might find a way 
to find a common denominator.


I ll be glad to know how you proceed as I might be of better help if you 
are more specific (acquisition software, sonar)


Regards

Hi list,
I'm facing the need to process some sonar files in XTF (eXtensible
Triton Format), but I can't find anything as OS to do it.
Does anyone have experience with such a format?
