[GRASS-dev] terracost and large files more generally

[Gerald Nelson]

While you (plural) are cranking on the next release, it's probably not the best time to ask but... 

- would it be possible to add the terracost functionality to r.cost (http://www.bowdoin.edu/~ltoma/research.html). My impression is that for a C programmer it would be fairly easy. 

- file size limitations issues. I'm bumping up against a 2 gb limit in r.out.arc. We're using grass6.3, compiled with large file support and we can't export files that would be larger than 2 gb. My postdoc (who knows java but not C) and I looked at the source code for r.out.arc and couldn't see any obvious reason why there would be a size limit.

Thanks,

Jerry
