Mr. Neteler,
I'm wondering if GRASS has 64-bit raster and vector capability. I was able
to find that GRASS runs on 64-bit machines, but not able to tell if GRASS
has 64-bit capabilities on its own. I'm trying to justify the installation
of GRASS on one of our SPARC machines to perform operations on massive
raster datasets. Thanks in advance for your help!
Regards,
Greg

That depends upon what you mean by "64-bit capabilities".
Most integer variables are of type "int", which will probably be 32
bits. E.g. raster maps will be limited to 32-bit row/column indices,
integer cell values will be limited to 32 bits, etc.
The main advantages of a 64-bit architecture would be to allow the use
of files larger than 2Gb and/or the use of more memory than would be
available on a 32-bit system.
