Kiaora GRASS!
I require a network tool which can calculate 'service areas'. I know
GRASS can currently do this but the specific problem I have is
that I
need to do it for a very large dataset (400,000 locations). I tried
this with ArcGIS tool (sorry!) but it failed to 'solve' due to an
overloaded memory. Would the GRASS tool 'v.net.iso' be able to
process
this without breaking?
I don't have a straight answer to the question, but generally GRASS
can handle fairly large datasets. It might depend more on the
resources of your machine.
The best way to find out would be to try. ;-)
..And please let us know :)
Yes ! :-)
As a follow-up: you might want to try grass7 as AFAIR some improvements
in the modules only exist in that version for the moment. MarkusM can
you confirm that ?
