Cost Distance Analysis with large rasterfile

Discussion created by esnov1 on Feb 9, 2011
Hi there!

I'm struggling with the problem, that i need to calculate a Cost Distance from a quite large file (the target raster dataset is ~40mb, the cost raster dataset is ~210mb). Now the proccess is running, but after some hours still is remaining at 0%...
My computer has got an AMD Turion 64 with 1.80 GHz, 2GB RAM. Anybody has got an idea how long this is going to take, since I have to finish this project in the next 4-5 days.

Which options are there, to speed up the proccessing, besides increasing the cell size (which isn't really an option to me, as I need the resolution)?

Thank you really much, hopefully I get some help!
Sebastian
