it is saying that it can not allocate enough memory for the task .... > A local problem, or a general issue? looking at the WIND file, cols: 1777198 rows: 4927865 that is a very large raster you are trying to create... try: g.region res=10 -ap which should fix it. then a more reasonable: rows: 2460 cols: 3330 alternatively you could set v.to.rast rows= to a lower number, which would reduce the memory needs. but then you run out of disk space (unless you do have 8TB). also, looking at the data it might be better to make 2 raster maps, one for the NW block and one for the SE block. Completely empty data rows are quite efficient to deal with but big chunks of empty columns are not.
