Have now tried to run v.rast.stats in Grass 7.0. It start and run 100% off one core in hours, until a file in ~/grassdata/location/PERMANENT/.tmp/ inflate to the disk is full, approximate 150GB :(
Have made topology check on the vector-data and imported it to grassdb. Will see if I can collect usefull data and ask on grass-user list. Stupid Ubuntu 14.04 to not messure invisible files in the normal file-manager, had gone faster to pinpoint the problem. /Cheers 2015-04-19 18:54 GMT+02:00 Micha Silver <mi...@arava.co.il>: > > > On 04/19/2015 12:34 PM, Johan Nilsson wrote: > > Zonal statistics work well to extract, numers of cells(counts) , sum of > the value (sum) and also average (mean) But I want the minimum AND > max-value and also standard error, if possible.
