Hello, my name is Miguel Silva and I am new to this group. I need help because I am comparing interpolation methods for precipitation, I am working with all the methods that GRASS has available but the v.vol.rst module is the only one that I can not really use, it generates the interpolation but when I export the raster it only weighs 1kb, and does not have any information.
When I’m doing the interpolation I do not load the raster to perform the cross validation, that’s why I can not do the interpolation well? … I’m not very good at working with commands, so the manual of the module vf.vol.rst, I can not understand it well.
when the method asks me for the name of the layer for cross validation, should I load a raster or vector with values x, y, and z that will be used to perform the validation? ..
If you could help me, I would be very grateful and excuse my English, it’s not very good ..
