I have a vector dataset of mean annual precipitation polylines, and I would like to generate a raster from them. I'm not sure the best way to go about it. ArcGIS has the Polyline to Raster tool but from reading its help file I get the impression it's not really designed to do what I need it to do. Obviously some kind of interpolation is required. I am hoping that SAGA-GIS might have a useful module. Either that or I guess I could convert the lines to points and then krige them.
I would appreciate learning from others' experiences on this one.
