Hmm-m-m. I'll read the v.surf.idw manual page.
I don't see how v.surf.idw is helpful here. The current map has only category values and the label for each station. Interpolating station locations or labels makes no sense. The precipitation data for each station has not been entered in the sqlite3 attribute table. More to the need of this project would be extrapolation as the project area is east of this cluster of weather stations. What I need to show are the locations of the weather stations relative to the project area and the variability of precipitation among sites for any given day. I don't see how interpolation of any of these data is useful. If I'm wrong, please educate me.
