Hi, Thank you for the video. I am doing interpolation of rain gauge stations having annual average rainfall. I want to use elevation as an external variable. Is there any way in QGIS to do that?

Great Hans van der Kwast! But, let's say I have the stations temperature file and another file with municipality/county centroids. Can I input the interpolation results into the centroids attribute table? So, in that way, I have an estimation of municipality/county temperature.

@HansvanderKwast 5 лет назад

Yes. You can use the point sampling tool plugin for that.

But I think it's better to have the average temperature per municipality. Then you need zonal statistics to calculate average temperature per polygon.
