-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Stefan,
My post was in no way meant offending. I replied to Victor and Barry just because of the nice joke about "wizards". My experience at university is just that a lot of students use "wizards" without knowing what they are doing and Barrys post described exactly what I saw at university. I hope you will find (or already found) what you are looking for. With Kriging unfortunately I cannot help you because I just did not understand it ;) regards, Werner On 28/09/15 20:32, Stefan Keller wrote: > Werner, Barry > > I just wrote to have Kriging in QGIS with less external > *dependencies* like GRASS, SAGA (or R).
