I need to make kriging analysis in QGIS (v1.7.4). I found out, that it should be a part of SDA4PP plugin, but I just couldn't find it in any repository (even third party). It looks, like it just disappeared from the web. Is it possible that I did something wrong?

Thanks

It's marked experimental. Allow experimental plugins in plugin installer options. Don't know if it works with latest versions of QGIS and all dependencies. – underdark Apr 8 '12 at 19:19
    
Thanks for answer. It works for making it available for install. But it was beyond my ability and time capacity to make all these dependencies working on Windows Vista. – ospa Apr 8 '12 at 20:33
    
At one time I did manage to get SDA4PP working (for kriging) with QGIS, but not in the current versions. The new Sextante plug-in has several useful-looking kriging modules but I can't get anywhere with this either, just at the minute. It looks as if it's going to be very good, hopefully before too long. – nhopton Apr 9 '12 at 8:14
    
Sextante plugin is very new and far from stable. It cannot be recommended yet but will hopefully be a very powerful tool soon. – underdark Apr 9 '12 at 10:39
    
Hi, is it necessary to do the kriging in QGIS? I am using SAGA GIS (opensource, much more tools) for raster analyses and processing and then load my rasters in QGIS for map finishing. – Juhele Apr 10 '12 at 5:55

The most robust way to conduct kriging in QGIS is via the SAGA processing tools. It comes with two kriging techniques: ordinary and universal.

The SDA4PP part of the question is best answered in: How to install SDA4PP plugin for Kriging in QGIS?
