Tomorrow’s going to be my second talk in German at MLU Halle. Here are the slides: russ2011mlu-slides.

And there’s also a video of the clustering here: In short, the video compares a spatial clustering on the precision agriculture data I have, using four variables (P, pH, Mg, K) and low spatial contiguity (left) as well as high spatial contiguity (right). The clustering is hierarchical agglomerative with an initial tessellation of the field into 250 clusters which are subsequently merged. The clustering has been implemented in R (generating .png files of each plot) with subsequent video encoding with ImageMagick (convert) and Mplayer (mencoder). Nice demo, I guess.
