+# Description
+The Pavia Centre and University are two scenes acquired by the [ROSIS](http://www.opairs.aero/rosis_en.html) sensor during a flight campaign over Pavia, nothern Italy. The number of spectral bands is 102 for Pavia Centre and 103 for Pavia University. Pavia Centre is a 1096 $\times$ 1096 pixels image, and Pavia University is 610 $\times$ 610 pixels, but some of the samples in both images contain no information and have to be discarded before the analysis. The geometric resolution is 1.3 meters. Both image groundtruths differenciate 9 classes each. It can be seen the discarded samples in the figures as abroad black strips.
