I overlaid the Open Street Maps data on top of the SAR imagery and there are some new town/villages missing from OSM. If I can't detect any yield variations at least I can digitize some urban area polygons for OSM.

OpenStreetMaps + Multi-temporal X-band SAR
I am making some progress in analyzing the rich AGRISAR 2006 Dataset ESA has so generously provided to me. The K-Means and SOM I implemented in QGIS are now coming in handy for classifying various crops and detecting in-field variations within the same crop - to validate in-field variations there is also harvester data similar to what I have worked with in the past, just noisier.
