The spatial variation in two types of Synthetic Aperture Radar (SAR) images covering agricultural fields is analysed. C-band polarimetric SAR data from the Danish airborne SAR, EMISAR, have been compared to space based ERS-1 C-band SAR with respect to scale and effect of polarization. The general concepts of the semivariogram are presented, prior to applying the semivariogram to the data. It is found, that the spatial variation detected in the images from the two different platforms are comparable in spite of the very different spatial resolutions. It is also found that polarization has a pronounced effect on the results, and that the spatial dependence in data shows a strong anisotropy.
