Hi All, I got some results from a variogram analysis on two remote sensing images with pixel size of 8m and 30m each. I would like to know the physical meaning of the variogram range over a forest target. The range varies from 5 pixels (40m) to 10 pixels (80m) for the 8m pixel size image (CASI), and from 3 pixels (90m) to 15 pixels (450m) for the 30 m pixel size image (Hyperion) from visible to near-infrared bands. 1. What these distances represents at the ground level ? They are to high to be associated to the tree size. How can I interpret this ? 2. For the variogram I computed from a mineral target, the range increases continuously as a function of wavelengths, what's that mean ?
