Remote Sensing for Sustainable Forest Management - Chapter 6 ppt

... roughly, forest covertypes, forest ecosystems, and forest stands — that can be managed uniformly (Bailey et al., 1978). The expectation in forestry is that the smallest landscape units, forests stands, ... to accomplish the goals of forest management. It seems unlikely that there will be a one-to-one correspondence between spectral response patterns, forest covertypes, forest eco...
