                         to extract information about trees from aerial images. Examples of 
                         output are the approximate number of trees, the diameter and area 
                         of a tree, and the total green area. For regions with sparse 
                         trees, a method based on segmentation and border extraction is 
                         described. It works reasonable well segregating trees from the 
                         other components (buildings, etc.) For dense tree areas, two 
                         feature baased methods, one using simple template-matching and the 
                         other one using a Backpropagation nerual-network classifier, are 
                         described. Both methods work reasonable well if a good sample of 
                         trees is provided.",
