INVENTORY OF FOREST AND RANGELAND AND DETECTION OF FOREST STRESS typeⅠ-7 Progress Report, 1 Jan. -28 Feb. 1974

摘要

In a controlled experiment on EPTS color composites of forest and rangeland scenes in Colorado, photo interpreters could only separate forest from no forest. This is the simplest level of classification known as Regional in an ecological classification system called "ECOCLASS." At the Series level only 60-67 percent of the five major forest types could be correctly identified and is not acceptable. Four grassland classificat could be identified within a range of 50 to 100 percent at the Pries level of ECOCLASS. Again these levels of accuracy are not considered suitable for broad rangeland manning.
