Multidimensional space angle method for alteration information abstraction from vegetation covered area has been presented in the light of spectral angle mapping in this paper. 摘要基于光譜角制圖法，提出運用多維空間角度方法來(lái)提取植被覆蓋較好區域的遙感圖像蝕變信息。
The work shows distinctive layers of vegetation covering the high mountain of Shie-Pa, as well as the expansive forest that silently nurtures the thriving organisms. 作品表現層次分明的植被覆蓋在雪霸的高山上，廣披的林木默默的滋養孕育出生生不息的生命物種。
