| Abstract: | Based on the spectral characters of vegetation, this paper attempts to analyze the methods and actuality of vegetation information extraction, particularly discusses several typical methods, such as Vegetation Index, NDVI combined with bands, HIS, Hierarchical Classification Technical Extraction and Knowledge-based Vegetation Extraction methods, together with their principles, effects, functions and limited conditions. Finally, summary and prospect are described, in order to give guidance to practical work. |
