Abstract Spectral reflectance characteristics of rock,soil and vegetation are analyzed based on field data,and a new method
for studying the geometric structure and spatial relationship of typical objects in the spectral feature space is put forward. In
addition, the distribution pattern and relation of typical objects in the spectral feature space within medium vegetation covered
mineral alteration areas are summarized. These conclusions serve as the scientific basis for mineral alteration information
extraction and are also useful to improving the method for extracting mineral alteration information.
