Abstract：The problem as to how to form binary or multi mask image by ERDAS’s Visualization Modeler according to the condition with mult-interference information has been seldom dealt with in previous papers; nevertheless, this problem is really the key to deleting the interference information and extracting the useful information. In this paper, the authors discussed the method for forming binary or multi mask image by ERDAS’s Visualization Modeler, extracted and analyzed the iron-stained and hydroxyl anomaly alteration information based on the multi mask image and principal component analysis technology. The results show that the interference information or the false information can be deleted and the useful information can be extracted from the remote sensing image by masking based on the multi mask image, and that the high quality basic data can be provided for the extraction of the alteration information from the remote sensing image.
