YANG Ze-yun1, YANG Gui-jun2(1. Heilongjiang Institute of Technology, Harbin 150050, China;2. Liaoning Technical University, Fuxin 123000, China)  
Based on ENVI software, the computer classified method of remote sensing image with ground elevation information is studied by analyzing the processing methods of calibration, noise elimination, band ratio analysis, characteristic change cancellation of feature spectrum etc. of remote sensing image with ground elevation information. Taking the ground elevation information will make image result after classification approach real ground circumstance, satisfy the applied requirement after classification.
