Abstract In this paper, the authors used multi-temporal CCD data from the CBERS—02B satellite and adopted the human-computer interaction to extract water information from the Tangjiashan barrier lake. Statistic analysis was employed to detect the change of the lake area so as to understand its variation and trend. The result can provide some quantitative basis for the study of geological hazards situation and hazards prevention.
