Abstract Land use change monitoring is a long-term task, its purpose is to find out about the land use change periodically or non-periodically and provide information for planning and administering. Application of TMdata to land use change monitoring was introduced in this paper. Post-classification comparison method was taken. The measure to reduce enlarged change range is to improve the precision of classification and calibration of multi-temporal Landsat data. In this way, the classified result for mono-temporal TMd ata can compared with others for any another mono-temporal TMdata, then the land use change information can be obtained.
