摘要
土地利用动态监测的目的在于定期或不定期地了解土地利用的动态变化趋势 ,为土地资源的规划和治理提供依据。本文介绍TM数据在土地利用动态监测中的应用方法 ,阐述了减少夸大变化程度的根本措施在于提高每次单独分类的精度及不同时相遥感数据的空间配准精度。通过对多时相TM数据单独分类结果的对比 。
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 TM data 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 TM data can compared with others for any another mono_temporal TM data, then the land use change information can be obtained.
