对比了当前常用的地形图更新技术，分析了遥感影像变化检测技术的特点，选定变化区域，采用遥感影像变化检测技术进行了试验，并对试验结果进行了分析和验证。通过试验结论可知，采用遥感影像变化监测技术进行变化检测，并根据变化检测结果确定更新方法，再进行地形图更新的方法是可行的，且与常规的人工比对全面更新的方法相比较更具优势，可以避免人工比对的遗漏，保证数据更新的完整性和准确性，节省了时间，提高了效率，实现了地形图的动态更新。

Comparing the latest update technology which is current commonly used,we analyze the characteristics of re-mote sensing image change detection technology.We choose a changing area,then analyze and verify the result by using, and we get into conclusion that the method using the remote sensing image change detection technology,confirming renewed way according to the result of changing detection.Finally we go through the updating of topographic map and workable.It has make it more advantage than manual detection.And many omissions can be avoided.It keeps completeness and accuracy of updating,saves the time,improves the efficiency,and lets the topographic map can be dynamic updated.
