【摘要】 利用遥感信息融合技术 ,对不同时相的TM和SPOT多源遥感数据进行融合 ,提出了一套基于变异特征的土地利用动态变化信息的监测方法———变异特征监测法。并以城镇居民点的动态变化监测为例进行了验证 ,结果表明 :与其它方法比较 ,利用该方法进行监测可以获得更高的位置精度和面积精度 ,具有很好的时效性和可继承性 ,且不受传感器类型影响 ,宜于推广应用。更多还原

【Abstract】 Using the fusion technology of remote sensing data, multi temporal TM and SPOT data is merged, and the feature change monitoring Method is presented to monitor land use change. By testing a case of monitoring dynamic change of urban residential area, it is showed that this method leads to better position and area accuracy compared with other methods, has a fine timely efficiency and inheritance, and rises superior to the types of sensors. And the method is easy to be popularized and applied.更多还原
