摘要
利用美国陆地卫星的TM图像资料 ,对山东省桓台县和垦利县TM图像资料进行计算机几何校正和不同的增强处理 ,以分类和非监督分类两种方法提取耕地信息。桓台县两种方法都取得较好的结果 ;垦利县由于地处滨海盐渍土地区 ,光谱差异性小 。
The TM image materials of Huantai County and Kenli County were emendated geometrically and enhanced differently, and the farm land information was derived by supervised classification and unsupervised classification. The result by using the two methods of Huantai County are both satisfactory. The two methods were also applied to Kenli County, but the result of unsupervised classification is better than that of supervised classification.
