| 摘 要： | 以无锡市作为研究区域,采用2000年Landsat ETM+影像数据,通过对居民地的遥感机理分析,利用植被指数、水体指数、城镇指数相结合的方法提取居民地信息。分析遥感影像的谱间结构特征,通过试验,建立二值逻辑运算式,得到居民地遥感信息提取结果。并用该方法在不同时相不同地区的Landsat TM/ETM+影像上进行了进一步的验证。研究结果表明:该方法可以将居民地信息提取出来,并且效果较好。

| Abstract: | In this paper,taking Wuxi city as a case study area,selected Landsat ETM + image in 2000 as the data source.Based on the remote sensing mechanism analysis of the residential areas,vegetation index,water index,and the urban index are combined to extract the remote sensing information for residents.It can get the result of residential areas.Further study is carried on the Landsat TM/ETM + images of different time and different regions to verify the method.The results indicate that this model is effective with the high accuracy of the extraction. |
