摘要
介绍了高分辨率遥感图像用于城市土地利用信息提取的主要过程,应用ENVI软件作为试验研究平台对试验区进行了遥感图像分类处理。试验表明,遥感技术是进行城市土地利用信息提取的有效手段之一,针对遥感图像中出现的水体和建筑混杂的现象,提出了应用监督分类与矢量操作相结合的处理方法,可得到较好的分类结果。
This paper Introduced the main process of information extraction based on high resolution remote sensing image in the city land utilization. ENVI software was used as an experimental study platform which classified remote sensing image of the pilot area image. This experiment indicated that remote sensing technology is one of effective techniques of city land utilization information extraction and for the promiscuous phenomenon of the water body and the building in remote sensing image, better clacification resultt can be achieved through the combination of surveillance classification and vector operation.
