摘要现如今城市发展速度之快是我们不可想象的。一方面,随着中国经济的快速增长,城市提供了更多的就业岗位,大批的农村人口涌进城市,城市住房问题变得棘手,于是开发商大规模的建造住宅以及小区旁边的配套设施,有必要对城市建筑物进行分类;另一方面,中国许多城市现在在迈向国际化大都市,所以也就意着城市的转型,城市转型就关系到城市建筑的更新换代,同时还有很多老旧建筑的拆除,城市新城区的建设,城市扩建等等。为了更好城市发展和规划,我们必须有城市建筑物分类这一个环节,只有把城市的建筑很好的分类,才能更好地把握城市发展的动态趋势,也是为了给我们自己创造一个美好而方便的城市生活。本文我就利用软件ENVI对高分辨率遥感影像的城市建筑物进行分类,并且大致比较几种分类方法。39162 毕业论文关键词:分类,ENVI,高分辨率
Abstract Nowadays urban development speed is beyond our imagination. On the one hand, with China's rapid economic growth, the city has more opportunities of employment, a large number of rural population flow into cities and urban housing is very nervous, so the developer launch large-scale conduction and build many community facilities, it is necessary to classify city buildings; on the other hand, many Chinese cities are now ready to develop into international metropolis. The transformation of the city leading to the upgrading of urban architecture, at the same time there are a lot of demolition of old building,construction of new city and the city expansion, and so on . In order for better urban development and planning, we must have a classification of city building,so that we can better grasp the dynamic trend of urban development, but also to create a good and convenient city life for us. In this article, I'll use software ENVI classifying high resolution remote sensing image of city buildings, and roughly compare several classification methods.
Key words:classification, ENVI, high resolution
