摘要
利用地理信息系统技术,以1987年和2000年的两期TM遥感影像为数据源,通过重点分析最佳组合波段的选择和水体信息特征提取的图像处理方法,得到这两个时期的成都市水域面积,进而实现水域变化的动态监测,并分析其对环境的影响,以便给水资源开发策略的制定提供科学的依据。
This paper took the year of 1987 and 2000 TM remote sensing images as the data source, with GIS, by attaching importance to analyze the selection of the optimum fusion bands and the methods of image processing wlfich the water information was extracted, could get Chengdu water areas at two periods, then dynamically monitored the changing of water areas, and analyzed its influence on environment, to offer scientific base for the establishment of the exploitation policy of water resource.
