【摘要】：主要应用遥感图像处理软件ERDAS IMAGINE及地理信息系统软件Arc GIS,以不同时期(1990、2002、2006年)南宁市的遥感图像为数据源,利用遥感影像处理软件ERDAS对遥感图像进行图像配准、裁剪、分类以及提取边界等步骤,得到南宁市3个时期的城市建成区遥感影像分类图。把分类后的图像导入Arc GIS软件,进行矢量化处理;用Arc GIS软件的测量工具测量3个时期建成区的面积;把3个时期的矢量图划分成八个方向(东、东北、北、西北、西、西南、南和东南),并测量各个时期各个方向的建成区面积。统计南宁市1990、2002、2006年的建成区面积及其各个方向的建成区面积,计算和分析南宁市扩展速度和扩展方向;结合南宁市的其他方面信息,对未来南宁市扩展情况做简单的预测。
[Abstract]:The remote sensing image processing software ERDAS IMAGINE and the GIS software Arc GIS are mainly used as data sources for remote sensing images of Nanning City in different periods (1990 / 2002, 2006). The remote sensing image processing software ERDAS is used to register and cut remote sensing images.Classification and boundary extraction are used to obtain the classification map of the remote sensing image of three periods in Nanning city.The classified images are imported into the Arc GIS software for vectorization processing; the area of the three period areas is measured with the measuring tools of the Arc GIS software; and the vector maps of the three periods are divided into eight directions (east, northeast, north, northwest, west, southwest, east, northeast, north, northwest, west, southwest, east, northeast, north, northwest, west, southwest).The south and southeast of the area, and measured in all directions of each period of the area of the built-up area.According to the statistics of Nanning City in 1990 / 2002 and 2006, the area of the built area and the area of each direction are calculated and analyzed, and the expansion speed and direction of Nanning City are calculated and analyzed, and the future expansion of Nanning City is simply forecasted in the light of other aspects of Nanning City's information.
