| 摘 要： | 介绍一种基于Mapinfo Arcview Excel的线体分形方法.该方法用Mapinfo对线体栅格图像进行矢量化,用Avenue语言设计自动画网格程序,用Arcview中的Geoprocessing模块提取线体分形数据后用Excel对分形数据进行计算,得出线体的分维值.用该方法对直线进行网格分形分析,得到直线的分维值为0.9969,误差率为-0.31%.该方法可以自动生成拟合线性图,及其线性方程和相关系.不仅操作简单而且计算精高.

| Abstract: | The papers puts forward a method to investigate fractal of lines based on Mapinfo+Arcview+Excel.By quantifying grid image of lines using Mapinfo,designing the procedure of drawing grid automatically using Avenue language,combining with Geoprocessing module in Arcview to extract the fractal data of lines,and calculating fractal data using Excel.Analysis is carried out on the gird fractal linear with this method and the fractal dimension of linear was 0.9969 and the error rate was-0.31%.The result shows that ... |
