Method of line feature fractal data processing in subsidence area boundary

摘要：

In view of ecology evolution problems in mining subsidence area,the data fractal condition adjustment after subsidence area geographical map generalization was studied based on fractal theory In the paper.In the study of subsidence area geographical map multiple scale transform,the length and area condition equations were formed for subsidence area polygon end point coordinates after generalization,the method of solving as a whole was provide.This paper studied fractal adjustment based on data of subsidence area,obtained that the fractal dimension calculate method could be carried out about arc length and polygon area in comprehensive geographical map,it is possible for data of before and after comprehensive to fulfill the quality demands through fractal dimension condition adjustment solving,the fractal model calculation results in large scale comprehensive use well in practical example,the arc length and fractal area near to its original area when fractal dimension,scaling factor and other factors convergence stable;the difference between arc length,polygon area and its original area is smaller according adjustment coordinates calculation directly.
