Fractal Data Processing Method of Boundary Line Feature of Subsidence Area

摘要

According to the problem of ecological evolution of mining subsidence area, this paper based on fractal theory to conduct fractal terrain simulation of subsidence area and research work of fractal conditional adjustment after topographic integrated. Studies show that: Fractal terrain simulation of subsidence area boundary through Fractal Interpolation Principle based on Affine Transformation and interpolation data by Fractal Brownian Motion Model, can better achieve 3D terrain visualization of subsidence area. In the research of topographic scale transformation of subsidence area, established the length and area of the condition equation of polygon coordinate data of subsidence area, and given the integral solution method. Example shows that this program ensures the quality of data of subsidence area, and improved comprehensive accuracy of data.
