针对地理线要素的分形特点,基于分形几何理论和小波分析理论,将小波分解算法和数值统计算法结合起来,得到等高线小波分解后各层细节分量具有对数线性的关系,从而通过计算原等高线对应的细节分量得到高分辨率下的插值数据。最后通过实验论证了该方法的可行性和有效性。 更多还原

【Abstract】 This paper presents a new interpolation which based on fractal theory and wavelet analyses, combining wavelet analyses algorithm and numerical statistic, and gets higher-resolution data by the way of calculating the details corresponding to the original contour line through a logarithm linearity of the each-level details of the wavelet-analyses of the line. Simulations study shows its feasibility and validity. 更多还原
