基于分形的DEM精度评估

The Accuracy Evaluation of DEM Based on Fractal Analysis

分析讨论了DEM精度评估的主要研究内容、影响DEM精度的主要因素、基于等高线数据的DEM内插算法以及精度评估的模型和方法。提出了一种基于分形分析的DEM精度评估模型,为DEM精度的科学评估提供了一种新思路和新方法。

This paper analyses and discusses the main objects of accuracy evaluation, the main factors affecting the accuracy of DEM, the interpolation methods of DEM based on maps contour data, theories and methods for accuracy evaluation and the model of accuracy evaluation. And it proposes a new model based on fractal analysis and a new idea for quality accuracy evaluates of DEM.
