【摘要】:为了满足对任意几何区域进行覆盖特性分析的需要,在传统网格点覆盖法对矩形区域进行覆盖特性分析的基础上,对网格点构建、卫星过境覆盖分析等环节进行改进,使其适合对任意几何区域进行覆盖特性分析的需要,最后以中国行政区域为例进行实验并通过过境特性表、过境重绘图和覆盖重数图等进行覆盖特性的可视化。结果表明了对地覆盖法在任意几何区域上能够准确地计算出其每次过境的覆盖区域及总覆盖区域,同时在实验分析中通过多种可视化方法展示目标区域的覆盖特性,使其更加直观。
[Abstract]:In order to meet the need of analyzing the coverage characteristics of arbitrary geometric regions, based on the analysis of the coverage characteristics of rectangular regions by the traditional grid point coverage method, the construction of grid points and the analysis of satellite transit coverage are improved. It is suitable for the analysis of the coverage characteristics of any geometric region. Finally, taking the administrative region of China as an example, the overlay characteristics are visualized through the transit characteristic table, the transit redrawing and the overlay multiplicity chart. The results show that the ground cover method can accurately calculate the coverage area and the total coverage area of each transit in any geometric region. At the same time, the coverage characteristics of the target area are displayed by various visual methods in the experimental analysis. Make it more intuitive.
