| 摘 要： | 针对当前矢量数据组织方法在显示效率和效果方面存在的不足,提出了一种基于矢量瓦片的矢量数据组织方法。通过建立矢量瓦片的逻辑模型和物理模型,实现了基于瓦片的矢量数据表达;结合金字塔思想,实现了基于LOD的矢量瓦片调度。应用Open Street Map路网数据进行了相关实验,结果表明,该方法在保证矢量数据精度、便于制图和交互操作特性的同时,提高了数据调度效率,是行之有效的。

| Abstract: | For the Deficiency of the current method of displaying vector data organization efficiency , proposed a way to organize vector data based on vector tile .Logic Model and Physical Model was established for tile -based expression of vector data; implement the dispatcher of vector tile based on Level -of-Detail with the thought of tile -pyramid.An experiment is performed with route data from OpenStreetMap .The results showed that , it is effective to improve the efficiency of data scheduling on the basis of keep the preci -sion of vector data and the characteristics of convenient for drawing and interactive operation . |
