| 摘 要： | 为了实现交互性强的实时按需在线制图,该文提出了一个基于矢量瓦片的矢量数据组织模型。依据矢量瓦片格式规范组织已有的矢量数据并生成配置文件,然后按照配置文件生成矢量瓦片并存储,为在线制图提供数据服务。实验表明,运用该模型可以实现实时按需在线制图,且渲染速度较快,渲染效果良好。

| Abstract: | To realize the on-demand and on-the-fly interactive online mapping,an organization model for vector data based on vector tiles was proposed.On the beginning,the raw vector data were organized on the basis of vector tile format specification and then the configuration files,lastly vector tiles were generated and stored according to the configuration files,and data service was provided to online mapping.Experimental results indicated that using the proposed model could make a real-time on-demand online mapping with high render speed and render effect. |
