摘要
国产平台相较国外商用平台性能较低,在国产平台下实现矢量地图面临诸多问题。通过矢量数据压缩、复杂多边形的三角剖分、瓦片金字塔等方法对地图数据进行预处理,生成适合机载环境使用的数据,方便数据加载、检索和渲染。采用合理数据调度策略减少数据读取,优化要素渲染实现,可以在国产平台下平稳运行机载矢量地图。测试表明:采用合理的设计,在国产平台下可运行机载矢量地图。
Because of lower performance of domestic platform,a lot of problems arise in implementation of airborne vector map.By means of vector data compression,polygon triangulation,vector tiles and other data pretreatment,data applicable to airborne environment was gotten.The data is easy to download,search and render.Taking reasonable data scheduling mechanism and optimized items rendering,vector map can run on domestic platform.All these indicate that the domestic platform is able to run vector map when reasonable design is taken.
