移动地图中的矢量瓦片组织方法研究

Study on the Organization Method of Vector Tile in Mobile Map

针对矢量数据地图发布,提出移动地图中矢量瓦片的组织方法,阐述了矢量数据的组织与管理、LOD技术和瓦片的构建、矢量瓦片地图的索引和显示。根据矢量数据的特点,确定矢量瓦片构建和存储方式,采用文件分层分级进行存储。

On vector data map publishing,the organizationmethod of vector tile,organization and management of vector da-ta was presented. we also introduces LOD technology and tilespatial index on this basis. According to the characteristics ofthe vector data,we constructs the map tiles and stored the mapdata by its level and classification.
