基于矢量瓦片技术的国土资源数据快速更新服务研究

Study on Rapid Updating of Land and Resources Data Based on Vector Tile Technology

互联网技术的不断发展和完善使得网络电子地图得以迅速普及。但随着地图的移动化和应用的逐渐深入,栅格地图瓦片已不能完全满足人们的需求,矢量地图瓦片技术应运而生。本文从高性能矢量数据索引、分布式瓦片服务数据存储、分级索引调度的高效渲染、数据服务联动更新4个方面展示了基于矢量地图瓦片技术的数据快速更新服务研究成果,并以广东省国土资源数据为例,验证了本文技术方法的有效性和可行性。

The continuous development of Internet Technology has enabled the rapid spread of electronic maps.However,with the gradual deepening of map mobility and application,grid map tiles can′t fully meet people′s needs.Vector map tiles technology emerged as the times require.This paper presents the research on the rapid data updating service using of vector map tiles technology,including the high-performance vector data index,distributed storage of the tiles service data,high-efficiency rendering of hierarchical index scheduling and linkage updating of the data service etc.Taking land and resources data of Guangdong Province as an example,the validity and feasibility of the paper′s technical methods are verified.
