摘　　要：针对大众GIS应用与服务对在线地图表达和性能要求越来越高,矢量瓦片成为地图引擎的首选,该文从地图矢量切片模型、编码规则、技术流程与跨平台应用研究等多角度,以主流的切片工具Mapbox Studio、GeoServer、ArcGIS Pro为例,对不同的地图矢量切片方案,从自定义矢量制图、切片环境、切片机制等方面进行了定性定量对比分析。结果表明:不同切片工具由于其切片环境和机制的不同,切片效率各有不同,适用于各自不同的应用场景,为在线网络地图引擎设计、开发和应用提供了技术参考。同时,该文提出通过自定义微服务网关的方式实现多套矢量瓦片服务对应多客户端调用需求,实现矢量瓦片跨平台应用。In view of the public geographic information system(GIS)application and service to online map expression and performance requirements are increasingly high,vector tiles become the first choice of map engine.Taking Mapbox Studio,GeoServer and ArcGIS Pro as examples,this paper made qualitative and quantitative comparative analysis of different map vector slicing schemes from the perspectives of map vector slicing model,coding rules,technical process and cross-platform application.The results showed that different slicing tools had different slicing efficiencies due to their different slicing environments and mechanisms,and were suitable for different application scenarios,providing a technical reference for the design,development and application of online network map engines.At the same time,this paper proposed to realize the multi-set vector tile service corresponding to the multi-client call demand by the way of custom micro-service gateway,realizing the cross-platform application of vector tile.
