基于Lea?et在线地图开源类库,设计了一种基于HTML5标准中Canvas标签的矢量瓦片显示方法。前端通过Ajax异步请求访问后台Web服务,后台服务对数据库中的空间数据进行空间和属性查询,并以GeoJSON的格式返回到前端进行绘制,从而实现移动端在线地图中矢量数据的高效显示。
Abstract：In this paper, based on Leaflet online map open source class library, we designed a display method for vector tile based on Canvas tag in HTML5. Ajax request was sent asynchronously to backend server in order to avoid blocking the main thread of the fore-end and therefore to ensure fluent user experience. Vector data in GeoJSON format were organized by a SOAP Web service after querying the Oracle database by spatial and attribute conditions.
