摘要
以360°街景地图为空间载体,通过Leaflet库实现矢量地图服务的服务解析,再对解析数据进行三维坐标变换及格网划分分片加载,实现将矢量地图服务转换到360°街景地图空间,并解决加载效率问题;最后按照数据类型以相应的绘制方式在360°街景空间中进行表达。该融合表达方法的研究,解决了矢量地图服务与360°街景割裂表达的问题,为统一360°街景地图与传统二维地图的功能应用提供了参考。
In this paper,the 360°street view is used as the space carrier,the service analysis of vector mapping is realized by inheriting the Leaflet library,and then the 3D coordinate transformation and grid partition loading of the analytic data are carried out.The vector mapping is converted to the 360°street view space,and the loading efficiency is solved.Finally,the corresponding rendering method is expressed in the 360°Street View space based on the data type.Through the study of the fusion expression method,the problem of separating the vector map service and the 360°street view is solved,and the reference is provided for the 360°street view and the traditional two-dimensional map in map function.
