摘要
以移动通讯数据传输技术、网络技术和时态数据库技术为基础,构建了导航地理信息的变化发现、分析甄别、采集、加工、处理、存储和发布服务一体化的增量式更新服务模式、技术、软件、质检和标准体系,论述了多源数据融合、时空模型及空间关系的动态实时维护、多尺度增量式导航电子地图综合处理、路径规划和质检方法等关键性技术,实现了导航电子地图近实时更新服务。
Based on mobile communications,data transmission technology,web and spatial-temporal database,an increment update service model is proposed by integrated data discover,data analysis,process,storage and publishing.Some key technologies-multisource data fusing,spatial-temporal model and real-time maintenance of spatial relationship,multi-scale map incremental update,route planning,quality inspection et.al,were discussed in this paper.The navigable digital map near real time updating services were realized.
