发布时间：2018-12-15 04:25
【摘要】：为解决LBS技术中组件式地理信息服务在车辆监控应用中研发成本和应用门槛较高的问题,基于第三方地图服务,研究分别从数据层、中间处理层与用户交互层出发,实现坐标系统转换、空间数据筛选与图形叠加等监控数据地图可视化关键技术,将数据层中不同源空间数据筛选转换成用户层中图形可视化交互信息。研究实现实时位置追踪与车辆行驶轨迹等基础功能,验证了监控数据地图可视化技术的可行性;并测试空间数据筛选技术的有效性,数据筛选率最高为30%。
[Abstract]:In order to solve the problem of high R & D cost and application threshold of component GIS in vehicle monitoring and control application in LBS technology, based on the third party map service, the paper starts from the data layer, the intermediate processing layer and the user interaction layer, respectively. The key technologies of monitoring data map visualization, such as coordinate system transformation, spatial data filtering and graph superposition, are realized, and different homologous spatial data filtering in data layer is transformed into graphical visual interactive information in user layer. The basic functions of real-time position tracking and vehicle track are studied to verify the feasibility of the visualization technology of monitoring data map, and the validity of spatial data screening technology is tested. The data screening rate is up to 30%.
