Research on digital 3D map visualization information system forhigh-precision GNSS positioning

为了保障GNSS定位的精度,提高数字三维地图可视化效果,文章提出了面向高精度GNSS定位的数字三维地图可视化信息系统。该研究设计采用Quantum II-BDS芯片作为GNNS芯片装置并使用Cesium进行三维地球可视化。通过更新地图显示状态、地图表面空间瓦片数据和矢量要素,实现地理信息的完整展示和高视觉效果。测试结果显示,该系统不仅能实现对地理信息的完整展示,也表现出了较高的视觉效果。

In order to ensure the accuracy of GNSS positioning and improve the visualization effect of digital 3D maps,this article proposes a digital 3D map visualization information system for high-precision GNSS positioning.The research design adopts Quantum II-BDS chip as GNNS chip device and uses Cesium for 3D Earth visualization.By updating the map display status,map surface tile data,and vector features,complete display of geographic information and high visual effects can be achieved.The test results show that the system not only achieves a complete display of geographic information,but also exhibits high visual effects.
