摘要
国内Cesium三维地图引擎研究方兴未艾,但在地质公园领域的应用却寥寥无几。基于Cesium技术进行开发研究,建立了三维地质公园导览系统。以3D Tiles格式的倾斜数据为基础,融合了地质公园二维专题数据;通过调用Cesium平台的相关接口,实现了地质公园的二三维可视化展示、空间量测和空间查询等功能。系统支持加载海量倾斜数据,兼容性强、浏览速度快,为在线浏览三维地质公园提供了可行的技术方法。
The research on Cesium 3D map engine is a hot topic in China, but there are only few applications in the field of geoparks. We used Cesium technology to establish a 3D geopark guide system. We fused the 2D geopark thematic data based on the oblique data in 3D Tiles format. Then we implemented the functions including 2D and 3D visualization display, spatial measurement and spatial query of geoparks by calling the relevant Cesium platform interfaces. The system can support loading massive oblique data with strong compatibility and fast browsing speed, which provides a feasible technical method for online 3D geopark browsing.
