摘要
针对传统三维WebGIS系统通常需要安装浏览器插件且存在前期开发效率低、系统后期可维护性差的问题,本文提出利用Cesium三维地球框架结合Vue前端框架开发三维WebGIS的思路。系统通过Vue组织代码进行组件式开发,以天地图在线影像服务和本地发布的地形服务为数据源,利用Cesium构建三维场景,将“祁连山—阿尔金山”专题地图集在此三维场景上叠加显示,同时提供测量、等高线填充和坡度坡向分析等功能。结果表明,系统具有开发周期短、后期可维护性高、操作方便、界面流畅的特点,并且能立体、直观、全方位角度展示专题地图。研究结果不仅能满足第二次青藏科考的需要,还能服务于祁连山国家公园建设和其他研究工作。
In view of the problems in the traditional 3D WebGIS system,for example,it needs to install browser plug-in and has low development efficiency in the early stage and poor maintainability in the later stage,the idea of developing 3D WebGIS with cesium 3D Earth framework and Vue front-end framework is proposed in this paper.Taking“TIANDITU”online image service and local terrain service as the data source,the system conducts component development through Vue and constructs 3d scene with Cesium.The thematic atlas of“Qilian-altun mountain”is superimposed on this 3d scene,and it also provides functions such as measurement,contour generation,and slope and aspect analysis.The result shows that the system has the characteristics of short development cycle,high maintainability,easy operation,and smooth interface,and can display the thematic map from a three-dimensional,intuitive,and all-round perspective.The results can not only meet the requirements of the second Qinghai-tibet scientific expedition,but also serve the construction of Qilian mountain national park and other research work.
