| 摘 要： | 新型智慧城市地理信息底层建设,广泛应用BIM、VR、AR技术,以及数字航空摄影测量、高分辨率卫星遥感、无人机摄影测量系统等地面成果建立三维模型,但仍是感官成果,缺少计算思维。文章提出大数据环境下,应用地理信息成果建模所呈现的不仅是"看到",还需要具有计算思维,具有测绘语言,满足智能需求的"可计算"成果,乃至开发"计算思维",进而促进"计划科学发现的偶然性"。基于倾斜摄影实景三维技术和机载LIDAR技术构建地理信息公共服务平台的尝试,初步体现了"计算思维"理念。

| Abstract: | New smart city geographic information underlying construction has widely used BIM,VR,AR technology, digital aerial photogrammetry, high-resolution satellite remote sensing, and UAV photogrammetry systems from which the results are to establish a 3 d mode,but which is still a sensual result,and lack of computational thinking.This paper puts forward,in the big data environment,the results that the geographical information show s not only"see",but also need the computational thinking and surveying and mapping language to meet the intelligence required results which can be calculated,thus developing the computational thinking in order to promote"contingency of planned scientific discovery". The beneficial attempt of constructing geographic information public service platform is based on tilt photography 3d technology and airborne LIDAR technology which initially reflecteds the concept of"computational thinking". |
