Abstract: With the development of science and technology, survey and geographic information industry is booming. As an important result of this industry, stages of data acquisition, data processing, data application, and data service are included in the survey and geographic information software. With the construction of digital city, geographic information industries related to spatial information, such as new mapping, geographic information, and 3D modeling will be faced with new opportunities. Based on cutting-edge technology of survey and geographic information industry, including oblique photography, LiDAR, and 3D GIS, mature software both at home and abroad are analyzed, and the feasibility of localization of geographic information software in the construction of digital city is discussed.

Key words: oblique photography, real scene modeling, 3D point cloud, 3D GIS, airborne LiDAR, localization of software

摘要： 随着科学技术的发展，测绘地理信息产业获得了蓬勃发展。测绘地理信息软件作为测绘地理信息产业的一个重要成果输出，范围分布包括数据采集、数据加工、数据应用、数据服务各个阶段。随着数字孪生城市建设的推进，新型测绘、地理信息、三维建模等与空间信息相关的地理信息产业在数字孪生建设中找到了新的支点，获得了新的发展机遇。以测绘地理信息产业中倾斜摄影、激光雷达、三维GIS等前沿技术为依托，对国内外成熟软件进行深入分析，探讨数字孪生建设背景下测绘地理信息软件国产化的可行性。
