测绘服务由早期的模拟时代、数字化时代,发展到现在的信息化时代。信息化测绘涌现出一大批新技术,如GNSS导航定位技术、三维激光扫描技术、web GIS技术。新技术的出现,为服务国民经济发展提供了更全面的测绘地理信息技术支持,取得了重大的经济效益。本文从测绘地理信息服务总值与第三产业(服务业)发展水平角度,分析测绘技术经济在第三产业中的重要性及贡献情况。分析结果表明测绘经济效益领先于第三产业平均发展水平,测绘技术经济发展迅速,贡献比重逐年增加。
Surveying and mapping services from the early analog era, the digital era, the development of the information age now. A large number of new technologies have emerged in information surveying and mapping, such as GNSS navigation and positioning technology, 3D laser scanning technology and web GIS technology. The emergence of new technologies has provided more comprehensive geographic information technology support for the development of the national economy and achieved significant economic benefits. This article analyzes the importance and contribution of the technology of surveying and mapping in the tertiary industry from the perspective of surveying and mapping geographic information services and the tertiary industry (service industry) level of development. The results of the analysis show that the economic benefits of surveying and mapping are ahead of the average level of the tertiary industry, the economy of surveying and mapping technology has been developing rapidly, and the contribution proportion has been increasing year by year.
