Abstract:

3D modeling is one of the core technologies in the digital earth, and it plays a significant role in the development of digital cities, digital earth, and digital economies. Currently, many countries have initiated various 3D modeling projects to support natural resource management, urban planning, emergency response, and sustainable development. At the same time, these projects have also promoted the development of 3D modeling technology. This article analyzes the research and application of 3D mapping across different countries, focusing on four aspects: “needs assessment” “tasks” “technologies” and “applications” based on the fundamental definitions and connotations of 3D mapping. By summarizing and analyzing typical 3D modeling engineering, products, technology, standards, and applications in these regions, the article explores insights into the construction of 3D realistic geospatial scene in China and provides references and insights for the development of realistic model projects domestically.

Key words: national-level 3D modeling, platform services, specification
