随着城市化建设进程的不断深入，建筑工程的数量和规模都在不断扩大，如何保证建筑工程的质量，成为人们关注的重点问题，建筑工程的测绘技术成为了保证建筑工程质量的重要支撑。科学技术极大的推动了建筑工程测绘事业的发展，将GPS 技术应用于工程测绘具有巨大优势，本文通过对GPS 在建筑工程测绘中的特点及应用进行阐述，彰显了GPS 应用于建筑工程测绘的巨大优势。 With the deepening of the process of urbanization, the number and size of construction projects are constantly expanding. How to ensure the quality of construction projects has become a key issue for people’s attention. Surveying and mapping technology for construction projects has become an important support for ensuring the quality of construction projects. Science and technology have greatly promoted the development of construction engineering surveying and mapping. The application of GPS technology to engineering surveying and mapping has great advantages. This paper elaborates the characteristics and applications of GPS in construction surveying and mapping, and demonstrates the application of GPS in surveying and mapping construction Great advantage.
