Abstract： In recent years， global positioning system （GPS） has been applied in many fields in China， especially in the field of surveying and mapping engineering. GPS technology can improve surveying speed， facilitate operation， and have good economy. Based on the example of 1∶500 topographic mapping in Dafang County， this paper analyzes the application characteristics of GPS technology， clarifies the key points of digital topographic mapping， and delves into the specific application of UAV aerial photography technology for reference by industry insiders.

Keywords： GPS technology; surveying and mapping engineering; application; digital topographic mapping; UAV aerial photography
