Abstract： Land resources are the most basic strategic resources，and conducting topographic surveys is one of the key measures to ensure efficient development of land resources. Unmanned aerial vehicle photogrammetry technology is anew type of measurement technology developed based onadvanced digital technologyand remote sensing technology，whichcanasist in theautomation transformationof terrain measurement work，improve terrain measurement accuracyand quality.In the new era of digital and intellgent development in terrain measurement， relevant departments need to studyand atach importance to unmanned aerialvehiclephotogrammetry technology，and improve the levelof terain measurement through unmanned aerial vehicle photogrammetry technology.This article analyzes the advantages of unmanned aerial vehicle photogrammetry technology in digital terrain measurement，and summarizes and elaborates on specific application strategies.

Keywords： drone; photogrammetry; digitization; topographic survey; application
