The development of science and technology promotes further development of construction engineering project construction,and traditional engineering survey technology is difficult to solve the problem of modern building survey,so it is necessary to actively carry out the analysis of precise engineering survey technology.Based on this condition,this paper analyzes the precise engineering survey testing methods,and studies the precise engineering survey from the perspective of practical application,and concludes that GPS measurement technology and UAV remote sensing technology have become important methods of modern precise engineering survey technology.Modern precise engineering survey technology is constantly improving with the development of the times.With the integration of survey work and science and technology,the quality of precise engineering survey will become better.
