Abstract
The principle and method of precise trigonometric leveling technique are indicated through the analysis and research of elevation control survey status of port and waterway engineering. Based on one marine traffic project,the accuracy of precise trigonometric leveling technique is analyzed and compared with that of the leveling method,the advantages of the former one being applied in port and waterway engineering are also discussed,which will provide a new solution for the development of mapping work in the field of port and waterway engineering.关键词
