测绘技术在延安治沟造地重大工程中的应用

Application of Surveying and Mapping Technology in the Major Project of Yan’an Channel Engineering

延安治沟造地土地整治重大工程是可持续发展战略下土地建设的新模式,测绘技术是重大工程建设顺利实施的有力保障。总结了传统野外地形测量、工程单体细部测量、低空无人机航摄、倾斜摄影等技术;介绍了传统测绘技术和新型测绘技术在工程建设各个阶段的作用、优缺点和使用现状。结果表明,传统技术与新型技术相辅相成,因地制宜地使用才能发挥最大效用。

The major land remediation project of Yan’an channel engineering is the new model of land construction under the strategy of sustainable development.Surveying and mapping technology is a powerful guarantee for the major land remediation project.In this paper,we summarized the traditional eld topographic surveying,surveying of details,the low-altitude UAV aerophotography and oblique photography at first.Then,we introduced the functions,advantages and disadvantages of traditional surveying and mapping technologies and new surveying and mapping technologies.The result shows that the traditional technologies and new technologies complement each other.The use of local conditions can make the best use of them.
