航空摄影测量在水利工程地形测绘中的应用与分析

APPLICATION AND ANALYSIS OF AIRBORNE PHOTOGRAMMETRIC IN WATER ENGINEERING TOPOGRAPHIC SURVEY

水利工程地形测绘资料是水利工程设计的基础,航空摄影测量又是获取工程地形测绘资料的先进方法。不同水利工程设计对工程地形测绘资料的精度要求是不同的,合理地选择航空摄影仪及航摄比例尺,是保证水利工程地形测绘精度的关键,也是水利工程地形测绘技术设计的重要技术措施。

Topographic survey and mapping data is the basis for the design of water conservancy projects, and aerial photogrammetry is the advanced method to obtain the data of engineering topographic survey. Accuracy requirements of every water conservancy projects design of engineering terrain survey and mapping data are different. Suitable choice of aerial camera and aerial photography scale is key to insurance of the accuracy of topographic mapping of water conservancy projects and important technical measures of the water conservancy project terrain mapping technology design.
