摘要
为分析现代测绘技术在水库地形图测量方面应用的可行性与适用性,以位于道真县旧城镇关坝村的关坝水库为例,对包括测绘任务确定、像控点布设、外业低空摄影、水下地形测量、内业地形图绘制等在内的水库地形图测绘过程展开探讨。结果表明,现代测绘技术的联合应用能较好解决传统测绘过程受水库地形约束,测绘结果无法满足水库安全生产及运营管理需求等问题,并为水库地形图测绘结果质量及效率的提升提供了保证。
The feasibility and applicability of the application of modern surveying and mapping technology in reservoir topographic map survey are analyzed.Taking Guanba Reservoir,located in Jiuzhen Town of Guanba Village in Daozhen County as an example,the process of reservoir topographic mapping,including surveying and mapping task determination,image control point arrangement,field low-altitude photography,underwater topographic survey and internal topographic map drawing,is discussed.The results show that the combined application of modern surveying and mapping technology can better solve the problems that the traditional surveying and mapping process is constrained by reservoir topography,and the mapping results can not meet the needs of reservoir safety production and operation management.etc.It can guarantee the quality and efficiency of reservoir topographic map surveying and mapping.
