摘　　要：由于水利划界项目的勘测线长、分布范围广、周围环境复杂,采用传统方式获取数据工作量大,耗时费力。和传统方式相比,采用连续运行卫星定位服务系统(CORS)及数字摄影测量技术,可以快速获取所需的地理信息数据。本文在分析数字摄影测量原理的基础上,以苏州市某河道影像采集为例,介绍CORS和数字影像技术在水利划界中的应用。研究结果表明:新技术有更高的工作效率,数据精度具有独立性,且具有较好的工程实用价值。Since water conservancy delimitation project is characterized by long survey line,wide distribution scope and complex surrounding environment. Data acquisition through a traditional mode has disadvantages of high workload and serious time and labor waste. Compared with traditional modes,required geographic information data can be obtained quickly by using continuous satellite positioning service system（ CORS） and digital photogrammetry technology. Image collection of one river channel in Suzhou is adopted as an example for introducing the application of CORS and digital image technology in water conservancy demarcation on the basis of analyzing the principle of digital photogrammetry. The results show that the new technology has higher working efficiency,data precision is independent,and it has good engineering practical value.
