摘要
闹德海水库库区森林遮视严重，很难进行常规的三角测量，而采用ＧＰＳ定位技术，仅用很短时间就完成了库区横断面端点联网定位任务。作业过程中各项指标均优于规范规定的精度要求。实践证明，ＧＰＳ定位技术可以满足水库断面测量、地形测量、精度工程测量的要求。
The most area is hid from view by forest around the Naodehai Reservoir. It is difficult to triangulate. But using the GPS fixed position technology, the networking and fixing of cross section's end points can be achieved at a short time and the survey precision is higher than the prescriptive value in the specifications. The practice proves that the GPS fixing technology can meet the demands for cross section measurement, topographic and precise engineering surveying in reservoir area.
