摘要
介绍了一种综合库容测量系统．在水库水下地形测量中，通过以ＧＰＳ定位技术为基础的ＧＰＳＤＦＳ三维数据自动采集系统，快速准确地采集高密度、高精度的水下地形数据，为建立新的库容曲线提供可靠的第一手资料．应用地理信息系统ＡＲＣ／ＩＮＦＯ软件，进行测量数据的综合处理、自动成图及库容计算，进一步提高了库容曲线的精度．
In this paper, a practical approach to the surveying of reservoir capacity is developed.On the basis of GPS orientation technique, with GPS DFS 3 D data collection system, underwater topographical data with high density and high precision could be collected automatically and rapidly. This data is the basic data for establishing a new capacity curve. With ARC/INFO software of GIS the data can be processed, maps drawn, and the capacity calculated automatically. Thus, the precision of the capacity curve is raised.
