摘要
介绍了利用ＧＰＳ等先进技术测定库容数据处理中的几个关键问题。坐标解算中，参考椭球的大小及定位、坐标转换参数的选择和确定、投影变形、高程系统等不可避免影响到库容的精度。具体阐述了上述各项系统误差的影响规律及其消减模型，在生产中具有很好的实用价值。
This paper deals with several key problems about data processing in general surveying system of reservoir volume by GPS method. Coordinate calculation, scale and position of reference ellipsis, election and determination of coordinate transformation parameters, projection reformation and height system are main influences effects to accuracy of reservoir volume observed. This paper analyzed the rule of the above effects and proposed reduction model in detail. It will play an important role in actual practice.
