摘要
在进行海洋重力和水深测量的时候,由于各种原因会造成部分测量数据带有较大的误差或出现错误。根据海洋重力测量时同时进行水深测量的作业方式,通过实际测量数据,利用海洋重力数据和水深数据的相关性,介绍了在数据后处理中海洋重力数据和水深数据的相互参照作用,以判断测量数据的正确与否,便于删除错误数据,提高测量数据的质量。
When taking Survey of the ocean gravity and the water depth, there will be lots of bigger error margin data and mistaken data in the survey because of various reasons. According to the operation mode of taking the water depth measuring and the ocean gravity survey at the same time, through the actual measure data, to make use of the correlation of the ocean gravity data and the water depth data, introducing how to handle data according to the functional mutation of the ocean gravity data and water depth data to judge whether the measure data are exactly or not ,then easily to delete the mistake data and raise the quantity of the measuring data.
