我站在黄河口外长约70公里,宽达10公里的滨海地区进行潮流及水深测量。由于河口海岸地势平坦,水体宽阔,测区范围很大,进行观测时定位方法是一个急待解决的问题。过去我们出海勘测就因为定位的问题没有得到解决,离岸距离只有凭经验估计,成果粗糙,远不能满足需要,今年我站在工作中吸取了海道测量方面的经验,采用了海道测量部与我们在黄河口两侧沿岸设立的三角标系为主,作为海上观测定位
I stood in the Yellow River estuary about 70 km long, 10 km wide coastal areas for tidal current and water depth measurement. Due to the flat terrain of the estuary and the wide water body and the large measuring area, the positioning method for observation is an urgent problem to be solved. In the past we have not been able to solve the problem of locating the sea because of the localization problem. The offshore distance is only estimated by experience. The results are rough and can not meet the needs. This year, I took the experience of seaway measurement while standing in the work and adopted the seaway measurement department and us The triangular system set up along the coasts of both sides of the Yellow River Estuary is mainly used for observation and positioning at sea
