摘要
走航式适航水深测量是目前港口工程测量提出的新课题,对其测量精度的评定和准确度的检验尤为重要。从两个方面论述了适航水深测量误差来源及消除或削弱方法,给出了精度估算公式,并进行了测量精度估算,给出了适航水深测量的检测方法。
Moving measurement for nautical depth is a new subject in the measurement of engineering.It's very important to evaluate and check the measuring accuracy.The causes of errors and their eliminating measures are discussed from two espacts.The formulas for accurate estimation is given and the checking method for nautical depth measurement is presented as well.
