| Abstract: | Sound Velocity Profile(SVP)correction is a main error source in multi-beam survey.The principle and method of sound velocity correction in multi-beam surveying was described.By means of Visual Basic or Excel,the calculation process of position and depth of seabed point along sound profile was simulated.The reason and extent of distortion of sea-bed due to the SVP correction were illustrated and explained.According to theory of error propagation,the error analysis of multi-beam survey relative to sound veloc... |
