Application of GPS-RTK with All-digital Sounder in Reclamation Engineering
Yuan Shao-hong · Journal of Zhejiang Water Conservancy and Hydropower College · 2009
The application of GPS-RTK,along with all-digital depth sounder inserted by navigation software,is introduced in the paper,which is easy to operate with high efficiency and precision.Take Southern Reclamation Engineering for example,the application of GPS-RTK with all-digital sounder shows its relative advantages in subaqueous topographic survey compared with those in subaqueous cross-section survey.Some aspects resulting in poor precision of subaqueous topographic survey are analyzed and the countermeasures are also discussed.
