Background:

Water around the offshore area of Zhuhai Delta island is very shallow where large ships are unable to access. It would take lots of time and effort if surveyed by traditional manned boats, and both the data quality and the safety of surveyors are not promising.

 

Equipment:

ME70 surveying and mapping USV

Sounding instruments

 

Result:

The island about 1 square kilometer, the surveyors set up survey by blocks and the total length is about 28km. It took the USV 2 hours to conduct the autonomous bathymetric and other mapping services.
