China’s state owned Guangdong Construction Engineering Group (GCEG) has purchased JW Fishers side scan sonar system. The sonar is being used to the map the bottom of various waterways before and after construction projects. It is providing engineers with information on the make up of the bottom (mud, sand, rock, etc.), as well as helping to locate and identify debris or any obstructions. Using Fishers side scan sonar and Sonar View software, GCEG engineers are able to produce detailed maps of the bottoms of rivers, lakes, and the ocean. The sonar images can be displayed on a standard laptop computer or Fishers Splashproof PC with ultrabright LCD display.
