From its launch as one of the ? rst suppliers of PC- based sonar sidescan processing tools 20 years ago,

Chesapeake Technology has grown to become a lead- ing supplier of sea ? oor mapping software. This year, in a major initiative designed to help marine profes- sionals leverage new sonar systems’ most complex
