Contact Rationalizing and Map Corrections Software

Posted by Irina Tabakina

Chesapeake Technology Inc. (CTI), a producer of real-time sonar acquisition and GIS based processing software for seafloor mapping, announced two new capabilities that it claims will allow users to better organize sonar contacts and improve sonar mosaic accuracy. New Contact Rationalizing, available on SonarWiz version 05.06.0052, is designed to allow a user to combine contacts into a single merged target with an average position. Also available with a software update is the Map Corrections feature. Similar to the Contact Rationalizing tool, it allows users to select a common target on separate sonar files and calculate the offset between an average position. The Map Corrections tool goes an additional step by then applying the offsets to the sonar files’ navigation thereby improving the accuracy and image of the sonar mosaic.
