Chesapeake Technology Inc. (CTI), a producer of real-time sonar acquisition and GIS based processing software for seafloor mapping, announced two new capabilities that will allow users to better organize sonar contacts and improve sonar mosaic accuracy.
New Contact Rationalizing, available on SonarWiz version 05.06.0052, allows a user to combine contacts into a single merged target with an average position. Customers have indicated that this new tool has the potential to speed workflow significantly.
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.
"Map Corrections was something requested by several large survey companies and it has been well received especially in areas like Alaska where high currents are common and accurately positioning a towed sonar is extremely difficult,” said John Gann, Vice President of Software Development at Chesapeake Technology, Inc.
CTI said it is committed to ongoing improvements to its SonarWiz mapping software and has several new releases monthly. The new Map Rectification and Contact Rationalization features are the result of customer requests. The new release of SonarWiz is free to all customers who have a current Extended Maintenance Agreement.
