Combined Laser/Multibeam Sonar Survey of Sydney Harbor

Combined Laser/Multibeam Sonar Survey of Sydney Harbor
Teledyne Optech has been a world leader in the design, development and manufacture of advanced lidar instruments for 40 years. In the last few years Teledyne Optech and its sister company Teledyne RESON developed a full and seamless integration between their sensors, the motion-compensated ILRIS-3D laser scanner and the SeaBat 7125 Sonar System, through the PDS 2000 software. The ILRIS Motion Compensation (MC) option was developed to let surveyors use the normally static ILRIS dynamically by combining it with a Position and Orientation System (POS) and Global Positioning System (GPS) receivers. The resulting system is integrated into a mobile mapping system and enables much more effective mapping in wide and complex terrain. This type of mobile laser scanning is now at the cutting edge of coastal survey technology because it allows surveyors to easily survey coastlines directly from a boat and is particularly useful for mapping long or inaccessible coastal areas. This presentation will explain the integration of the ILRIS and SeaBat sensors and showcase several applications in the last few years from Europe to North America to Australia. The survey in Sydney, Australia is the most recent survey made and shows the perfect match between the underwater data from the sonar and the shore data collected from the lidar scanner.
