Teledyne Optech said it will attend the Shallow Survey 2015 conference September 14-18 at Plymouth University in England, where a current user of the Optech CZMIL Coastal Zone Mapping and Imaging Lidar will make a presentation comparing various lidar bathymeters.

 

With the conference focusing on high-resolution surveys in shallow waters, Teledyne Optech said it expects CZMIL Nova to draw attention for its ability to detect objects as small as one cubic meter in water up to 25 meters deep. CZMIL Nova has also expanded the list of coastlines that can be surveyed with lidar, thanks to advanced electronics and data processing techniques that let it survey regions with waters too turbid for other lidars to penetrate. This bathymetric surveying solution is now available even to smaller agencies, which can borrow the system for short surveys through the CZMIL Project Program and install its newly redesigned hardware into small twin-engine aircraft.

 

The presentation “A look into the performance of bathymetric lidar systems” will be given by Chris Macon of the Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX). JALBTCX and Teledyne Optech have worked together for 25 years to advance bathymetric lidar technology, resulting in CZMIL’s advanced capabilities. JALBTCX spent the summer testing several types of bathymetric lidar sensors, and Macon will discuss their results.

 

Teledyne Optech exhibit examples of bathymetry work from CZMIL in turbid water in Asia and Lake Michigan, where HydroFusion’s Turbid Water Module improved bottom detection even in locations with inflowing rivers. In the clearer conditions around Hawaii, JALBTCX performed a production survey of over 1,500 kilometers of coastline with CZMIL, ranging from 300 meters inland to 1,000 meters offshore in waters up to 65 meters deep.

 

The Optech Titan is also an industry focus due to its multispectral lidar technology, which enables shallow-water bathymetry, high-density topography/environmental mapping and vegetative analyses in a triple-wavelength configuration.

 

Finally, coastal management authorities can learn about how the Optech ILRIS-MC terrestrial lidar recently helped survey Sydney Harbor in partnership with a multi-beam echosounder. Teledyne Optech  said this watercraft-mounted solution is proving a rapid and inexpensive way to survey critical sections of shoreline in extreme detail, both above and below the waterline.
