“Applications of topo-bathymetric lidar in the coastal zone”

 Previous airborne bathymetric lidar sensors were large and expensive and concentrated on mapping as deep as possible using a combination of near-infrared and green lasers. This talk will present the Chiroptera II, a new shallow water topo-bathymetric lidar sensor owned by the NSCC that is designed to collect seamless elevation data from land to the submerged terrain under coastal or freshwater. In addition to collecting the elevation at high resolution ~ 1m and vertical precision ~ 15 cm, the intensity of the reflected green laser also provides insights into what is on the seabed and can be exploited for mapping. A 60 MPIX RCD30 camera capable of capturing NIR and RGB bands of imagery is co-aligned with the lidar sensor to provide additional data that can be directly georeferenced and used with the lidar for mapping and engineering applications. The AGRG Coastal Research Team have conducted several surveys in the Maritimes since 2014. Various applications of these data will be presented including mapping submerged aquatic vegetation, input to hydrodynamic model simulations, and shoreline sensitivity mapping.


Dr. Tim Webster
Research Scientist

Centre of Geographic Sciences (COGS) – NSCC

Tim is a research scientist with the Applied Geomatics Research Group at the Nova Scotia Community College in Middleton, NS. His research focus is mapping, monitoring and modeling processes in the coastal zone. He is the principal investigator of a recent Canada Foundation for Innovation Award to obtain a topo-bathymetric lidar to support coastal and aquatic research. He is the 2010 recipient of the Gulf of Maine Council Visionary Award, and obtained his PhD from Dalhousie University in 2006, MSc from Acadia in 1996, Advanced Diploma from the College of Geographic Sciences (now part of NSCC) in 1988, and a BSc from UNB in 1987. He was a faculty member at the Centre of Geographic Sciences teaching remote sensing and GIS from 1991 to 2000 until moving into the role as research scientist.


OUR OCEAN PLAYGROUND- Education Day 2016


Wednesday, November 23, 2016 | Halifax World Trade and Convention Centre 1800 Argyle Street, Halifax Nova Scotia

Be part of an exciting event focusing on experiential ocean education. You will have a chance to participate in interactive investigations relating to 4 key ocean sectors in our province, led by regional experts from industry and academia. Participate in hands-on experiences that will link science, technology, engineering and math, with concepts relating to the ocean economy and ecology, careers, innovation & entrepreneurship, and local communities.


All types of farming rely on a good understanding of lifecycles and ecosystems. Learn more about the controlled farming of freshwater and marine fish and aquatic plants, and gain insight into how this growing industry is contributing to the economy of small coastal communities across our region. (French/English)

Marine Renewable Energy

All movement is energy. Find out how energy is being harnessed from tides, waves and currents. Meet local innovators who are on the cutting edge of this technology, and build efficient turbines that best balance the need to capture energy with the interests of preserving aquatic ecosystems. (English)

Marine Optics and Acoustics

Explore how sight & sound and the behaviour of light and sound waves behave and vary in marine environments. Understand how local researchers and innovators use this science to develop technologies that help us to see and hear throughout the ocean – and see how this information helps to inform activities relating to ecology, the economy, and global societies. (English)

Shipbuilding and Boat Building

Investigate how the properties of materials and ocean water influence the design and construction of marine vessels. Explore cutting-edge technologies and careers that are emerging from these booming sectors, and discuss the impact on communities and the economy across the province. (French/English)
