PS. Something that may be of interest and is relevant to this subject is a recent announcement of a successful Canada Foundation for Innovation grant to the NSCC to acquire a bathymetric lidar system. I am the principal investigator on that proposal if you have any questions. Please see the news release below.


NSCC awarded Canada Foundation for Innovation funding to support coastal mapping research
Researcher says opportunities are as vast as the waters to be mapped

For Immediate Release - April 16, 2013

Middleton, NS – Nova Scotia Community College (NSCC) will become the only college in Canada with a research device that can unlock the mysteries off Nova Scotia’s shores thanks to the support of a national innovation award and industry partners.

The Honourable Gary Goodyear, Minister of State (Science and Technology), announced today that the government will invest $798,906 through the Canada Foundation for Innovation (CFI) in a research project that will capture the treasure trove of information that exists in the shallow waters off Nova Scotia’s coastline — known as the “white ribbon gap” due to the challenges of mapping this area.

“ The possibilities are as vast as the waters we will be charting,” says NSCC research scientist and PhD in Earth Sciences Tim Webster. “Our team will be able to map seabed topography by air, unearthing a wealth of data to support initiatives in areas including sustainable harvesting practices, aquatic vegetation health, wave predictions to better define storm surge detail, and nautical hazards plotting.”

Industry partners investing in the research project, including McGregor GeoScience Ltd., Acadian Seaplants Limited, Leading Edge Geomatics, GeoNet Technologies Inc. and Nova Scotia Power Inc., are relying on the project’s equipment and research to be of benefit to their specific business needs.

“Acadian Seaplants’ stewardship of the rockweed fishery will advance even further because we will use the latest imaging technology and high-tech software to identify, much faster, where the rockweed is and how much is there,” says Acadian Seaplants Limited, Vice-President of Research, Alan Critchley.“NSCC’s expertise and new technologies will augment our sustainable resource management practices and enable the adoption of the most advanced scientific tools to safeguard the marine resource.”

The project scope includes the purchase of a new laser system, two new GPS receivers, a boat and extra staffing support. The bathymetric Laser Imaging Detection and Ranging (LIDAR) equipment is able to measure the subsurface topography in oceans, rivers and lakes, offering a safe, cost-effective and efficient means of collecting data in difficult-to-access areas.

This bathymetric LIDAR is unique in that it can be mounted in an aircraft to look down into the water or can be turned sideways and mounted on a boat to measure the detail of the coastline. Repeat surveys can accurately measure erosion after storms or provide important information to infrastructure projects along the coastline, such as cable landing sites.

The award is part of a $12.5-million funding announcement for applied research and business innovation from the foundation’s College Industry-Innovation Fund.

“Canadian colleges are an important player in our national innovation ecosystem,” says Gilles G. Patry, president and CEO of the CFI. “The team at NSCC is showing what colleges can achieve when they have the state-of-the-art research infrastructure they need to conduct top level applied research.”

Canadian Institute of Geomatics 2-day Symposium at COGS in Lawrencetown on Feb. 19-20 entitled "Advances in Positioning Technologies and Applications to Mapping".

Agenda -
The 2 day event will cover the latest in precise positioning technologies and how they are used for mapping and the applications of these data.
Day 1 will cover GPS high precision positioning techniques (theory and equipment) with presentations from COGS faculty and the suppliers of Leica and Trimble equipment. The coupling of GPS and Inertial Measurement Units (IMU) for navigation will be discussed for land, airborne and marine based vehicles.
This precise positioning technique GPS-IMU navigation has enabled advances in high resolution data collection including: 1) mobile mapping (camera and LiDAR systems mounted on a land vehicle), 2) airborne mapping (LiDAR and camera systems mounted on an aircraft), and 3) marine mapping (multibeam bathymetry and sonar systems mounted on a vessel). Experts from TerraPoint (one of the leading airborne and mobile mapping LiDAR companies), AGRG, and BIO will present on these topics.
In the late afternoon and evening of the first day you are invited to bring your hockey gear to get some exercise for the body in the Lawrencetown Rink after a day of exercising the brain. This will be followed by a social hour and dinner at the Mid Valley Motel (reduced rate for delegates of the symposium).
Day 2 will begin with an overview of Canada's Radarsat 2 polarimetric radar satellite, and radar interferometric techniques for precise measurements of change as related to critical infrastructure. These topics will be presented by the experts from the Canadian Space Agency and C-CORE (tentatively). This will be followed by an update from a representative from Digital Globe on the latest high-resolution optical satellites eg. quickbird etc.
The afternoon will be dedicated to demonstrating applications of these new high-resolution data sources with presentations from AGRG and TerraPoint confirmed.
Depending on the number of hockey players and teams, a "final" game may be required to crown the first CIG NS Branch Champion.
