Precision flight: thunder Bay forest consultants acquire UAV.

Author:Ross, Ian

A Thunder Bay natural resource consulting firm is taking to the skies with the purchase of its first unmanned aerial vehicle (UAV) for aerial imaging and mapping applications.

Sumac Forest Information Services took delivery of its Lancaster Hawkeye MK III over the Christmas holidays and began test flights of the vehicle produced by Precision Hawk of Toronto. "We've been looking at this technology for about a year and a half," said Todd Domney, one of three co-owners of the 19-employee firm established in 1996.

Adding the UAV is a part of a larger technological shift for the company which began collecting ground-based data to support forest management and now has been increasingly moving into high-end digital mapping.

"Getting into the aerial imaging is something new for us." said Domney.

"We were a bunch of timber cruisers and we were very good at it but the industry downturn and the shift in focus with the Ministry of Natural Resources back into the inventory business with the EFRI (enhanced forest resource inventory) program has really changed the focus for us."

At an industry trade show, Sumac started discussions with two UAV makers before they settled on the Precision Hawk as their vehicle of choice.

Formerly known as Winehawk Labs, Precision Hawk had been extensively working in the Niagara Peninsula. flying the vineyards and orchards to monitor crops.

"In chatting with these guys I soon realized that precision agriculture stuff has a huge crossover into forestry and other kinds of applications." said Domney.

Weighing three pounds and measuring three feet from nose to tail, the aircraft is described as a "fly and forget" platform.

A fully autonomous vehicle, it can be simply hand-launched by a user and programmed to fly a boxed area of interest.

An internal intelligence and guidance system assesses weather conditions and wind direction and the aircraft sets up its own flight pattern to gather the appropriate data that can be transferred to a software platform.

With a price tag of $40,000. Domney said it's reasonably affordable compared to other high-end systems.

Sumac's UAV is outfitted with a camera and an 18.5 mm lens for high-resolution photography.

If clients demand it. Domney said, they can attach Lidar, hyper-spectral. visual and thermal imaging devices and a host of other sensors.

The company plans to hold demonstrations for clients in the spring. Technology has changed the whole dynamics of how forest stands are...
