Research Assistant - Sumac Geomatics


Callum Walter completed a B.Sc.E. degree in geological engineering at Queen’s University with a special focus on applied geophysics. His capstone design project involved integrating multiple geological and geophysical datasets into 3D virtual reality platforms for enhanced interpretation. Concurrently, he competed and presented in the International Imperial Oil Barrel Competition. In 2016, he started a M.A.Sc. in applied geophysics at Queen’s University working with Dr. Alexander Braun and Dr. Georgia Fotopoulos, and was upgraded to the PhD program in September 2017. His thesis investigated how to reliably integrate an unmanned aerial vehicle (UAV) with a high-resolution optically pumped magnetometer for enhancing magnetic data collection in the mineral exploration industry. In addition, he completed a MITACs internship within this thesis, working alongside Sumac Geomatics Inc. in Thunder Bay, Ontario, Canada. This collaboration resulted in the successful integration of a UAV-magnetometry system and the reliable collection of magnetic data. This survey proved the feasibility and performance of the UAS-based magnetic system with only 1% of data not meeting industry standards. One publication from this work is currently in review. Callum won numerous awards and scholarships including a NSERC graduate scholarship, Ontario graduate scholarship, the Society of Exploration Geophysicists (SEG) Lucien Lacoste Award and a Canadian Exploration Geophysics Society (KEGS) scholarship.

Todd Domney moved to Thunder Bay Ontario from Auckland New Zealand to complete his studies at Lakehead University in 1989. Following a brief stint with the Ontario Ministry of Natural Resources he co-founded Sumac in 1996 providing forest growth and yield surveys. Serving as CEO since 2011, Todd has overseen the growth of the company from its forestry roots to a full stack remote sensing services provider. Today, Sumac serves a diverse client base in the forestry, mining and engineering sectors.
