Sara McPeak Presents her Research

Tuesday, August 16, 2016

Sara McPeak Master's student Sara McPeak recently gave an oral presentation on her research at a conference in Fredericton, New Brunswick. She attended the 2016 Joint Scientific Congress of the Canadian Meteorological and Oceanographic Society (CMOS) and the Canadian Geophysical Union (CGU) with her supervisor, Dr. Claire Samson. Dr. Samson is also the President of the CGU, and as such played a large role throughout the event. 

Both ladies presented under the section theme Interdisciplinary and other. Sara gave a presentation entitled "Comparing a Miniature Structured-Light Sensor and Lidar for Imaging Rock Walls". Dr. Samson gave the following three oral presentations: 

- Towards a new method of rock mass stress calibration based on tunnel deformation captured by LiDAR imaging

- Geological mapping of mining tunnels using 3D images acquired from a moving platform 

- Student-Led Project for Development of a Small Multi-mission UAV for Geophysical Surveying Applications 

Sara notes that attending this event was very informative and a great experience for her. It marked the third conference of her career. She had previous attended the Propectors & Developers Association of Canada (PDAC) Convention and the Advances in Earth Sciences Research Conference (AESRC) earlier this year. 

Since participating in CMOS/CGU 2016, Sara has been working on another aspect of her thesis. She is using two instruments, the Konica Minolta VIVID 9i non-contact laser digitizer and the Faro Laser Scanner Focus 3D LIDAR, to estimate roughness. Both instruments take images in the form of point clouds. The end goal of this component is to “color code” the point cloud data according to roughness. This will allow her to visualize and map out the locations of smoother and rougher sections of the rock wall she is studying. The wall is located at the Canadian Wollastonite Mine in Seeley's Bay, a village outside of Kingston.
