The primary goal of this collective project is to gather imagery for broad areas of the British Columbia coast in order to map canopy cover of peak kelp biomass. There are multiple end users and partners through MaPP, but the methods and primary goal are the same and therefore we have grouped them into one project report. All flights have occurred during peak kelp growth season (July - September, 2020). The projects are located on the BC Central Coast (project #3007), Haida Gwaii (project #3018 & #3029), the BC North Coast (project #3019, and NE Vancouver Island (project #3020). Imagery resolution varies between 8-10 cm and is the primary data product in order to extract kelp canopy extent.
Project #20-3007-01 was successfully flown on Sept 4th, 2020.
Project #20-3029-01 was successfully flown on Sept 5th, 2020.
Project #20-3020-01 was successfully flown on July 25th, 2020.
