Listed in CIOOS Pacific
Description
What - Orthomosaics derived from RPAS Imagery - Digital Elevation Models derived from RPAS Imagery - Photogrammetry LAS points and other elevation derivatives - see document for details - Vegetated island areas - created from the photogrametric point clouds When - Data were collected between 2015 and 2018 Where - The data were collected on the Central Coast of British Columbia, Canada. - The data cover 100 islands sampled within the Calvert Island Region.
How -The data were collected with Phantom 3 Pro RPAS. -The data were georeferenced with a Topcon GR5 Differential GNSS. -The data were processed with the SfM software Pix4D Mapper. See additional details in the attached methodology document. Who -Luba Reshitnyk, Keith Holmes, and Wiebe Nijland collected the data.

The orthomosaics were created by Luba and Keith. Wiebe calculated the derived terrain and vegetation metrics. Why The 100 Islands program focused on understanding the relationship between marine subsidies and the theory of island biogeography.
Research questions were focused on understanding the relationship between island structure (shoreline, size, vegetative cover) and local biodiversity (terrestrial plants, mammals, passerine birds, invertebrates and sea wrack) The orthomosaics and 3D surface of each study island were used to derive data products such as digital elevation/surface models, island area, vegetated area, and canopy height models.
