Headed to the floe edge.. This photo, captured at roughly 50' above ground level, shows a group traveling from Arviat, NU to the floe edge on the Hudson Bay. While this target is easy to see with a still image, participants found it difficult to see on an iPhone screen. Intense glare from the sun and snow reflection, along with cold conditions causing loss of hand dexterity made it very difficult to search for objects during these conditions. Photo taken by Dylan G.

Participants of all ages commented that it would be easier to fly and see the landscape with larger screens (Fig 5).
Three-dimensional rendering.. This photo captures the power of the three-dimensional meshing produced using UAV images taken at approximately 75' above ground level. Three-dimension meshing, processed by Pixel3D, produced near-real life textures that could be beneficial in hazard mapping and emergency preparedness. Photo generated by Dylan G.

Three dimensional meshes produced from the three coastal mapping regions varied in quality (Fig 6).
UAV weather constraints.. Five years of daily weather observations were assessed for suitability of UAV flight. This graph depicts the number of days (under model 1 and 2) that were deemed suitable for UAV flights.

The most flyable months under the high limits model were May, June, and July, averaging 17 flyable days per month (Fig 7).
