Kodiak Electric Association - Renewable Energy Project

KEA Logo Left

The A World Bridge™ Program at Kodiak Island Borough School District began performing aerial inspections for the Kodiak Electric Association on Sept. 28, 2016. Students from the Unmanned Aircraft Systems - Scientific Applications, and NASA CitySmart projects participated in the mission planning, preflight checks and image/video capture. Data currently being processed includes imagery from the KEA Wind Turbines located on Pillar Mountain.

The image below represents the waypoint map programmed into the UAV’s computer for autonomous flight, and designed to capture 215 high-resolution images as the aircraft follows the transects. This part of the mission resulted in the image analysis and development of an orthomosaic - georeferenced map of the current KEA Wind Turbine farm.

Orthomosaic - 5cm/pixel, converted to .jpg: Notice that generator and blades were blurred due to turning to face wind, so the composite mosaic image does not represent static wind turbine image.
