Onondaga Creek Relative Stream Temperature Raster, Spring Site, May 2017

This is one of three raster datasets collected during summer of 2017 displaying relative stream temperature data obtained from thermal infrared images collected via a small unmanned aerial vehicle. This site was flown on May 12, 2017 at 15:30 EST. It includes 7 images with digital numbers manually adjusted in Adobe Photoshop and then georeferenced. As this displays relative temperature, higher values (255) indicate warmer temperatures, while lower values (0) indicate cooler temperatures, but exact temperatures are not specified as the photos were digitally altered in Photoshop.

This particular site visualizes the impact of water from a natural spring mixing with main stem stream temperatures.

Drone imagery was flown with an Inspire 1, and thermal infrared imagery was collected with a Zenmuse XT Radiometric thermal camera. Altitude was 61 m AGL and camera yaw was 28 deg.
