Onondaga Creek Relative Stream Temperature Raster, Stormwater Site, July 2017

This is one of three rasters 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 July 19, 2017 at 15:30 EST. It includes 14 images with digital numbers manually adjusted in Adobe Photoshop, georeferenced, and stitched together. 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 stormwater from a culvert 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.
