20171120 Thermal Infrared Mosaic of Upper Mississippi River, Pool 8 (Celsius)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2021-11-15T00:00:00Z
This georeferenced thermal infrared mosaic of Pool 8 was collected at 0.5 meters/pixel on November 20, 2017 using a mid-wave infrared camera (SC8343, FLIR Systems, Inc., Nashua, NH). This camera was mounted in a Partenavia P68 Observer aircraft and flown at 915m above ground level using a 25mm lens. GPS and inertial measurement unit (IMU) sensors tracked horizontal and vertical position and the IMU tracked sensor orientation (roll, pitch, and heading). These values, along with a 10 meter/pixel resolution digital elevation model, allowed us to orthorectify each frame of thermal imagery to the earth. These orthoimages were then mosaicked into a single image for the entire pool.
