Summary
These georeferenced thermal infrared images of Mississippi River navigation Pool 8 were 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 mosaic images for the entire pool.
