This doesn't entirely eliminate the need for "boots on the ground," so to speak. For example, in a building with a steam distribution system, you have to check boilers, lines and steam traps inside the buildings and steam tunnels from the ground. On the other hand, the distribution and condensate return lines are best surveyed from the air. "The entire system can be flown, a mosaic thermal image produced and the areas with suspected problems can be pinpointed and documented. Owing to recent developments in infrared technology and the availability of high thermal sensitivity/high spatial resolution (large format) thermal imaging systems mounted on an aerial platform, the on-ground survey has become outdated."*
So how does it work? Well, it's very similar to how regular aerial photographs are made. A plane flies over a specified area with a camera mounted to the airframe and oriented looking straight-down to the ground (NADIR). The imagery is stored on a computer hard drive and later post-processed. Where aerial infrared thermography differs from aerial visible photography is the time of day when the survey occurs. IR aerial thermography is done at night to "see" sources of heat and the relative differences in heat from one object to another.
