With all the photographic techniques you are looking for any variations, including moisture content, reflectivity, emissivity and thermal inertia etc. In practice, it does not matter initially what the process is, all you want is variation.
Looked at the photos. Am I understanding correct that the strimmed area is over an experimental ditch recently dug and filled in. Is that the light stripe that shows up on the near IR image and less well on the thermal image?
