Thermal Infrared Image Interpretation


Roads: Roads usually appear lighter because they have a higher radiant temperature and have a greater emission of energy.
Natural and man-made vegetation: Vegetation appearances different because it may be an indication of vegetation health or moisture content.
Sidewalks and Patios: Similar effect observed in roads.
Storage sheds in backyards: Some storage sheds may be reflective and hence emit more energy than a shed that is painted darker.
Automobiles: It depends if the car is in the on position or has recently been turned off. The engine emits energy and hence will show lighter compared to the back portion of the car.
Bright spots on many of the roofs: This could be a chimney or some type of vent that releases heat from the house.
