Fort-Worth Thermal Image

1. Provide a brief description of why the following features appear as they do in this thermal infrared image:

Roads - Bright color.Pavement heats up quicker in the morning and retains heat over night.
Natural and man-made vegetation - medium brightness. Barren ground will hold more heat over night than grassy areas. Lighter ground in the image will appear warmer than darker greener areas.
Sidewalks and patios - bright color. Concrete walkways and patios will hold more heat overnight as well and will heat up quicker in the morning sunlight.
Storage sheds in back yards - dark color. Sheds have probably not been hit by the sunlight yet as the houses are blocking them.
Automobiles – medium dark to full dark. If the cars have been run recently then the fronts will be whiter and if they haven’t they will be darker. Also, cars will appear darker if they haven’t been in the sun yet.
Bright spots on many of the roof tops – roof vents that are metal will attract sun quicker and show hotter.
