WEEK 3




Questions1. Provide a brief description of why the following features appear as they do in this thermal infrared image:

RoadsNatural > they have lighter/ brighter color because the temperature is hotter.


Man-made vegetation>they have lower temp or no heat that is why they have darker color shades.


Sidewalks and patios> same as te roads it retained more heat during the day so the temperature is higher thats why they are bright.


Storage sheds in back yards>the temperature from this barns are low just like the house so they would be represented in a draker color shade.


Automobiles > they would appear as dark shades but their hood will have hot spot so that part of the vehicle will be white.


Bright spots on many of the roof tops > this will reperesents chimneys or heat vents.

  1. Infrared is reading the heat in the veg/soil and why would the house/shed temp be lower. You have to think thermally...hard I know.
