Map 17 - Infrared Aerial Photo Map

This is an infrared aerial photo I got from:

In infrared map allows us to see variations in surface/object temperature. Warm objects emit infrared light, and the hotter the surface, the shorter the wavelength, thus you see a corresponding glow (e.g. red light). This enables weather forcasters to notice storms, or rescue workers to locate warm bodies in oceans, or in forests through vegetation or fog.
