Goals for Imagery Exercise

Understand how an imagery system represents

• differences in spectral sensitivity
  • panchromatic
  • "natural" color
  • false color (from bands out of the visible range)
• differences in resolution (and scale)
  • really crude satellite sources (1km?)
  • what we had to put up with (30 m)
  • what is coming (2 m now, 1 m soon) [the sample is of Bangkok from a Russian platform; another sample from this source around the Atlanta Stadium]
  • air photographs (flight height, scale and distortions)

Getting a feel for interpretation

• Urban objects
• Land use
• Land cover
