Color photography is not commonly used in aerial photography because the blue wavelengths are badly scattered by small particles in the atmosphere, including water vapor.

Color Infrared photography avoids the blue spectrum entirely. A color shift takes places
so that the near infrared part of the spectrum from 0.7 to 1.0 microns is shown with red,
the red wavelengths are shown with green, and the green wavelengths are shown with blue.
All photographic images exhibit distortion caused by the central perspective of the camera. An
orthophoto removes this distortion to create a more map-like perspective.
The Landsat MSS scanner acquired imagery of the earth at about 79 meters per pixel over four
bands. One band showed the near infrared part of the spectrum.
Landsat TM, a higher-resolution scanner first used on the Landsat 4 satellite, produced 4 images
at 30 meters per pixel and
SPOT, a french satellite, included a 10 meter panchromatic band.
The SPOT multispectral scanner had a 20 meter resolution but only xx bands.
SpaceImaging launched the IKONOS satellite that has a spatial resolution of about 1 meter.
It acquires images in (insert number) parts of the spectrum.
This is an image from a competing company that offers high resolution images.
