LandSat 7 is a satellite of the USGS Landsat Project. The satellite is equiped with an ETM+ instrument that is an eight-band multispectral scanning radiometer capable of providing moderate resolution image data of the Earth's surface.

The band information is combined to produce an image, and by using different bands you can get images that represent human eye perception, thermal, infrared or other visuals.

LandSat 7 data is available globally at a scale where you can pick out many prominent features in the landmass. The maximum resolution of the ETM+ is 15 meters per pixel on the panchromatic band.

NASA Learning Technologies is in the process of creating LandSat 7 imagery. The current focus is on getting vivid coloring for the 30 meter per pixel resoltion and as such, that is the current maximum resolution. Pan-sharpening will be done later to generate the 15 meter per pixel resolution. See NLT Landsat Processing Techniques for information on how the data is being processed.

Visible

  • The maximum resolution is 30m per pixel.
  • Uses bands 3, 2, 1

OnEarth is a project of the NASA Jet Propulsion Laboratory. OnEarth has asked that World Wind not access the imagery off its servers. In order to see the OnEarth data you must install the World Wind Central Add-on Pack.

Visible

  • The maximum resolution is 15m per pixel.
  • Uses bands 3, 2, 1

Pseudo

  • The maximum resolution is 15m per pixel.
  • Uses bands 5, 4, 2
