The Landsat Program - Data
More Free Data
- NASA Stennis Space
Center's Landsat GeoCover Data Site
- Worldwide mosaicked Landsat data tiles in MrSID format from circa 1990
and circa 2000. Free, courtesy of NASA SSC. Important
note: this imagery should only be considered as imagery, NOT as data.
Creation of this mosaic involved data resampling, data blending, color balancing
and data compression, i.e., the "digital numbers" that
remain no longer have fidelity as reflective measurements made
by the satellite.
- Urban Landsat: Cities from
- A website featuring Landsat images of 77 international cities published
by the Socioeconomic Data and Applications Center (SEDAC). Each
city is linked to a jpeg image of a Landsat visible/IR composite collected
by Landsat 5 (pre 1999) or Landsat 7. Most of the image areas are 30x30
km but a few are larger. All images are shown at full resolution (30 m pixel)
so the scale (on screen) is equivalent. The jpeg compression causes significant
loss of fine detail from the original image. Most of the images are about
200K (~40 seconds via 56K modem). A few are significantly larger.
