- Urban Landsat: Cities from Space (external site)
- 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 30×30 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. A few are significantly larger.
