Hi,


For some reason it didn't come to my attention until recently (less than a year ago) that the entire Landsat imagery plus a lot of data from other Earth orbiting spacecraft is freely available for download at earth explorer . Maybe this is because for a long time it was more difficult to find good and freely available global maps (or get data to make maps) of the Earth than it was for other planets/satellites - I somehow was under the impression that the vast majority of Earth imagery was commercial.


The Earth is visually a really spectacular planet (in my opinion possibly even the most photogenic body in the entire solar system) so it's possible to get spectacular results by downloading some of this data. The data can be selected by spacecraft, instrument, location, months/years, cloud cover percentage etc.


Data is available from several Landsat satellites but the best data is from Landsat 7; Landsat 5 is also good. This is multi spectral data with a resolution of 30 meters/pixel. Here is an experimental and spectacular 12 frame mosaic.
