back to article Three million satellite snaps now free for all

NASA and Japan's Ministry of Economy, Trade and Industry have announced that all Earth imaging data from the ASTER instrument on NASA's Terra spacecraft are now free-as-in-beer. ASTER – the Advanced Spaceborne Thermal Emission and Radiation radiometer – was Japan's contribution to the instruments aboard Terra, and it's been …

      Those are some ridge tiles if they are bigger than 15 x 15 metres.

    Nice!

    Me, and many other scientists can really use a huge database of images to test our algorithms for seriously big images. We are now moving from "mere" gigapixel images to tens and hundreds of gigapixel (per image), and hope to breach the terapixel level soon. More (free) data to test stuff is very, very welcome.

      Just checked, the resolution is not that high (15m at best) so a swath should be about 4000 pixels wide. Still, some extra multi-band data for extending our algorithms to that domain is always welcome
