has images from MERIS (a conventional optical satellite with about 300 metres per pixel resolution) and also ASAR (a synthetic-aperture radar; 150 metre resolution - great for terrain, cities show up as clusters of bright dots wherever a roof happens to be at the right angle to reflect the radar specularly).
Most of the images have attached KML files, so may show up usefully in Google Earth.
I haven't seen a reasonable gallery of SAR images before. This example (3MB, 4864x7425 JPEG) is a swathe across the north-west corner of South Island in New Zealand; lovely crinkly edges.
http://www.eosnap.com/ is somewhere between a collection of press releases and a blog; it has some more-processed products from the satellite. http://www.eosnap.com/?page_id=2668#asar points to this lovely mosaic of Italy, Slovenia and the Croatian coast (16640x14592 (!!) JPEG) (2080x1824 version)

Date: 2009-08-25 07:08 pm (UTC)Out of curiosity I tried looking at the huge JPEG in a few ways.
Linux Firefox 3.0.6 on a 2GB machine managed to download it and zoom in but with endless swapping; unusable but FF eventually recovered when I closed the tab.
Mac Firefox 3.5.2 on a 6GB machine started to display it but beachballed about 20% of the way in, and eventually I killed it.
Preview.app on a copy downloaded separately had no trouble displaying it, zooming, navigating etc. A bit sluggish but still usable.
Firefox seriously needs to get a grip l-)
