All the satellite pictures you can eat

http://srrs.chelys.it/en/

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)
