The University of Maryland's Global Land Cover Facility Earth Science Data Interface provides the means to download Landsat 7 data (30m resolution) from almost any land location on the planet. The data is in a rather fiddly form (separate 60Mb non-normalized GeoTIFF files for each channel) so I really need to write a little program to put them into a format I can use with BlueMarbleViewer.
My blog has been somewhat geeky lately, so here are some pictures of cute kittens.
