I want to download a bit of Landsat data - two small countries worth - but can't find any way to efficiently do this via GloVis or elsewhere. Where can I just select places on a map (or use my GloVis-exported) scene list to download these in bulk? Given 200MB/scene and the 80 scenes I need, it'll be 15.6 gigs downloaded (and likely around 40 unzippped), but that's not the problem; there just doesn't seem to be a way to do this. [more inside]
