Data/Solution

ASTER and Landsat
http://lpdaac.usgs.gov
An archive that includes ASTER and Landsat data (and MODIS--see below). ASTER is available at US$60 per scene, or at no cost, depending on the type of product you order (all "higher-level" products are free and this should work well for most people, especially the Surface Radiance product--see the Custom ASTER Data link). Landsat is about US$600 per scene. Recommend you use the "GloVis tool" (also called the Browse Viewer) for locating the scenes of interest as it is much friendlier than the alternative.

University of Maryland
http://glcf.umiacs.umd.edu/index.shtml
The Global Land Cover Facility, University of Maryland. Provides no-cost Landsat data (and also other products, including MODIS)

University of Michigan
http://www.bsrsi.msu.edu/trfic/
Tropical Rain Forest Information Center, University of Michigan. Low cost Landsat data, including very recent scenes. Focus is on tropical areas but some others are included. Some radar data are also available. (US$25-50)

MODIS Land Global Browse Images
http://landqa2.nascom.nasa.gov/cgi-bin/browse/browse.cgi
The MODIS Land Science Team has developed coarse 5km versions of selected products to enable synoptic quality assessment via the internet. The coarse spatial resolution products are projected into a global coordinate system defined with pixel sizes corresponding to 20km in the Hammer-Aitoff projection (except for the Sea Ice products that have 14.15km pixels defined in the Lambert Azimuthal projection). These global browse images are generated with fixed contrast stretching and color look-up tables to enable consistent temporal comparison. This web interface has been developed to support interactive selection of browse products and zooming and panning at 5km resolution. The global browse images available on this web site should not be used for scientific analyses.
