This is excellent, great job.<p>I'm currently doing an internship with USDA-Agricultural Research Service(ARS), and was pleasantly surprised at the amount of free meta-data they offer to the public. For instance, I'm currently doing some work with GIS data/display and the USDA makes available soil data and GIS data files of the entire US as well as some other places like Puerto Rico for the public through their data gateway website[0].<p>[0] <a href="http://datagateway.nrcs.usda.gov/" rel="nofollow">http://datagateway.nrcs.usda.gov/</a>
