Important! This list isn't exhaustive, nor was it intended to be. Its purpose is to provide a starting point when beginning to track down sources of digital geospatial data and attributes related to the US. It isn't meant to suggest one data set or source over another. I've tried my best to bring you as close as possible to the data and metadata. Please expect some duplication of links. At this time there is no "major" concerted effort being expended on developing this page though I do tinker with it from time to time.
