Data, data everywhere

We received an email from long time VerySpatial friend Michelle about the release of the full library of Landsat data. We touched on the fact that Landsat 7 was freely available a while back, however you can now access the full 35+ years of Landsat 1 through 7. To access this data head over to the USGS Global Visualization Viewer (GloVis) or the EarthExplorer. If nothing else, the USGS just made remote sensing class projects so much easier.

Earlier this week another US agency, the Census Bureau, posted the 2008 TIGER/Line Shapefiles for road networks and addresses. This is a very large dataset that is broken into many pieces, but I haven’t had a chance to play with it yet. For the most part the data is generally used is small areas where only one or two pieces are needed. However, some folks may need to have access to larger areas, so if anyone goes through the process of joining the data or creating a web service of the data let us know so we can point everyone to it.
