Seamless Topographic Map Mosaics are great for planning hiking/bicycling trips, environmental research, land use planning, and many other uses. They also make a great base map for using Google Earth in off-line mode for those times when a high speed wireless connection is not available.
The maps are available in downloadable bundles . . . → Read More: Seamless Topographic Maps for Google Earth
The USGS has announced a schedule for release of over 100,000 historic topographic map quadrangles covering 32 states by the end of 2011. This is an amazing resource for anyone interested in studying the history of an area in the United States.
Kansas is the first state in the release schedule . . . → Read More: USGS National Map Historic Quadrangle Scanning Project

The Perry-Castaneda Library Map Collection at the University of Texas at Austin has begun an ambitious project to scan all available pre-1945 USGS topographic maps for all US states that don’t currently have them available online. They are starting with Texas and working their way out from there. As of today, Texas, New . . . → Read More: Nationwide Historic USGS Topo Map Scanning Project
On Saturday, February 27 at 6:34:14 UTC, a magnitude 8.8 earthquake occurred near Maule, Chile. News is just starting to come in so not sure how much damage there will be from this earthquake.
I will start working on a collection of map and earthquake data overlays for Google Earth. I will continue . . . → Read More: Chile Earthquake Maps
