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 United States Department of Agriculture Natural Resources Conservation Service has compiled detailed soils data for approximately 95 percent of the counties in the United States. The soils data contains information such as the texture, drainage, depth, and chemical characteristics of the soil. This data can be accessed by reviewing hard copy Soil . . . → Read More: SoilWeb
The Geologic Map of North America was published in 2005 by John C. Reed, Jr. (USGS), John O. Wheeler (Geological Survey of Canada), and Brian E. Tucholke (Woods Hole Oceanographic Institution). This is an amazing piece of work that covers the entire continent of North America at a scale of 1:5,000,000. The map . . . → Read More: Geologic Map of North America
Update 11/28/2011 Seamless Topo Maps - I have released a seamless version (without the map borders) version of the USGS Topographic Map layer for Google Earth. In addition to removing the map borders, hill shading has been added using the 10-meter National Elevation Dataset (NED), which greatly enhances the topography and makes it possible . . . → Read More: USGS Topographic Maps
**UPDATE 8/13/2011** – I have made a couple important updates. First, I have released a global version of the very popular 90-meter terrain map. I have also relaxed the licensing restrictions to allow for commercial use. See below for more details on both of these changes.
There are many ways to . . . → Read More: Terrain Maps
The U.S. General Soil Map consists of general soil association units. It was developed by the National Cooperative Soil Survey and supersedes the State Soil Geographic (STATSGO) dataset published in 1994. It consists of a broad-based inventory of soils and non-soil areas that occur in a repeatable pattern on the landscape and that can be . . . → Read More: General Soil Map of the United States
