Terra Server, Microsoft. This site uses U.S. Geological Survey aerial photos around the world. You can search sites by typing in the name of a location, choosing a location from a world map, or choose from a gallery of famous locations. You can use the photos to show what various types of landforms look like from the air.
Color Landform Atlas of the United States. John Hopkins University Applied Physics Laboratory. This site lets you select any state in the United states. For each state there are various map options including a shaded color relief map, a shaded color relief map with county boundaries, a black and white shaded relief map, detailed maps of areas within the state, a satellite image, historic maps, and a post-script map. These maps are wonderful tools for illustrating geography or physiography within each state. Landforms and the manner in which landforms change across each state are wonderfully shown in shaded relief. Links are also provided to other web sites to provide more information and facts about the state chosen.
Tapestry of Time and Terrain, U.S. Geological Survey. 2000. A great site for visualizing the connection between bedrock geology and physiography (landscapes) and also for illustrating the distribution of rocks of different ages around the United States. The map on the front page is a combination of a 3-D shaded relief map and a geologic map. The Two Maps option shows each map separately and then merges them together using a Quicktime® plug-in. The Description of Features Option lets you zoom in on selected physiographic regions shown on the map and provides specific information about those regions. The Rock of Ages option shows the legend (explanation) for the geologic map (classified by intervals of geologic time). You can choose a time period to see where rocks of that age are exposed at the surface in the United States. There is a short description of the rocks and fossils from that time period, and a series of options for zooming in on specific regions. The web preview is also available on CD from the USGS for a low cost.
