Index to Topographic Maps - 1:100,000 Scale
What this map layer shows: The positions of the intermediate-scale topographic maps that cover the conterminous United States and Hawaii
Background Information
Sample Map The U.S. Geological Survey (USGS) produces topographic maps of the United States at a variety of scales. The intermediate-scale USGS topographic maps are at 1:100,000 scale and are used for land management and planning. These maps include natural features, such as mountains, valleys, plains, lakes, rivers, and vegetation. Contours in meters are used to show elevation. Also included are constructed features: roads, railroads, boundaries, transmission lines, and major buildings. The standard map size is 30 minutes of latitude by 60 minutes of longitude. Detailed information about topographic maps can be found on the USGS Topographic Maps page, and the USGS Digital Backyard has further information on topographic maps and digital cartographic products. The Index to Topographic Maps - 1:100,000 Scale map layer shows the positions of the intermediate-scale topographic maps that cover the conterminous United States and Hawaii. Descriptive information includes the map name and a link to the Terraserver, where the map can be viewed.
