Learning About Maps

  • Geologic Maps
    Great site to learn how to read a geologic map. Joint effort of the USGS and the National Park Service.
  • Reading Topoographic Maps by James R. Chaplin
    Well organized explanation to help you read a topographic map, including scale, latitude & longitude, range, section, contours. Also inlcudes exercises for teachers.
  • Topographic Map Symbols
    Every symbol for every map! It's here; there is so much that it can be overwhelming. Look for the type of feature (coastal, contour, glacier, mine, building, etc.) and go from there.
