We rely on GPS but we also should have physical maps; not just road maps but topographic maps of our area. There are places to download free ones. Also free location and navigation apps that can be very useful. Do you know how to read a topo map?

Where to Get Free Maps and Apps; and Map Reading

  1. 1. Map Reading and Where to Get Free Topographic Maps and Free Navigation Apps THE GREEN BERET PREPARATION AND SURVIVAL GUIDE
  2. 2. Most of us rely on GPS, whether in our car or via our “smart phones”. However, that requires a number of things to be working: The GPS satellites. Cell phone coverage for the phone. Power. It is always safe to have a physical backup that is only reliant on you and that you know how to use. Why Do You Need Topographic and Road Maps?
  3. 3. There are 30 GPS satellites in geosynchronous orbit. To get an accurate fix, your device needs to receive from three for latitude and longitude. Four to get that plus altitude. Satellites are vulnerable to EMP and to being destroyed. Why Do You Need Topographic and Road Maps?
  4. 4. Download the contour map for your area for free, then print it out, or order the map sheets. Click here or on image below for USGS free downloadable topo maps. Map THE GREEN BERET PREPARATION AND SURVIVAL GUIDE
  5. 5. Learn how to read a contour map When you look at a topo map, you immediately see that it’s different than your road map. Features on it include: Roads, buildings, boundaries, railways, power transmission lines. Water: lakes, rivers, streams, swamps, rapids, kraken, etc. Relief: mountains, valleys, slopes, depressions, ridges, knolls, gnomes, etc. Vegetation: forested or clear areas, orchards, vineyards, Ents, etc. Toponymy: a fancy word for the names of the various things on the map. Use the map legend to learn how to use the symbols, colors and lines on the map. Scale is the relationship between size on the map and in the real world. Everything always looks a lot closer on a map than when you’re walking. Reading a contour map
  6. 6. Legend It gives you a guide to the various symbols on the map. The types of roads will be defined in the Legend. Contour lines This gives you an idea if elevation. If you trace a contour line on the map, you are tracing a line of equal elevation. If you walked that line, you will not go up or down. Check the legend for the contour interval—this is critical. There’s a big difference between a 10 meter contour interval and a 50 meter one. As you go from one contour line to the next, that is the contour interval difference. The closer lines are, the steeper the terrain. When they’re piled on top of each other, that means a cliff. Do not walk off it. If they are very far apart, that equals relatively smooth terrain. Notice how counter lines always dive in toward streams and rivers. Reading a contour map
  7. 7. The key to using a map is orienting it to the terrain. While there are many field-expedient ways of doing this, the easiest is to orient using a compass. Next easiest is to use roads or easily identifiable terrain features around you. Depending on where you live, you might have useable boundaries that can keep you oriented. For example, in Boulder, CO it is easy to tell which way is west: just look for the big mountains. On Hilton Head Island, the Atlantic is east, the Intracoastal is west. Reading a contour map
  8. 8. Always put your contour map in a waterproof map case. A rule of survival is: what can get wet, will. Click on image to get the one below. Note it has a “dummy cord”. Always tie critical things off to you. Another rule of survival is: what can get lost, will. Map
  9. 9. I have the one below tied of to my survival vest. I also have various smaller, survival compasses on different gear. Compass
  10. 10. Keep a road map in your car. The image below is of the two maps I keep in my Jeep, safe under a rubber map just behind the driver’s seat. The state map of TN has contour maps for the entire state and surrounding area. I recommend getting the one for your area. Click on the image to get the Road Atlas. Road Map
