Map and compass navigation pdf

Alright, so everyone knows a few fundamentals of navigation- north is always up, the sun rises in the east, and compasses usually point towards magnetic north. But at some point in time, outdoor enthusiast or not, you'll want to be able to find out where you are, and where you need to go. I decided to create this Instructable after a challenging three day backpack in Olympic National Park, located in Washington State. This means that in July, we found snow as low as '. Great for skiers, but for the casual hiker or backpacker, it makes trips just a little bit more challenging.

Map and Compass Navigation Part 1

Lucky for us, I'm pretty comfortable with rudimentary navigation. In this Instructable, I'll explain to the best of my ability how to use a map and compass to keep you found.

How to Navigate by Map and Compass

The map is your most important tool, as you can always squeak by without a compass not recommended! Right now I'll stick to what kind of map you'll need, and save map features for later. A scale of 1 inch equals 24, inches and line intervals of 50 feet make them pretty detailed. Cons: The 7.

Basic Map and Compass Navigation: How to Get Around with the Old Technology

Many maps haven't been updated since Essentially, be sure your map- -Covers the entire hike. Unfortunately, the maps are difficult to read when compressed to 8.

As you can see, I've only included maps found for Washington State except usgs. If you've got any more favorites I'd love to expand this list. The compass is your second most important navigation tool, but it is also the most important to get exactly right.

Unfortunately, there's not much room for DIY here. Your compass should have specific features, and they're absolutely worth a few bucks extra. It should have: 1. A clear base plate- To see underneath the compass.

A sighting mirror- To sight objects at eye-level. A rotating bezel, marked with degrees in 2 degree increments. Meridian lines- For map use. Declination Adjustment and arrow- to correct for the difference between magnetic and true north. And there are many more features.

Just be sure you at least have the basics. It works great, and is fairly inexpensive. Its more expensive and I still prefer the MC-2 D. This step is pretty simple.

Coordinate Systems

When doing any map work, be sure you ignore your compass needle and declination arrow. Those guys are only helpful when you're using the compass in relation to the world around you. For now, consider it more of a protractor. This is the simplest of the exercises. Imagine your on a mountain lookout. You see another mountain, what heading is it?

How to Use a Compass: Tips and Tricks for Beginners

Open the Compass, and lay it flat on the map. Move the compass so that the base is along point A where you are , and the mirror is along point B the other mountain. Read the bearing at the top of the compass. Any lines that parallel it will work too. Alright, you're on a mission. You know that there's a cave filled with treasure, unmarked on your map, It's NW of your position.

Open the compass and turn the bezel to NW 2.

Orient the compass with the clear part along your current position. The destination is somewhere along the line created by the base of your compass. Before we use your compass, we'll have to set the declination. First, find the declination in your are by visiting NOAA Geomagnetic Data Then, follow the directions that came with your compass to set the declination properly. Now you can take a bearing on a real object.

Choose an object to take a bearing to. Ideally this is something you can do, then reference on a map. But you can practice with objects that are a minimum of twenty feet away. Stand well clear of your computer.

Large, metal objects usually mess up compass readings. Hold the compass outward, level, relaxed, and at eye level.

Close your non-dominant eye. Match the object up in the compass sights. Be sure its level! Turn the bezel until the north red needle is in the declination arrow. Read the heading from the bezel. Give the bezel a spin, rinse, repeat. You know your campsite is only a mile away, at heading 40NE. But how do you translate the heading into an actual direction?

Dial the bearing in on your compass. Turn your body until the north needle is within the declination arrow or box.

Take note of an object on that heading. Choose a peculiar tree, peak, or anything else in your direction of travel.

Head to that object, then re-shoot your bearing. Method 2 Shoot the bearing, then have a partner travel in that direction until he's just at the edge of your sight distance.

Once he's there, tell him to move left or right to get him aligned.

Move to your partner, then repeat. It's a great method if you need to be super accurate.

Introduction to Map- and Compass-Skills Course

Hopefully you just learned four new skills. I'm not an expert, but those few things are enough to keep most people out of trouble. The easiest place to practice is around home If you head out to the wilderness, find a spot where you can pick out a bunch of landmarks. Shoot them with the compass, then compare your bearings to the actual bearings on the map.

I'd love input on this instructable, I plan on using this as a base to build on other topics, like map reading, advanced compass use, and map in hand with GPS.

Remember the best way to avoid getting lost is to stay found. Have fun! Acknowledgments- Mountaineering: The Freedom of the Hills 7th Edition If you're serious about the outdoors, the book is a great reference. There are a lot of different things you can put on your b ug out bag list and there is not really one list of contents that you should travel.

The Idiot’s Guide to Using a Map & Compass

One of the first things you must start prepping for is food, when you begin to consider prepping. You have to do it now, hopefully you have already shaped the battle space of your bug out location to make it easier but if not. So, let's look at finding "North". When taking a compass bearing on the map you will have aligned the compass using the grid lines and your resulting compass reading will therefore be by reference to "Grid North".

This is not quite the same as "True North" but the difference can be ignored.

However when you take your compass off the map it will read by reference to "Magnetic North" and so your bearing will be slightly inaccurate. Therefore before walking off in the direction of the compass bearing you need to adjust from "Grid North" to "Magnetic North".

To do that look at the information section on your map which will tell you the "magnetic variation" for that area. If your map is not a recent one you should update the "variation" using the information printed on the map. Having determined the "variation" adjust your compass bearing. For example the "variation" in the UK Lake District is about 4 degrees.

If your compass bearing off the map is reading say degrees turn the compass housing to add 4 degrees to obtain a magnetic bearing of degrees. In some countries you may need to deduct the variation so check your map! Also in some areas the type of underlying rock formation may affect your compass and whilst this phenomonen is quite rare a little reading up on the area you intend to walk in should reveal any such problems. If you are following a distinct path - taking a bearing for a short leg of the walk and then adjusting for the magnetic variation is not critical but it will be at path junctions and in mist or at night and for longer distances.
