Things You'll Need:
- Recent topographic map
- Map compass with clear baseplate
- Pencils
-
Step 1
A basic knowledge of topographic maps is necessary to orient with a map and compass. If you've never worked with these tools before, learn to read them before attempting to find your position outdoors.
-
Step 2
Look at your surroundings and pinpoint two landmarks that are also visible on the map. Hills or mountain peaks work well for this, but stream convergences, observation towers and similar objects also work. Circle the two landmarks on your map.
-
Step 3
Take a compass bearing on each of the two landmarks and write down the numbers on the map margins. To take a bearing, point the arrow or forward part of the baseplate toward the landmark and rotate the dial until the north marking lines up with the north compass needle. Look at the line on the compass dial--it should line up with one of the degree numbers written on the face. This number is your bearing.
-
Step 4
Lay the map flat and align the north mark with the north needle on the compass.
-
Step 5
Rotate the compass dial to the bearing of one of the two landmarks. Place the compass on the map and align the north mark on the compass with the north needle (and the map's north mark, if it is aligned properly). Keeping the mark and needle aligned, place the edge of the compass baseplate on the landmark and draw a line using the plate as a ruler.
-
Step 6
Repeat Step 4 with the bearing from the second landmark. When you are finished you should have two lines that intersect. Circle where they cross over; this is your position.
