Front 34

How do you orient a map with a compass?

Back 34

With the map flat on the ground, place the straightedge (on the left side of the compass) along the magnetic north arrow on the declination diagram so that the cover of the compass is pointing toward the top of the map. This will put the fixed black index line of the compass parallel to the magnetic north arrow of the declination diagram
- Keeping the compass aligned as directed above, rotate the map and compass simultaneously until the north-seeking arrow is below the fixed black index line on the compass. Your map is now oriented.

Front 35

How do you orient a map using Terrain Association?

Back 35

- Identify prominent terrain features on the map that you can find on the ground.
- Align terrain features with the map. If there is a tower to your right front, then orient the map so that the tower is to your right front. If there is a road off to your left, then ensure the road on the map is parallel to the road on the ground. Once all of the features are lined up, your map is oriented

Front 36

How do you determine your position using the "Location by inspection" method?

Back 36

- You are standing in the vicinity of several prominent features which can easily be located on the map. By orienting the map and estimating your relation to these features, you should have no difficulty in determining your location.

Front 37

How do you determine your position using the "Location by one-point resection" method?

Back 37

- Identify the linear terrain feature that you are located on or near in respect to the ground on your map.
- Identify a prominent feature on the ground and locate that feature on your map.
- Using the compass-to-cheek technique, sight in on the feature and read the magnetic azimuth
- Convert the magnetic azimuth to a grid azimuth.
- Convert this grid azimuth to a grid back azimuth.
- With your protractor, plot this grid back azimuth from the feature on the map and extend it until it crosses the linear feature.
- Conduct a map inspection to verify your resection.
- When selecting a terrain feature, choose one that is perpendicular to the axis of the linear terrain feature so that when you plot the back azimuth on the map, the line will cross the linear feature more or less at a right angle.

Front 38

How do you determine your position using the "Location by two-point resection" method?

Back 38

-Select two prominent features on the ground whose positions can be located on the map. These features should be at least 30o but not greater that 150o apart.
- Using the compass-to-cheek technique, determine the magnetic azimuth to each object
- Convert these magnetic azimuths to grid back azimuths.
- With your protractor, draw the respective back azimuths from these two points on your map.
- Extend the azimuth lines from these two points until they intersect. You are located at the point where these two lines cross.
- Conduct a map inspection to verify your position
