Reference Lines

Determine Azimuth on a Map Using a Military Protractor

• Place Center Point on your Start Point• Using Reference Lines and Grid Lines Align

Protractor in a good North South Orientation• Find Azimuth on Inner Ring of Numbers• Place Small Mark on map at Degree• Using protractor as straight Edge draw line

between Start Point and the Mark you Made This is Your Azimuth line.

Determine your Location on the Ground Using Resection

• Define Resection -Resection is the method of locating one's position on a map by determining the grid azimuth to at least two well-defined locations that can be pinpointed on the map. For greater accuracy, the desired method of resection would be to use three or more well-defined locations.

Determine your Location on the Ground Using Resection

• Orient the map using the compass.• Identify two or three known distant locations on the ground and mark

them on the map.• Measure the magnetic azimuth to one of the known positions from

your location using a compass.• Convert the magnetic azimuth to a grid azimuth.• Convert the grid azimuth to a back azimuth. Using a protractor, draw a

line for the back azimuth on the map from the known position back toward your unknown position.

• Repeat 3, 4, and 5 for a second position and a third position, if desired.

• The intersection of the lines is your location. Determine the grid coordinates to the desired accuracy.

Determine your Location on the Ground Using Resection

Determine a Movement Route using a Map

• Shortest Route (straight Line)

• Most Tactical Route (Stealth)

• Safest Route

Determine a Movement Route using a Map

• Shortest Route– Find an Azimuth and Go

– Terrain?

– Time of Day?

Determine a Movement Route using a Map

• Most Tactical– Wont be Seen By Enemy

– Use the terrain

– Stay away from heavily traveled areas i.e. roads, trails.

– Not necessarily quickest or safest

Determine a Movement Route using a Map

• Safest Route – usually the easiest

– Pay careful attention to terrain

– Stick to improved roads and good trails

– Defiantly not the shortest or most Tactical

– Maybe the quickest

Determine a Movement Route using a Map

• Find your Waypoints– What is a waypoint -A waypoint is a reference

point in physical space used for purposes of navigation.

– Use waypoints when you are changing direction or to verify your azimuth

Determine a Movement Route using a Map

• Determine Azimuth and Distance Between Waypoints

***If Traveling By Road Waypoints are only needed when changing Roads***
