MAP READING & LAND NAVIGATION
(TC 3-25.26)
What are the basic colors of a map, and what does each color represent?
Black — Indicates cultural (man—made) features such as buildings and roads,
surveyed spot elevations, and all labels.
Red—Brown — The colors red and brawn are combined to identify cultural
features, all relief features, non—surveyed spot elevations, and
elevation, such as contour lines on red— light readable maps.
Blue — Identifies hydrography or water features such as lakes, swamps, rivers, and
drainage.
Green — Identifies vegetation with military significance, such as woods, orchards,
and vineyards.
25 November 2016 Cadet Board Study Guide 18Brown — Identifies all relief features and elevation, such as contours an alder
edition maps, and cultivated Land on red—light readable maps.
Red — Classifies cultural features, such as populated areas, main roads, and
boundaries, on older naps.
Other — Occasionally other colors may be used to show special information. These
are indicated in the marginal information as a rule.
Where is the Legend of the map found? Lower
Left Margin
What are contour lines?
Imaginary lines on the ground connecting equal elevation, thy represent high and
low ground elevation
What are 3 types of contour lines?
1. Index
2. Intermediate
3. Supplementary
How many Mils are in one Degree?
17.7 mils
How many Norths are there on a military map?
Three
1. True north
2. Magnetic north
3. Grid north
What shapes are the contour lines that indicate a hill?
A hill is shown on a map by contour lines forming concentric circles. Inside the
smallest closed circle is the hilltop.
What shapes are the contour lines that indicate a saddle?
A saddle is normally represented as an hourglass
25 November 2016 Cadet Board Study Guide 19What shape are the contour lines that indicate a valley?
Contour lines forming a valley are either U—shaped or V—shaped.
What shape are the contour lines that indicate a ridge?
Contour lines forming a ridge tend to be U—shaped V—shaped. The closed end of
line points away from high ground.
What shape are the contour lines that indicate depression?
Usually Only depressions that are equal greater than the contour interval will be
shown. On maps, depressions are represented by closed contour lines that have Lick
marks painting toward low ground.
What shape are the contour lines that indicate a draw?
The contour lines depicting a draw are U—shaped or V—shaped, pointing toward
high ground.
25 November 2016 Cadet Board Study Guide 20What shape are the contour lines that indicate a Spur?
Contour lines on a map depict a spur with the U or V pointing away from high
ground.
What shape are the contour that indicate a cliff?
Cliffs are also shown by contour lines very close together and, in some instances,
touching each other.
What shape are the contour lines that indicate a cut?
This contour line extends the length of the cut and has tick marks that extend from
the cuts line to the roadbed, if the map scale permits this level of detail.
What shape are the contour lines that indicate a fill?
This contour line extends the length at the filled area and has tick marks that point
toward lower ground. If the map scale permits, the length of the fill tick marks are
drawn to scale and extend from the base line of the fill symbol.
25 November 2016 Cadet Board Study Guide 21What must be done to a map before it can be used?
It must be oriented.
What are 5 major terrain features found On a map?
1. Hill
2. Ridge
3. Valley
4. Saddle
5. Depression
What are the 3 minor terrain features found on a military map?
1. Draw
2. Spur
3. Cliff
What are the 2 supplementary terrain features found on a military map?
1. cut
2. Fill
What is a map?
a flat plane.

What is an azimuth?
A horizontal angle, measured in a clockwise manner from a north base line,
expressing direction.
What is vertical distance?
The distance between the highest and lowest points measured.
What is a contour interval?
The distance between contour lines.
What is the distance between grid lines on a military map?
25 November 2016 Cadet Board Study Guide 221 kilometer or 100 meters
How many mils ace there in a circle?
6400 mils in 360 degrees
Which north is used using a military map?
Magnetic north when using a compass, and grid north when using the map
How would you hold a lensaeic compass?
Away from metal (weapons, electrical devices), level and firm
Name two ways to hold a compass?
1. Compass-to-cheek Method
2. Center- Hold Method
Are topographic symbols drawn to scale? No
What do topographic symbols represent? Man—made
and natural objects
In Military symbols, what colors are used for a map overlay and what do they represent?
Blue— Friendly forces
Red-Enemy farces
Black— boundaries
Yellow—contaminated area bath friendly and enemy
Green— engineer obstacles, both friendly and enemy
What is Back Azimuth?
The reverse direction of an azimuth.
How do you figure out a back azimuth?
If an azimuth is 1180 degrees or less, you add 180 degrees to find out: the back
azimuth. If the azimuth is more than 180 degrees, you subtract 180 degrees to find
the back azimuth.
What is a declination diagram?
Shows the interrelationship between the magnetic north, grid north and true north
What is the general rule for reading military grid coordinates? Right
and Op
