Front 1

What are the basic colors of a map, and what does each color represent?

Back 1

Black - Indicates cultural (man-made) features such as buildings and roads, surveyed spot elevations, and all labels.
Red-Brown - The colors red and brown 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.
Brown - Identifies all relief features and elevation, such as contours on older edition maps, and cultivated land on red-light readable maps.
Red - Classifies cultural features, such as populated areas, main roads, and boundaries, on older maps.
Other - Occasionally other colors may be used to show special information. These are indicated in the marginal information as a rule.

Front 8

What shape are the contour lines that indicate a hill?

Back 8

A hill is shown on a map by contour lines forming concentric circles. The inside of the smallest closed circle is the hilltop.

Front 9

What shape are the contour lines that indicate a saddle?

Back 9

A saddle is normally represented as an hourglass

Front 10

What shape are the contour lines that indicate a valley?

Back 10

Contour lines forming a valley are either U-shaped or V-shaped.

Front 11

What shape are the contour lines that indicate a Ridge?

Back 11

Contour lines forming a ridge tend to be U-shaped or V-shaped. The closed end of the contour line points away from high ground.

Front 12

What shape are the contour lines that indicate a depression?

Back 12

Usually only depressions that are equal to or greater than the contour interval will be shown. On maps, depressions are represented by closed contour lines that have tick marks pointing toward low ground.

Front 13

What shape are the contour lines that indicate a draw?

Back 13

The contour lines depicting a draw are U-shaped or V-shaped, pointing toward high ground.

Front 14

What shape are the contour lines that indicate a spur?

Back 14

Contour lines on a map depict a spur with the U or V pointing away from high ground.

Front 15

What shape are the contour lines that indicate a cliff?

Back 15

Cliffs are also shown by contour lines very close together and, in some instances, touching each other.

Front 16

What shape are the contour lines that indicate a cut?

Back 16

This contour line extends the length of the cut and has tick marks that extend from the cut line to the roadbed, if the map scale permits this level of detail.

Front 17

What shape are the contour lines that indicate a fill?

Back 17

This contour line extends the length of 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.

Front 18

What must be done to a map before it can be used?
