Topographic Maps

Front

Topographic/Contour Map

Back

-A map that shows the shape of the land using contour lines

-A map that shows an elevation field, meaning how high and low the ground is in relation to sea level

Front

Elevation Field

Back

-How high and low the ground is in relation to sea level

Front

-Planning for hiking, camping, hunting, etc.

-Finding the simplest and safest route

-Finding where high and low elevations exist in an area

-Evacuation routes in emergencies

-Where rivers, streams, and swamps are located

Back

What do we need a topographic map for?

Front

Contour Lines

Back

-Lines that show areas of equal elevation

-They never cross

Front

Steep Slope

Back

-When the contour lines are close together and it has a steep slope

-Represents a hill/cliff

Front

Gentle Slope

Back

When the contour lines are spaced apart

Front

Hachture

Back

-Small tic marks on the inside of a circle

-Shows negative elevation (ditch/depression)

Front

Hill/Mountain

Back

Circular lines on a topographic/contour map

Front

Contour Interval

Back

-Tells you the change in elevation from one contour line to the next

-Darker lines are for reference

Front

-It always flows from a high elevation to a low elevation

-Look where the stream passes through the contour lines. The lines form a "V" shape and the stream flows towards the open end of the "V"

Back

How can you tell which way a stream or a river flows?
