Topographic Map Notes
What is topography?
The mapping of elevation/height.
What does a topographic map tell you, that other maps can't?
Topographic maps tells us the elevation.
Who might use a topographic map (and why?)
Geologists, Geographers, Marine Scientists and Farmers use topography maps to map the ocean and the land. Pilots and Firefighters use them for direction and direction of heat.
Define the following:
Elevation:
Height of a place relative to a reference height (Usually Sea level or Average Ground Level).
Contour Lines:
A line connecting points that have the same elevation.
Contour Interval:
The difference in elevation between two adjacent contour lines.
Depression Contour:
Contour lines that indicate a downward slope. It is drawn with hatch marks.
Practice Questions:
1) Which of the topographic maps shows two peaks? Map C
Which side has higher elevation? The left side.
2) Which topographic map shows the steepest cliff? Map B
Where is it?
It is the map on the top-right, because the contour lines are the closest together.
3) Can you tell the elevation of the topographic feature in plot B exactly? If so, what is the elevation, if not, why and what would be your closest guess?
No, It isn't clearly labeled.
4) Which topographic map has a contour interval of fifty (50) feet? Map A
5) Which of the topographic maps depicts a canyon, or depression? Map B
