5. Topographic Map
Shows the three dimensional shape and elevations of an area of land in two dimensions
Sample taken from the public domain USGS Digital Raster Graphic file o44072d6.tif for the Stowe, VT quadrangle

6. Elevation
Height above sea level

7. Label the contour lines on your map.
Line that connects places on a topographic map that are all at the same elevation (eventually a closed loop)
Label the contour lines on your map.
contour line

8. Label the contour line interval on your map.
The vertical difference in elevation between neighboring contour lines
Label the contour line interval on your map.

9. Relief
The difference between the highest elevation point and the lowest elevation point on a map
200
300
400
Units = meters
What is the relief of this map?
What is the contour interval of this map?

10. Topographic Map Rules Contour lines are closely spaced on
steep slopes.
Contour lines are widely spaced on
gentle slopes.

11. Topographic Map Rules
The top of a hill or mountain forms a closed area. The top of the hill has a higher elevation than the previous contour line, but it has a lower elevation than the next contour line.
In the map above, the contour interval is 50m so the max elevation is between 400 and 450

12. Topographic Map Rules
Rivers and valleys are lower elevation areas. These lower elevation areas change the contour lines. The changes in the contour lines area shown as a “V” shape. The angle in the “V” points to the area upstream. The river and/or valley can be followed through the topographic map by following the “V” shapes.

13. Topographic Map Rules
Depressions without outlets are shown by closed hatched contour lines. The hatched contour lines have short lines on the inside that are pointing down slope. The bottom of the depression is lower than the lowest closed contour line.
