DQ: How do we define features on a contour map?

• Anchor: Answer question based on this map.

How do we analyze a contour map?

Contour Lines Rules

• 1) All points along any given contour line represent the same elevation

• 2) Contour lines never touch or cross • 3) The spacing between contour lines help us determine the

slope. • 4) When contour lines cross a stream or a river they are V

shaped.

19) Index Contour: A darkened contour line used to represent a specific elevation. It help us determine elevation at certain points more quickly. Index contour are evenly spaced for example: every 100 feet or every 200 feet.

How can we predict the contour interval?

How do we add directions to contour map?

How can we read special features on a contour map?
