Topographic maps

nA topographic map, also known as a contour map, is a map that shows the shape of the land using contour line.
nIt is a map that shows an elevation field, meaning how high and low the ground is in relation to sea level.

 

nContour lines are lines that connect points that are of the same elevation.
nnContour lines never touch or cross.



They show the exact elevation, the shape of the land, and the steepness of the land’s slope.



 

nContour lines form V’s that point upstream when they cross a stream. 
nIt is important to remember that they point in the opposite direction as the flow of water.


Here is a simulation of a topographic map from different angles
