What type of map shows heights?
Topographic maps are 2-dimensional representations of the 3-dimensional surface features of an area. Topographic maps have contour lines that connect points of identical elevation above sea level.
What is elevation on a map?
Elevation is distance above sea level. They can be shown on maps by contour lines, which connect points with the same elevation; by bands of color; or by numbers giving the exact elevations of particular points on the Earths surface. Maps that show elevations are called topographic maps.
