topographic map

A map that shows the contours of the land via a two-dimensional drawing with multitudes of contour lines showing changes in elevations.Each map has its own scale.The contour lines indicate a change in elevation by the scale amount. For example, each line might represent a 1-foot change in elevation. The distance between the lines can be computed by reference to the distance scale.For example,1 inch might equal 50 feet.Two contour lines that are 1 inch apart would indicate a grade of 1 foot over the course of 50 feet, which is very gentle. The closer the lines on the topographic map, the steeper the incline.
