A topographical map contains curved lines called contour lines. Each contour line corresponds to the points on the map that have equal elevation (Figure 1). A level curve of a function of two variables [latex]f\,(x,\ y)[/latex] is completely analogous to a counter line on a topographical map.

How do you know?..... 2. How do you know that Mt Erin is more than 350 m above sea level?..... 3. (a) If you walked from the railway station to Mt Erin ...
One special kind of map is called a topographic map. It has contour lines to show the shape and elevation of the land. They are sometimes called "level lines" because they show points that are at the same level. Here's how contour lines work: The top of this drawing is a con-tour map showing the hills that are illustrated at the bottom.

A contour line (also known as a level curve) for a given surface is the curve of intersection of the surface with a horizontal plane, z = c. A representative collection of contour lines, projected onto the xy -plane, is a contour map or contour plot of the surface.
