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.

Level Curves and Contour Plots. Level curves and contour plots are another way of visualizing functions of two variables. If you have seen a topographic map then you have seen a contour plot. Example: To illustrate this we first draw the graph of z = x2 + y2. On this graph we draw contours, which are curves at a fixed height z = constant.
essence, a \topographical map" of the graph of z = f(x;y). A topographical map is a two-dimensional visualization of three-dimensional terrain through the so-called level curves or contours corresponding to points of equal elevation. Example 1. Here is a map of the region near South Hamilton, NY:
Level curves are the equivalent of contours on a topographical map. In such a map the terrain is shown by drawing curves through all points which have the same height above sea level. The numbers on the curves in the map shown below are the heights above sea level in metres. 🔗. Figure 3.2.1. Sample Topographic Map (Part of the Watagan Mountains)

How do you calculate relief on a topographic map?
The span of the third dimension (elevation) represented by contour lines on a topographic map is called the relief. The relief for a topographic map is easily calculated by finding the highest and lowest contour line elevations on the map; you then subtract the two values to determine the vertical relief represented in the map.
