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.

A contour diagram is, in 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.
The latitude and longitude coordinates of NRCan maps are found along the edge of a map (for example see the map of Canadian geology we studied in Chapter 1). On USGS topographic maps the latitude and longitude coordinates are found at the corners of the map (Figure 7.2).

3.3 Level Curves and Level Surfaces. Topographic (also called contour) maps are an effective way to show the elevation in 2-D maps. These maps are marked with contour lines or curves connecting points of equal height. Figure 1: Topographic map of Stowe, Vermont, in the US.
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.

The scale of map you work with depends on the level of detail you want to show on the map. 5. TOPOGRAPHIC CONTOURS 5.1 Many maps of land areas have series of curved lines, called contours, that represent the topography of the area. Such a map is called a topographic map.Acontour is a horizontal curve that’s the locus of all
