    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.

    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).

    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.

    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.

    Aug 18, 2022 · Topographic Contours. 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. A contour is a horizontal curve that’s the locus of all points on the map with the same elevation (Figure 3-35).

    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. For example the curve at height z = 1 is the circle x2 + y2 = 1.
