valuable details to help you understand and use a topographic map. For example, here you will find the map scale and other important information about the map such as the year, the edition and information pertaining to the map data.

Topographic mapping skills. A topographic map shows the varying shapes, heights and slopes of a landscape using contour lines .That’s why they are so useful for bushwalking, property mapping and even town planning. Contours are lines that connect points at the same height above sea level and are plotted using vertical aerial photographs.
Part 1: Develop your topographic map reading skills by working with simplified diagrams that illustrate key elements of topographic maps. Part 2: Practice your map reading skills by interpreting snippets from topographic maps. Part 3: Apply your skills to interpret an actual topographic map of a full quadrangle. 1.

along a path that is level, and end at the same point from which you started. A level curve projected onto the xy-plane is called a contour. A surface representing = ( , ) is shown at left, then intersected by a plane =𝑘. The bold path is “level” in that the z-values on it do not change.
[A saddle point is a level spot from which you can go down in some direction and up in some other direction.] Give approximate xy-coordinates for each of these three features. Write down the equations of level curves for f(x,y) = x 2 + y 2 for four values of c. Plot this surface and these level curves in your worksheet.
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.
