Use a different symbol or color for the data points from “Point A” to the rim and from “Point B” to the rim. Label the x axis with total distance (km) (Column C) Label the y axis with elevation (m) (Column A) Connect the data points for each set of data. Write a key for the graph.

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.
topographic-skills.pdf (Page 2 of 2) Look at the extract from a simple topographic map featured on the first page of this worksheet. Use it to answer the questions below. 1. How much higher is the land at point D than at point F? How do you know?..... 2. How do you know that Mt Erin is more than 350 m above sea level?
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.

How are topographic maps able to show three-dimensional objects like hills on a two-dimensional object like a piece of paper? They do it by using contour lines. Contour Lines are curves that connect points of equal elevation. Each contour line on a map has a number that represents the elevation of the line (usually the height above sea level).

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.

However you will need to use vertical exaggeration to show the topography of the area effectively on your cross section. The bottom of the section is at 400 m above sea level. Use a vertical scale of 10 m = 2 mm and a horizontal scale that is the same as the map.
