Contour Line Tracing Algorithm for Digital Topographic ...
These contour lines are also used for generating Digital Elevation Model (DEM) for 3D surface generation from any satellite imagery or aerial photographs. This paper suggests an algorithm that can be used for tracing contour lines automatically from contour maps extracted from the topographical sheets and creating a database....
Contour Line Tracing Algorithm for Digital Topographic Maps
Contour line is the main linear feature on topographic maps. Extraction of contour lines is tedious and time-consuming process, and is still an interesting problem.

27 Ideas for Teaching with Topographic Maps
Materials Required: Topographic maps, globe. Illustrate how lines of longitude converge from the equator to the poles. Illustrate the concept first on a globe. Next, show topographic maps from the northern part of the United States (North Dakota, for example) versus maps from the southern part of the country (Texas or Hawaii, for example).
Contour line - Wikipedia
A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f(x, y) parallel to the (x, y)-plane.In cartography, a contour line (often just called a "contour") joins points of equal elevation ......
