Many maps have either a 40- or 80-foot contour interval: An 80-foot interval simply means that each contour line is 80 vertical feet away from the next closest line. You find the contour interval for your map in its legend. Every once in a while, a circle indicates a depression rather than a peak.

Contour maps are a way to depict functions with a two-dimensional input and a one-dimensional output. For example, consider this function: . With graphs, the way to associate the input with the output is to combine both into a triplet , and plot that triplet as a point in three-dimensional space. Explain to students that a contour map is another name for a topographic map, or a map that shows the elevation of land on a flat paper surface. Ask: Why might this be useful? Elicit from students that contour maps are a convenient way to visualize flat and steep terrain, especially for hikers or other people navigating with maps. Contour maps show the elevations of these surface features, which allows you to look at a 2-dimensional map to visualize the Earth in three dimensions.

Contour maps offer a deceptively high amount of information when analyzed skillfully, and can be accessed on command using online mapping sites and applications. Contour lines are spaced by contour intervals and represent areas on land that lie the same distance above sea level, taken to be zero feet (0') by convention. A contour is an imaginary line on the ground joining the point having equal elevation or a line joining the points of the same elevation is known as a contour line.. A map or plan representing a three-dimensional picture of the ground with the help of the contour line is called a contour map or plan. 2019-04-04 · Contour lines that form a series of circles on the map, where the circles get smaller and smaller, indicate a raised land mass.

Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. Intermediate lines are the thinner, more common, lines between the index lines. A base contour is used, for example, when you want to create contours every 15 meters, starting at 10 meters.

Overall contour accuracy depends on how well the data used to create the input raster represents the actual surface. 2018-11-04 The small contour interval, the survey work and plotting have to be more accurate. For small contour interval, the money required will also more as the field and office work will be more. Consideration in making the choice of the proper contour interval. Before preparing a contour map, the contour interval required is decided.
