More Meanings Of Contour

Here the route forks left to contour across the hillside back to the ski village. One option is to contour the underside of the lake, making it deep in the center and shallow on the edges.

This technique was utilized in 1791 by J.L Dupain-Treil for a map of France and in 1801 Haxo used it for his tasks in Rocca d’Aufo. Since then there has been a widespread use of contour strains for mapping and other functions. The use of lines joining points of equal worth has been existent since a long time though they have been recognized by names other than contour traces. Contour lines denoting fixed depth are now often known as “isobaths”. Throughout the 1700s contour traces have been utilized in quite a few charts and maps for instance depths and heights of water bodies and landscapes.

Typically one index line occurs for every 5 intermediate strains. F. Saddle.A saddle is a low mendacity space between two higher factors of elevation.

If the traces are spaced far aside then it represents a mild slope. Streams and rivers in a valley are represented by a “v” or a “u” in a contour map. If each line represents an equal point of elevation, then any change in elevation would lead to inconsistent line spacing, proper? For instance, several contour strains spaced close collectively would indicate steep terrain, whereas traces spaced far aside would point out a gentler slope. Edmond Halley in 1701 used contour strains on a chart of magnetic variation.

Topographic Maps

While representing a terrain, shut contours symbolize a steep slope or gradient while distant contours characterize a shallow slope. The closed loops on the inside characterize uphill whereas the surface reveals downhill. The isogon or isogonic contour traces represents the road of constant magnetic declination. The contour line that joins the factors of zero magnetic declination is called as Agonic line. A contour line that joins all the points with fixed magnetic pressure is known as as isodynamic line.
