By interpreting the Contour map the consumer is able to infer the relative gradient of the floor. Be it the depth or the height of a panorama, a contour map can help to represent the topography of the realm. The house between two strains and the spacing along the traces offers consumer with necessary info.
Some Options Which Are Incessantly Used In Mapping:
While representing a terrain, close contours represent a steep slope or gradient whereas distant contours symbolize a shallow slope. The closed loops on the within characterize uphill whereas the surface shows downhill. The isogon or isogonic contour strains represents the road of fixed magnetic declination. The contour line that joins the points of zero magnetic declination known as as Agonic line. A contour line that joins all the factors with constant magnetic pressure known as as isodynamic line.
