2025年1月23日 · The meaning of CONTOUR LINE is a line (as on a map) connecting the points on a land surface that have the same elevation.

Contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level. Imagine a land surface inundated by the sea to a depth of 100 feet (30.5 …

Contour lines are curved, straight or a mixture of both lines on a map describing the intersection of a real or hypothetical surface with one or more horizontal planes. The configuration of these contours allows map readers to infer the relative gradient of a parameter and estimate that parameter at specific places.

2022年2月5日 · Other than the obvious trails and rivers, these squiggly lines are contour lines. Put simply, contour lines mark points of equal elevation on a map. If you trace the length of a line with your finger, each point you touch is the same height above sea level.

The Basics of Contour Lines. Definition of Contour Lines. In the simplest terms, contour lines are lines on a map that connect points of equal elevation. Imagine you’re on a mountain, and you walk around it at the same height without going up or down. The path you create would be a …

2021年8月10日 · Contour lines are continuous lines that connect points of equal elevation on a map. They are created by connecting points of equal elevation, which means that they will never cross each other. They can come near to each other at some point but never crosses each other.

For a quick definition, a contour line joins points of equal and constant values. For example, contours on an elevation have constant heights that are the same on each line in a topographic map.

A contour line is a line on a map that connects points of equal elevation above a specific level, usually sea level. These lines are crucial for understanding the topography of an area, as they indicate the shape and steepness of the terrain.

By definition, contour lines separate points of higher elevation from points of lower elevation. This means it is always possible to define an “uphill” direction on one side of a contour and a “downhill” direction on the other side.

A line on a map joining points of equal elevation above a given level, usually mean sea level. The change in elevation between one contour line and the next is the contour interval. Discover More
