terrengkurven

Terrengkurven, often translated as contour lines or contour curves, are lines drawn on maps that connect points of equal elevation. These lines are fundamental to understanding the topography or relief of an area. Each contour line represents a specific height above a reference level, usually sea level. The interval between consecutive contour lines, known as the contour interval, is consistent across a map and indicates the difference in elevation between adjacent lines.

The spacing of contour lines provides crucial information about the steepness of the terrain. Closely spaced lines indicate a steep slope, as the elevation changes rapidly over a short horizontal distance. Conversely, widely spaced lines suggest a gentle slope or relatively flat terrain. Contour lines never cross or merge, except in the rare case of an overhang or cliff, where they might appear to coincide. Closed contour lines, especially those with decreasing elevation inwards, typically represent hills or mountains, while those with increasing elevation inwards can denote depressions or basins.

Terrengkurven are essential tools for various disciplines, including geography, geology, surveying, hiking, and urban planning. They allow map users to visualize the shape of the land, identify features such as valleys, ridges, and peaks, and plan routes that consider elevation changes. Understanding how to read and interpret terrengkurven is a key skill for anyone working with or relying on topographic maps.
