Kontuuriväliin

Kontuuriväliin refers to a Finnish term describing the spacing or interval between contours. Contours, in cartography and surveying, are lines that connect points of equal elevation or value on a map. The kontuuriväliin, therefore, indicates the vertical distance represented by each contour line. This value is crucial for understanding the steepness and shape of the terrain.

A smaller kontuuriväliin signifies a more detailed representation of the landscape, where contour lines are closer together. This suggests a steeper slope or rapid change in elevation. Conversely, a larger kontuuriväliin means fewer contour lines are used to depict the same area, and they are spaced further apart. This implies a gentler slope or more gradual elevation changes.

The specific kontuuriväliin used on a map is determined by the scale of the map and the purpose for which it is intended. For topographic maps used in hiking or mountaineering, a smaller interval might be preferred for detailed terrain analysis. For more generalized regional maps, a larger interval might be sufficient. The kontuuriväliin is typically indicated in the map legend, allowing users to accurately interpret the elevation data presented. Understanding the kontuuriväliin is fundamental to correctly reading and utilizing topographic maps.
