korkeuskäyrien
Korkeuskäyrät, also known as contour lines, are lines on a map that connect points of equal elevation. They are a fundamental tool in cartography and geography for representing the three-dimensional topography of the Earth's surface on a two-dimensional map. The closer the contour lines are to each other, the steeper the slope of the land. Conversely, widely spaced contour lines indicate a gentler slope or relatively flat terrain.
Each contour line is labeled with its elevation, typically in meters or feet above sea level. The
Korkeuskäyrät are essential for various purposes, including navigation, land surveying, urban planning, and environmental studies. They
