Korkeuseroa is a Finnish geographic term that denotes the vertical difference in elevation between two points on the Earth's surface. It is commonly used in cartography, surveying, and landscape analysis to describe how high one point is relative to another.
Measuring korkeuseroa involves determining elevations and calculating their difference. Elevations can be obtained from topographic maps,
Applications include hydrology (watershed delineation and flood risk assessment), geology (relief and slope assessment), civil engineering
