Korkeustietoja

Korkeustietoja, which translates to "altitude data" or "height information" in English, refers to the geographical or vertical position of a point relative to a reference level. This reference level is typically mean sea level, but can also be a local datum or a geoid model. Korkeustietoja is crucial in various fields including surveying, cartography, engineering, and aviation.

In surveying and mapping, korkeustietoja is determined through precise measurements using instruments like levels, total stations, and GPS receivers. These measurements are used to create topographic maps, which depict the shape and elevation of the land. Engineers rely on korkeustietoja for the design and construction of infrastructure projects such as roads, bridges, and buildings, ensuring proper drainage and structural stability.

For aviation, accurate korkeustietoja is vital for flight planning, air traffic control, and maintaining safe separation between aircraft. Pilots need to know their altitude relative to the ground and other airborne objects. Meteorological applications also utilize altitude data to understand atmospheric conditions and weather patterns. The concept of korkeustietoja encompasses both absolute altitude, measured from sea level, and relative altitude, measured from a local ground feature.
