Välimatkat

Välimatkat is the Finnish term for distances—the lengths or extents between two points. The concept is used across many disciplines, including geography, mathematics, physics, and everyday navigation. In Finnish, välimatka refers to a separation in space, and välimatkat is the plural form. The term is common in maps, travel planning, and scientific discussions about location and movement.

Two common ways to measure välimatkat are the straight-line distance and the path distance. Straight-line distance, or geodesic distance on the Earth’s surface, is the shortest possible separation between points. Path distance relates to the route taken along roads, rails, or waterways and is typically longer due to curves and constraints. Distances on a spherical Earth are often approximated by great-circle calculations.

Units and instruments: Distances are expressed in meters and kilometers in most contexts; in aviation and maritime settings nautical miles may be used. In astronomy, larger units such as astronomical units, light-years, and parsecs apply. Distances can be measured directly with rulers or rangefinders, or inferred via GPS, map data, or GIS analyses. Map projections and the curvature of the Earth can influence measured distances in cartography.

Applications: Välimatkat are fundamental in urban planning, transportation, logistics, sports, and education. They underpin route optimization, distance-based pricing, and the design of networks. The concept also raises methodological considerations, such as choosing an appropriate distance metric in analysis or accounting for projection distortion in maps.
