Kompassisuunnan

Kompassisuunnan refers to the direction indicated by a compass. A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions (or points). The primary directions are North, South, East, and West. A compass typically has a magnetized needle that aligns itself with the Earth's magnetic field, pointing towards magnetic north.

The Earth's magnetic poles are not perfectly aligned with its geographic poles, meaning magnetic north and true north (geographic north) are slightly different. The difference between these two is called magnetic declination. Navigators must account for magnetic declination to determine true direction. This declination varies depending on the location on Earth and changes over time.

There are various types of compasses, including magnetic compasses, gyrocompasses, and GPS devices that can display directional information. Magnetic compasses are the most common for basic orientation. Understanding kompassisuunnan is fundamental for activities like hiking, sailing, aviation, and surveying, where accurate directional knowledge is crucial for reaching a destination safely and efficiently. Without a proper understanding of compass readings and potential adjustments for declination, errors in navigation can occur, leading to getting lost or deviating from the intended course.
