karttalevyinen

Karttalevyinen is a Finnish term that translates to "map-disc" or "chart-disc" in English. It refers to a type of plate or disc that is used in various applications, often related to navigation, mapping, or mechanical systems where precise angular positioning is required. These discs typically have markings or divisions that correspond to specific angles or directions, similar to those found on a compass rose or a protractor.

Historically, karttalevyinen might have been used in nautical instruments for determining bearings or in early surveying equipment. In modern contexts, the term can appear in technical descriptions of machinery or tools. For instance, a karttalevyinen could be a component in a device that needs to rotate to a specific, predetermined position, with the disc acting as a visual or mechanical guide. The precision of the markings on the disc is crucial for its intended function, whether it's for accurate measurement or repeatable positioning. The material of a karttalevyinen can vary depending on its use, ranging from metal to durable plastics.
