vägstråk

Vägstråk, also known as road centerlines or road axes, are the central lines that represent the path of a road on a map or in a geographic information system (GIS). They are used to define the location and alignment of roads, and are essential for various applications such as navigation, route planning, and traffic management. Vägstråk can be derived from various sources, including satellite imagery, aerial photography, and field surveys. They are typically represented as linear features in GIS, with attributes such as road name, type, and width. Vägstråk are used in a wide range of applications, including urban planning, transportation engineering, and environmental management. They are also used in the development of digital maps and navigation systems, where they provide the underlying data for route calculation and display. In summary, vägstråk are a fundamental component of modern transportation and mapping systems, providing a standardized and accurate representation of road networks.
