Arc
A line segment defined by its endpoints (nodes), fundamental in vector data models for representing linear features.
How is an Arc defined?
An arc is defined as a curved line or a portion of a circle that connects two points. In geometry, it represents a segment of a circle's circumference. In Geographic Information Systems (GIS) and digital mapping, an arc typically refers to a line feature that may be curved or straight, used to represent linear geographic elements such as roads, rivers, or boundaries.
In GIS, arcs are made up of a series of points or vertices and can carry attributes (like road names or lengths). They are fundamental components of vector data models, especially in topological data structures, where arcs help define the shapes and relationships between spatial features like polygons and networks.
