What is another name for an edge in GIS?

In Geographic Information Systems (GIS), an edge is commonly referred to as a line. Edges are the connections between nodes in spatial data models, particularly in network analysis or geometric representations. They represent linear features in a spatial context, such as roads, rivers, or boundaries.

When considering the other terms: a point refers to a specific coordinate in space without any length or width, making it distinct from an edge. A node is typically used to represent a point where two or more edges meet but does not serve as a synonym for an edge itself. A polygon is a closed geometric figure formed by connecting a series of edges or lines, representing areas rather than individual linear connections. Therefore, the most appropriate term that corresponds to the definition of an edge in this context is line.
