Node
A point at which two or more lines (arcs) connect in a spatial network, fundamental for network analysis such as transportation or utility modelling.
How do we describe a Node?
A node is a crucial component used in the modelling of spatial networks in geographic information systems (GIS). In a network, it designates a particular location where lines or edges converge to form junctions, endpoints, or intersections. For instance, nodes can identify points like transformers, valves, or water junctions in utility networks, or they can represent locations like street intersections, bus stops, or train stations in transportation networks. Establishing connectivity and facilitating network-based analysis, including shortest path computation, depends on the nodes. Analysis of service areas and flow modelling. In addition to the usual geographic coordinates, each node may also have other attribute data, such as capacity, signal type, or elevation. Together, nodes and edges form an organized and navigable network model that mimics actual infrastructure and facilitates intricate spatial decision-making.
