Arc-node Topology

arc-node topologyThe topological data structure ARC/INFO uses to represent connectivity between arcs and nodes.

 


arc-node topology
The data structure in a coverage used to represent linear features and polygon boundaries and to support analysis functions, such as network tracing. Nodes represent the beginning and ending vertices of each arc.

The arc-node topology data model is central to many ArcGIS vector operations. Arcs are represented with starting and ending nodes, which imparts directionality to the arcs.

See Also: arc-node topology, polygon-arc topology
[ESRI software] In geodatabases, the arrangement that constrains how point, line, and polygon features share geometry.

Arcs are topologically linked to nodes (arc-node topology) and to polygons (polygon-arc topology). The descriptive attributes of arcs are stored in the arc attribute table (AAT). See also node.
