polygon-arc topology
The topological data structure ArcInfo uses to represent connectivity between arcs to form polygons. Polygon-arc topology supports the definition of polygons and analysis functions such as topological overlay.
polygon-arc topology
In a polygon coverage, the list of topologically connected arcs that define the boundary of a polygon feature and the label point that links it to an attribute record in the coverage point attribute table.

[data analysis] In a coverage, the topological identification of adjacent polygons by recording the left and right polygon for each arc.
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.
