Topological ModelTopological relationships will not be affected by continuous distortions42
Topological ModelNodes, Arcs, and PolygonsTopological data structures are often based on nodes, arcs, and polygons‣Arc: a series of points that starts and end at a node.‣Node: intersection point where two or more arcs meet.‣Polygon: comprised of a closed chain of arcs that represent the boundries ofthe area.43
