ArcGIS: Working With Geodatabase Topology. Topology—the spatial relationship between geographic features—is fundamental to ensuring data quality. Topology enables advanced spatial analysis and plays a fundamental role in ensuring the quality of a geographic information system (GIS) database.
Topology is the spatial relationship between connection and adjacent coverage features. Topological relationships are built from simple elements into complex elements: line, points, and areas. Topology is defined as the mathematical procedure for explicitly defining spatial relationships between the data (connectivity or adja-
Topology Rules. Define integrity rules and constraints for the feature classes. Can include point, line and polygon features. Evaluated when the topology is validated. Violations are expressed as topology errors. 31 different rule types. 14 ArcGIS Topology rules can emulate coverage model. More may follow.

This article deals with topological concepts and models which are necessary to represent three-dimensional urban objects in a geographical information system (GIS). Depending on the shape and the representation of features, several classes with increasing topological complexity are identified and described.
