Describe the integrity constraints of integrated topological models (e.g., POLYVRT)
Discuss the historical roots of the Census Bureau’s creation of GBF/DIME as the foundation for the development of topological data structures
Explain why integrated topological models have lost favor in commercial GIS software
Evaluate the positive and negative impacts of the shift from integrated topological models
Discuss the role of graph theory in topological structures
