Creating geodatabase topology

In a map, topology refers to spatial relationships between features, such as:

• Connectivity: This indicates that rivers from the WatercourseL feature class or roads from the RoadL feature class should be connected
• Coincidence: This indicates that the water and roads from the Watercourse and Road polygon feature classes should be covered by the Hydrography and Transportation subtypes from the LandUse feature class
• Adjacency: This indicates that parcels from LandUse have common edges and should not overlap or have gaps
• Containment: This indicates that buildings from the Buildings feature class should be within the Other Terrain (Built-up area) subtype from the LandUse feature class

In the ArcGIS context, a topology is a collection of rules that define the spatial relationship between features within a feature class or between features of two or more feature classes belonging to the same feature dataset.

A topology is stored in a file geodatabase as an individual File...
