To assure that this is the case, all feature classes that take part in a geodatabase topology must reside within what is known as a Feature Dataset.

Therefore, it is not only important that all of the feature classes participating in a geodatabase topology be in the same coordinate system, but also that the measurement precision defined for each feature class be the same. It does so by analyzing coordinate locations of feature vertices both among features within a feature class and between features in multiple feature classes taking part in the topology. A geodatabase topology is another construct that is stored within a geodatabase and gives us added control over assessing and maintaining the integrity of our spatial data.įollow this link to download the data for this part of the lesson: Topology_ArcMap.zipĪn Esri Personal Geodatabase: geodatabasetopol.mdbĪ zip archive: TopologyProject.zip Controlling spatial data integrity by imposing rules - Geodatabase TopologyĪ geodatabase topology provides a robust way of defining topological relationships among spatial features.
