Abstract: Topology is fundamentally used to ensure data quality and aid in data compilation. Most users care deeply about the integrity of their spatial feature dataset, while others are more concerned with optimum performance of analytical operations. Topology aids in analyzing spatial relationships in many situations such as dissolving the boundaries between adjacent polygons with the same attribute values or traversing along a network of the elements in a topology graph. This paper seeks to model how the geometry from a number of feature classes can be integrated and these is referring to as vertical integration of feature classes and also carry out topological operations on satellite imagery of University of Lagos depicted as points, lines and polygons. Spatial integrity of feature datasets was checked and analytical operations such as queries were performed.
Keywords: dataset, topology, spatial integrity, geo-referencing, geo-database, integration.
