Topology is the study of geometrical properties and spatial relations that are unaffected by continuous changes in the shape and size of a figure. A topologist doesn’t see any difference between a donut and a coffee cup. In ArcGIS, topology in a geodatabase is the arrangement that defines how point, line and polygon features share…
