Representing topological relationships for spatiotemporal objects

Erlend Tøssebro, Mads Nygård
2010 Geoinformatica  
Some work has also been done to represent topology for 3D objects, and such representations could be used to store topology for spatiotemporal objects.  ...  Both a basic time slice model and a 3D model are examined to determine how suitable they are for storing topological relationships.  ...  The main problem with a 3D model is that although a spatiotemporal object can be represented as a 3D object, the topological relationships that one wants to query are often different in the spatial and  ...
