Urban data model (UDM) is a three-dimensional (3D) geography information systems (GIS) data model. The paper proposes the time class into UDM to manage historical of changes on the spatial properties of Point (0D), Line (1D), Surface (2D) and Body (3D) object. The changes would store explicit in database. The LOD (levels of detail) class of 3D objects adds also to show buildings at four levels from simple to complex. Event class in the model should record the reasons to create changes on the 3D objects in their evolution. The last model named
