Evolutionary history of geographic objects (EHGOS) in three-dimensional (3D) space at different levels of details (DLODS) over time is due to natural law or imposed by humans and always goes on every day. To represent visualization this evolutionary history, this paper proposes visual analysis of EHGOS at DLODS over time, results of visual analysis are a model of representation of visualization of GOS at DLODS over time, this model is called TLODS. Time is the class that records the time of formation and loss of GOS. Time in this paper is divided into three main categories and integrate into the TLODs model, namely legal time (LTS), event time (ETS), and database time (DTS). When manipulating queries can be either point of time or period of time in three types of time. This paper presents the experimental setup of the TLODS model in Oracle 11G and incorporating in C# to represent typical forms. Experimental results show that it can be applied to the management of urban technical infrastructure in practice.
