Abstract
Evolutionary history of geographic objects (EHGO) in three-dimensional (3D) space at different levels of details (DLOD) 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 EHGO at DLOD over time, results of visual analysis are a model of representation of visualization of GO at DLOD over time, this model is called TLOD. Time is the class that records the time of formation and loss of GO. Time in this paper is divided into three main categories and integrate into the TLODs model, namely legal time (LT), event time (ET), and database time (DT). 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 TLOD 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.
