Abstract	The GIS applications require the attributes of semantic, space and time data. Spatial data describe the shape, size, location. Temporal data record the time of creation, loss of the space object and history of the changes are stored in the database. The modeling stage is very important first step to build a database of space-time in a GIS application. There have been many models of the authors have proposed in the past, the paper presents a summary of this model. This paper proposes a new 4D space-time data model, it was called TUDM. Time dimension in TUDM integrated into a known 3D GIS space model. TUDM is the pure model temporal-spatial. Time dimension in the model may be either instant or interval time. Born, died time of an object in the model can be happened time in the real world or database. The new model can be represent and store not only explicit evolution history of objects 0D, 1D, 2D but also object 3D in their lifecycle. The TUDM is designed to integrate easy to semantic object when merging to the specified application. The paper compares it to other models. Final part is the experiments with queries on sample data.
