ABSTRACT: Increasing of population very fast makes the urban architecture more and more become overload, which will lead to increase the positive and the negative sides in the residential community. Urban management stage is becoming increasingly urgent. We need to manage many aspects and especially to be timely at all times. Each of objects is a close relationship with one another making multiple levels of detail and users can observe at different angles. This paper focuses on researching and developing visual representation model of geographic objects (people (Ps), buildings (Bs) and geospatial space (GSs)) along with the relationships (blood relationships (BRs), social relationships (SRs), previous conviction relationships (PCRs), previous offence relationships (PORs), and vital relationships (VRs)) in 3D space (GS3D) at levels of different details (DLOD), which serves the protection of security and order of the social and safety in the area, it was called VRO-DLOD3D data model. This new model was installed on database management system of Oracle, used type of spatial data of Oracle and combined with the C# programming language to present data in the forms via some typical queries and finalized experimental results showing that it can be applied to the population data management system.
