The article concerns the application of data, collected by mobile devices, in models road maps needed in virtual environments. Recently, a system has been developed at UTH Radom, with the aim of tracking wanted vehicles. The simulation of such vehicles, understood as units with driver or passenger(s), the acquisition and transfer of related data as well as the processing of information obtained from observation cameras, are subject of ongoing research. A key component for an effective analysis of trajectories, are detailed digital road maps. Given the lack of access to commercial geo-information systems, the compilation of customized digital maps for the territory of interest, using open data collections of geographical data, is essential for research in the public sector. In the present paper, the adaptation of chosen Openstreetmap data structures to the described purposes is presented.
