Spatial management at present has the opportunities to obtain support by information in the unusual scale. One of the ways is to use the tools of urban spatial information systems and possibility of linking the reference data with new sources of information emerging in the development of e-administration, and among them registers of facilities, the services they provide, and their customers. As the examples of establishing such a link, and of the variety of analysis made available consequently, two cases of processing data from thematic databases based on Wrocław urban spatial information system are presented. In the first case registers of inhabitants accommodation and migration are used. Geocoding this data as well as examining the spatial relationships with other characteristics of the place (e.g. distance from the city center, type of housing), provided new information on the demographic and spatial structure of population, trends and dynamics of migration processes within the city and beyond its borders. The information received provides the characteristics of individual sites, as well as allows for specification the quantitative parameters, constitute a basis for predictions. Analysis and demographic projections are of interest to most departments of the municipal authority, as the basis for determining the need for public services (health, social care, education) as well as the demand for utilities (water, heat, gas, internet). The second example concerns the use of electronic system of recruitment in schools via the Internet, which provided a comprehensive basis for planning the modernization of Wrocław schools network. Geocoding of objects was the starting point for a series of visual and quantitative analysis, including, among others: different image of the deployment of objects and their spatial relationships, the flow rate and intensity of these phenomena, the study of diversification of service indicators (spatial accessibility, distribution of commuting distances to the schools of different levels, the number of schools' attendants). In this way, characteristics of both schools and of zones of different type of residential area and socio-economic inhabitants profile were build. Juxtaposition of data has allowed also to investigate the compliance of school districts ranges with areas of the allocation found with assistance of GIS tools and with the real spatial distribution of living places of each school's students. The analysis provided the rationale for both planning a network of schools and the arguments for specific decisions concerning the maintenance or elimination of individual schools. It allows also to identify under-served areas and to plan the routes of school-bus. Although the address databases are crucial for referencing thematic data in the urban system, it is important to see other options, related to other reference data and to the new technical possibilities, such as obtaining data for transport modeling from navigation systems. The efficiency of operation depends on provided cooperation in the databases and information processing instruments building. Both the investment in the quality of the reference databases, and in ensuring of their compatibility with the other data require a major effort, but it can give synergistic effects of unusually rich source of information supporting planning, spatial management, decision-making and related research.
