In order to define databases and computer tools supporting the planning and spatial management process, analysis of various conditions is needed. The paper, focusing on the most important ones, presents the following elements: 1.analysis of development of the spatial planning process, of requirements of progressing e-administration and evolution of information society, 2 consequences of the past . problems resulting from the necessity of operating on plans processed in different technologies, 3 requirements resulting from different ways of using the local plan (as a legal document and as basic instrument of spatial management in the commune). In consequence, alternative methods of recording plans and techniques of making their content accessible to different groups of users were proposed. The list of GIS-based computer tools assisting various tasks of spatial management related to the instrument of local plan was formulated. Some of the tools deal with monitoring and management of plan elaboration, others support the process of plan elaboration (analyses, modelling and plan recording) or the process of plan realization. The paper presents examples of such instruments implemented in Wroclaw, their functionality and basic technical solutions. Among them, there are solutions which have been developed for several years, as well as new ones being implemented at present. All of them are integrated with Wroclaw Urban Spatial Information System (WPSIP). The need to support planning and spatial management has basic influence on planned directions of evolution of the urban spatial information systems. We can observe again the double character of supported tasks: these connected with administrative procedures and those related with planning, analyses and decision making. The requirement to conduct reliable analyses influences detailed requirements concerning particular data resources., These data resources include, among others: 4 municipal registers (and related databases): register of local plans, registers of decisions and applications, 5 reference datasets received from outside or collected by the city (address database), 6 systematically updated data of the state of the city and environment (orthophoto, 3D model), 7 registers of objects and areas protected, other registers and thematic bases run by external organizations or in cooperation with the city, 8 information about different urban systems, their current condition and plans of future development. Some of these requirements and attempts to cope with them are presented on examples of WPSIP data.
