As the INSPIRE Directive concerning creation of the European Spatial Data Infrastructure (ESDI) came into force on 15^th May, 2007, the Polish geodetic service has to face new challenges and tackle new goals. One of the more important and priority tasks is to prepare and harmonize a set of topographic reference data for Poland. The current situation, resulting from the lack of appropriate topographic reference data, forced the State Geological Institute (PIG) to collect its own spatial data necessary for performing its statutory activity. It developed its own standards and definitions of objects connected with spatial information. Topographic data collected by PIG are of relatively high quality and accuracy, thanks to field work carried out by documenting geologists permitting data verification in the field. This paper is devoted to a detailed comparative analysis of selected PIG databases carried out by the PIG Team, a geoenvironmental map of Poland, scale l :50 000 (MGśP) and a geologic and economic map of Poland, scale 1:50 000 (MGGP) with the TBD and VMap_L2+ bases (VMapL2 of the so-called second edition) as well as an assessment of possibilities of their integration within the confines of the future Multi-Resolution Topographic Database (WBDT). The PIG Team activities are connected with the implementation of a task within the confines of the designated grant KBN No 6T 12 2005C/06552 entitled „Methodology and procedures of integration, visualization, generalization and standardization of reference databases available from the state geodetic and cartographic resources and their use for creation of thematic databases".
