The paper presents the role and significance of standards of geographic information for technical (in geodesy and informatics) aspects of designing, building, maintaining and using spatial information infrastructures at European, within the programme INSPIRE, as well as at national, scale. In both cases the role and significance consist in formulating methodological and technological conditions necessary to provide interoperability of GIS in separate implementations and topics. The essence of the standards is conceptual modeling, based on object oriented methodology and supported by formal languages UML and XML/GML. There is also given a general outline of the methodology. Finally, the paper presents a general structure of international standards (ISO) for geographic information, which are the basis of European standards (CEN) mainly for use within INSPIRE. They hale been alredy approved as Polish standards, as well.
