The article substantiates the relevance and expediency of prolonging the study of the processes of strategic, detailed and current planning of large, typologically differentiated forms of urbanization, as well as the implementation of urban planning documentation in the most developed countries of Northern Europe. The article presents the results of studying the specifics and trends of the formation, development and functioning of the system of spatial strategizing and urban planning and design in the Kingdom of Norway: its institutional, paradigm, technological and organizational components. It is shown that the significant differences between the Norwegian system of urban planning of large urbanized territories and its Danish, Swedish, and Finnish counterparts are due, on the one hand, to the national specifics of urban planning, and, on the other, to the relative independence of the spatial organization of the environment of Norway, a partner of the European Union, from the urban planning standards established for its members. It is noted that the basic trend of improving the system of long-term, medium-term, short-term and current planning in the Kingdom of Norway today is the achievement and approval of the parity of regional and municipal planning. It contributes to the "transparency"; predictability, humanistic socio-environmental orientation of urban planning policy implemented in this country, as well as initiates the search for various forms and increases the effectiveness of public participation in the processes of formation and implementation of urban planning decisions. The results of the study can serve as information-theoretical and methodological support for spatial strategizing and urban planning of priority and border geostrategic territories of Russia, which have long been part of the "Baltic Sea Civilization".
