“Maritime regionalism has a long tradition and is part of many policy documents but with confusion and a lack of accuracy [1]. This is a weakness in the implementation of marine spatial planning which has a strong need for the Z-VAD-FMK research buy delimitation of spaces and sub-spaces in various ways. Marine spatial planning needs not only defined spaces where administrative processes can be handled efficiently, it has a need also for meaningful delimitations of planning areas based on spatial characteristics, spatial connectivity and on relations between areas. In land based planning spatial typologies are often key building blocks in developing plans

and in distinguishing areas in need of different types of planning Thiazovivin cell line response. It frequently makes distinctions for example between urban and rural areas and central business and industrial

districts [2]. Not only do the aims and visions but partly also old the tools and mechanisms of spatial planning differ depending on the character of the area worked with. Marine spatial planning has yet no commonly recognized categories such as these. In some examples planning areas are defined by legal/administrative borders only (e.g. Massachusetts, Germany). In England, however, although the Marine and Coastal Access Act 2009 restricts marine plans to be within a single marine administrative region (either inshore or offshore), data analyses of human activities and spatial relations [3] has led in some cases to the development of coordinated adjacent plans in inshore and offshore areas at the same time through a single combined process (e.g. East Inshore & East Offshore planning areas) despite of legal constraints [4]. Obviously therefore knowledge about spatial characteristics can have an impact on the design of planning processes as well as on the content of spatial plans. In general spatial planning and also environmental management has developed various ways to comprehend and to analyze the characteristics of different spatial structures [5], [6] and [7]. In particular, during the late 1960s the use of quantitative analysis emerged to assist spatial planning in this way [8]. Since then inter-regional comparisons and spatial typologies based on statistical methods have become common tools [9]. Nonetheless, their use in marine spatial planning is still limited [10].
