DESCRIPTION:Although it flows through the centre of the German capital\, th
 e Spree is a river that has so far attracted little interest from historia
 ns. Yet this almost 400 kilometre-long tributary of the Havel in eastern G
 ermany was and is not only central to ship transport and the supply of dri
 nking water and wastewater disposal for the city of Berlin. It is also at 
 the centre of the far-reaching changes to the landscape around the open-ca
 st lignite mine in Lower Lusatia\, of which it is the most important water
  drain. At the same time\, it irrigates the tourist attraction\, the Spree
 wald near Berlin\, and its lakes are an important recreational area for th
 e Berlin population. During the period of German-German division\, the Spr
 ee played an important role both as a barrier and as an escape route as a 
 river that did not respect political borders. Like many other rivers\, the
  Spree was straightened and dammed\, equipped with sluices and tunnelled u
 nder\, its banks fortified with walls and built on\, its natural course al
 tered\, especially in urban areas\, and its water polluted with filth and 
 chemicals of all kinds.\nHow could one write an environmental history of t
 he Spree that takes all these aspects into account and that at the same ti
 me makes the many facets of human perception of this 'lifeline' tangible? 
 One that consults not only traditional maps\, but also serial sources of a
 ll kinds that deal with the state of the river? That takes into account ve
 ry personal experiences with the river and also honours literary sources? 
 Which represents the various forces acting on the river - be they natural 
 or man-made? So much for the epistemological questions. But such a complex
  and colourful topic also deserves appropriate visualisation\, not least i
 n the form of maps. How can the spatial aspects of the river's history be 
 visualised in a compelling way? Are there cartographic methods that make i
 t possible to depict not only the multidimensionality of the history of a 
 river\, but also the diversity of experiences of its neighbours and users 
 over the course of history?\nSome more recent approaches to the integratio
 n of different levels in map visualisation are the concepts of 'deep'\, 't
 hick' or 'fuzzy mapping' developed mostly in the Anglo-American world. The
 y transcend the classic two-dimensional maps and depict historical process
 es in multi-dimensional views\, linking a wide variety of layers\, some of
  which are also intended to depict virtual realities. They are not limited
  to the representation of present and past realities\, but also include un
 realised spatial arrangements or future plans of a space or place.\nWhile 
 'deep' and 'thick mapping' have already been tested on a few historical re
 gions and locations\, fuzzy mapping\, which originated in the field of IT 
 and neurology\, has not yet been used to answer historical questions. The 
 method seeks to capture and depict causal knowledge and represent cognitiv
 e landscapes in the manner of neural networks and has been used to model d
 ecision-making processes in social and political systems. For the represen
 tation of structured knowledge and the modelling of complex systems\, the 
 method is attracting increasing research interest in various scientific di
 sciplines. With this task and the tools developed so far\, it should also 
 be possible to visualise environmental historical processes in the form of
  maps\, perhaps even better than is possible with existing methods.\nUsing
  the history of the Spree in the 19th and 20th centuries as an example\, a
  variety of different source and data resources (such as water levels\, le
 isure traffic\, pollution\, fishing results\, etc.) or even quotations fro
 m serial sources such as postcards\, inspection reports\, etc. will be int
 erlinked in the sense of 'deep' or 'thick mapping' in order to create a mu
 ltidimensional picture of the environmental history of the river\, its spa
 ce and its inhabitants. Finally\, fuzzy mapping will be used to visualise 
 development and decision-making processes with their causalities and drive
 rs and unrealised alternatives. The paper presents initial research result
 s and raises further methodological questions and problems.
