Cartographers are facing several challenges in transforming geographic knowledge into interactive webmaps. Of course there are different webmapping technologies that can be used by everybody. Nevertheless implementing special forms of cartographic expression require cartographic knowledge as well as sophisticated programming skills and depend on technical limitations. This paper presents the newly developed cross-media production for the publication series 'Landschaften in Deutschland' (LiD) and discusses different webmapping solutions, their benefits and disadvantages as well as some challenges concerning prosumer-webmapping.
