This book gives a general picture of research-driven activities related to the context of location and map-based services. Such activities emerged in the last years especially around issues of positioning, spatial modelling, cartographic communication as well as in the fields of ubiquitious cartography, geo-pervasive services, user-centered modelling or geo-wiki activities. The innovative and contemporary character of the topics leads to a great variety of contributions in terms of interdisciplinarity, with such varying backgrounds as from academia to business, from computer science to geodesy covering an enormous number of topics. While contemporary cartography is aiming on looking at new and efficient ways on communication spatial information the development and availability of technologies like mobile networking, mobile devices or short-range sensors lead to interesting new possibilities of achieving this aim.
