This book constitutes the proceedings of the 12th International Conference on Spatial Information Theory, COSIT 2015, held in Santa Fee, NM, USA, in October 2015. The 22 papers presented in this book were carefully reviewed and selected from 52 full paper submissions.

This book gathers a selection of the best papers presented during the 14th International Conference on Location Based Services, which was held in Zurich (Switzerland) between the 15th and 17th January 2018. It presents a general overview of recent research activities related to location based services. Such activities have grown in importance over the past several years, especially those concerning outdoor/indoor positioning, smart environments, spatial modeling, personalization and context-awareness, cartographic communication, novel user interfaces, crowdsourcing, social media, big data analysis, usability and privacy.

The GIScience conference series (www. giscience. org) was created as a forum for all researchers who are interested in advancing research in the fundam- tal aspects of geographic information science. Starting with GIScience 2000 in Savannah, Georgia, USA, the conferences have been held biennially, bringing together a highly interdisciplinary group of scientists from academia, industry, and governmentto analyze progressand to explore new researchdirections. The conferences focus on emerging topics and basic research ?ndings across all s- tors of geographic information science. After three highly successful conferences in the United States, this year’s GIScience conference was held in Europe for the ?rst time. The GIScience conferences have been a meeting point for researchers coming from various disciplines, including cognitive science, computer science, engine- ing, geography,information science, mathematics, philosophy, psychology,social science, and statistics. The advancement of geographic information science - quiressuchinterdisciplinarybreadth,andthisisalsowhatmakestheconferences so exciting. In order to account for the di?erent needs of the involved scienti?c disciplines with regard to publishing their research results, we again organized two separate stages of paper submission: 93 full papers were each thoroughly reviewed by three Program Committee members and 26 were selected for p- sentation at the conference and inclusion in this volume. Then, 159 extended abstracts, describing work in progress, were screened by two Program Comm- tee members each. Subsequently, 42 of them were selected for oral presentation, and 46 for poster presentation at the conference.

This book constitutes the refereed proceedings of the Third International Conference on GeoSpatial Semantics, GeoS 2009, held in Mexico City, Mexico in December 2009. The 10 revised full papers presented together with 2 keynote speeches were carefully reviewed and selected from 19 submissions. The papers are organized in topical sections foundations on geo-semantics; formal representation of geospatial data; semantics-based information retrieval and recommmender systems; integration of sematics into spatial query processing; and geo-ontologies and applications.

20 years ago, from July 8 to 20, 1990, 60 researchers gathered for two weeks at Castillo-Palacio Magalia in Las Navas del Marques (Avila Province, Spain) to discuss cognitive and linguistic aspects of geographic space. This meeting was the start of successful research on cognitive issues in geographic information science, produced an edited book (D. M. Mark and A. U. Frank, Eds., 1991, Cognitive and Linguistic Aspects of Geographic Space. NATO ASI Series D: Behavioural and Social Sciences 63. Kluwer, Dordrecht/Boston/London), and led to a biannual conference (COSIT), a refereed journal (Spatial Cognition and Computation), and a substantial and still growing research community. It appeared worthwhile to assess the achievements and to reconsider the research challenges twenty years later. What has changed in the age of computational ontologies and cyber-infrastructures? Consider that 1990 the web was only about to emerge and the very first laptops had just appeared! The 2010 meeting brought together many of the original participants, but was also open to others, and invited contributions from all who are researching these topics. Early-career scientists, engineers, and humanists working at the intersection of cognitive science and geographic information science were invited to help with the re-assessment of research needs and approaches. The meeting was very successful and compared the research agenda laid out in the 1990 book with achievements over the past twenty years and then turned to the future: What are the challenges today? What are worthwhile goals for basic research? What can be achieved in the next 20 years? What are the lessons learned? This edited book will assess the current state of the field through chapters by participants in the 1990 and 2010 meetings and will also document an interdisciplinary research agenda for the future.
