He was elected member of the National Academy of Sciences and Foreign Member of the Royal Society of Canada in 2002, member of the American Academy of Arts and Sciences in 2006, and Foreign Member of the Royal Society and Corresponding Fellow of the British Academy in 2010; and in 2007 he received the Prix Vautrin Lud. He was editor of Geographical Analysis between 1987 and 1990 and editor of the Methods, Models, and Geographic Information Sciences section of the Annals of the Association of American Geographers from 2000 to 2006. He serves on the editorial boards of ten other journals and book series, and has published over 15 books and 500 articles. He was Chair of the National Research Council’s Mapping Science Committee from 1997 to 1999, and of the Advisory Committee on Social, Behavioral, and Economic Sciences of the National Science Foundation from 2008 to 2010. His research interests center on geographic information science, spatial analysis, and uncertainty in geographic data.Alessandro Annoni is working in European Commission’s Joint Research Centre since 1997. He has been the Head of the Spatial Data Infrastructure and the Digital Earth Units working on Information Infrastructures, advancing research on multidisciplinary-interoperability and ensuring the Technical Coordination of the INSPIRE Directive 2007/2/EC that lays down rules for the establishment of the European Spatial Data Infrastructure. Since 2016 is the Head of the Digital Economy Unit targeting the impact of Digital Transformation on economy and society and in charge of the European Artificial Intelligence Observatory (AI Watch). Alessandro graduated in Physics from the University of Milan. Before joining the European Commission, he worked for 20 years in the private sector and managed companies dealing with Digital Earth technologies. Alessandro has 40 years working experience in several domains (forestry, agriculture, oceanology, nature protection, … and more recently on digital economy) dealing with Spatial Planning, Spatial Analysis, Environmental Modelling, Spatial Data Infrastructures, Geo-Information, GIS technologies, Artificial Intelligence, Remote Sensing, Image Processing, System Design and Software Development. He has participated in several European projects relevant for Geo-Information and Digital Technologies and is author, co-author and editor of more than hundred papers and books. Since 2006 Alessandro served as co-chair of the Architecture and Data Committee of the Group on Earth Observations (GEO). He co-chaired the GEO Infrastructure Implementation Board and he is now member of the GEO Programme Board. He is a visionary member and Vice President of the International Society for Digital Earth (ISDE). Alessandro has been awarded the 2013 Ian McHarg Medal of the European Geosciences Union reserved for distinguished research in Information Technology applied to Earth and space sciences. In 2016 he received the Digital Earth Science and Technology Contribution Award from the International Society for Digital Earth for outstanding contribution to advancing the development of Digital Earth.
