Open Data from Social Media as Tool for Better Understanding Complex Territory Application through Photos Data in Calabria

摘要

Data are becoming increasingly important nowadays, because they represent a concrete and inexhaustible source of information, which could be transformed into knowledge. Then, knowledge is synonymous with resource, because it represents a source of personal and community enrichment and, at the same time, it allows to accomplish more aware actions and to take advantage of every moment of freedom that comes from it. Thanks to today's technology, that creates services in response to the growing needs of citizens, public administrations and companies, the value of these data is finally disclosable in simple and immediate ways. An important tool, particularly with regard to more precise issues, such as security, economy or quality of life, is Geographic Information System, since it allows not only to represent the collected data in an immediate way, but above all to provide it with georeferencing, and, then, to spread it through mappings, easily interpreted also by non-experts. In particular, research is always more interested in big and Open Data; for this reason, the present work aims to analyze a significant amount of information on geo-referenced data in order to provide a broad view on issues related to tourism flows, in a reality such as Calabria, an Italian region, which is configured as a territory characterized by complex interactions and dynamics.
