Do arquivo ao novo : impactos da tecnologia digital no armazenamento e disseminação da informação na cultura contemporânea

While taking paths from the archive to the new, this dissertation reflects on the resulting impacts of the introduction, massification and dissemination of digital technology, in the way we store and deal with information, inside the complex that we understand as culture. To this end, a theoretical investigation is performed in order to build a conceptual body from which concepts are drawn in order to effectuate a practical research. The theoretical research starts with an exordium in which the concept of the archive is deconstructed in order to identify it as a device of power and to analyse its transition from a technical analog object into a digital technology. Following this, a historical context is established, drawing on the evolution of power exercises and apparatuses, and a reading of the impacts of the present technological mediation on experience, knowledge cons¬truction and forms of control is developed. Finally, some hypotheses on the evolution of technology are formulated. The practical research materializes in the form of a digital platform which takes place in two moments: one of archive, the other of program. The first moment, of archive, con¬sists of a repository of projects dealing with the dissertation’s subject. The second moment, of program, is configured as a cultural program implemented through computer programs. These, in their execution, result in performances which, taking from the information col¬lected on the archive generate a new experience of that same information. To this effect, a framework was structured in order to have computational processes systematized in a way that the performances result in experiences with a potential for novelty, expression and reflection. Both theoretical and practical components of the research seek to address digital technology not as an end in itself, but as a factor that affects human experience and behaviour

Selfmapping : o mapa colaborativo como medium de visualização espácio-temporal

THE MAP AS A COLLABORATIVE MEDIUM FOR SPATIO-TEMPORAL VISUALIZATION This dissertation focuses on the relationship between maps and spatio-temporal data visualization. It is divided into two components: theoretical framework and practical approach. The study begins by questioning the role of the map in today’s digital society and particularly its role in visualization, and finishes with the conceptualization and development of an interactive dot map that visualizes data from Instagram and Twitter. Nowadays, geographic information is no longer produced just by experts, but also by ordinary people that are able to participate in data creation and exchange. The Web 2.0 lies in the heart of this change, where social media represent a significant tool for producing geotagged content, allowing its users to share their location and to spatially reference their publications. Furthermore, amateur mapmaking and neogeography have benefited from the emergence of several new devices that enable the creation of digital maps that are interactive, adaptable and easily shared on the Web. This study adopts a descriptive approach calling upon the diverse aspects of the map and its evolution as a medium for visualizing geotagged data, highlighting collaborative mapping as an emerging subject area that is of mandatory future research. Relevant projects are also analyzed in order to identify trends and different approaches for visualizing social media data in its spatial context, intended to support the project’s conceptualization, development and evaluation. The created map demonstrates how spatial knowledge and perception of place are now redefined by the contributions of individuals; it also shows how that activity produces new sources of geographic information, forcing the development of new techniques and approaches that allow an adequate exploration of content and visualization methods of the contemporary map
