Cartografias do invisível : para uma redefinição da serigrafia como meio operativo : a dissimulação da repetição

This dissertation searches for new possibilities into the way of operating with screen printing, as well as its importance in the context of the operational methods of the visual arts, based on a personal project of painting. To this end, we resource to the mapping and the linear drawings of city maps as a way to reflect upon its use in contemporary art. Also, we establish a connection between the way these cities organize themselves and the theories of the rhizome by Gilles Deleuze and Felix Guattari; the cartography and the grids of Rosalind Krauss, with the artistic aim to build screen printing matrixes; and also the function in gesture of making ‘printings’ with the conjectures of Didi-Huberman. We investigate also the consequences of a mode of doing by resourcing to screen printing with respect to the construction of visual metaphors in painting

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
