The Associazione Italiana di Cartografia ran a hybrid conference at the School of Humanities, University of Firenze. Two cartographic exhibitions were also conducted with the conference: an International Map Exhibition, held at the Italian Geographic Military Institute, and entries from the Barbara Petchenik Children’s Map Competition, shown at the Ex Circolo di Palazzo Medici Riccardi, both situated in Firenze
Automated generalisation to take fields into account : the GAEL model
No full textLa généralisation de données géographiques est l'opération de simplification de ces données effectuée lors de la diminution de leur échelle de représentation. Cette thèse s'appuie sur le modèle de généralisation automatique à base d'agents de (Ruas et Duchêne, 2007), qui a été mis en oeuvre avec succès pour la généralisation des objets géographiques discrets (bâtiments, routes, etc.). L'objectif est de permettre une prise en compte d'un nouveau type de thèmes, appelés "thèmes champ", comme le relief ou l'occupation du sol. Ces thèmes ont pour particularité d'être définis en tout point de l'espace. Nous souhaitons permettre une préservation des relations pouvant exister entre les objets géographiques et les champs, comme par exemple le fait qu'un cours d'eau s'écoule sur le relief. Pour répondre à cet objectif, nous proposons le modèle de généralisation GAEL (Généralisation à base d'Agents Elastiques) qui permet d'appliquer des déformations aux champs pour préserver les relations objet-champ. Les champs sont modélisés comme des agents, dits élastiques, qui ont la capacité de se déformer pour amortir les opérations de généralisation appliquées aux objets géographiques (bâtiments, routes, etc.). Ces déformations sont obtenues en s'appuyant sur une décomposition des champs en petits éléments contraints (points, segments, triangles, etc.) et sur une modélisation des points composant les champs sous forme d'agents. Couplé au modèle de (Ruas et Duchêne, 2007), le modèle GAEL permet de disposer d'un modèle de généralisation hybride, capable d'effectuer à la fois des opérations discrètes et continuesGeographic data generalisation is the process of simplification of these data when their representation scale decreases. This thesis is based on the automated generalisation model of (Ruas et Duchêne, 2007), which has been successfully applied to the generalisation of discrete geographic objects (buildings, roads, etc.). Our purpose is to take into account a new kind of themes, the "field themes", such as the relief and the land use cover. These themes have the specificity to be defined at each point of the space. We aim at preserving the relationships between geographic objects and fields, such as for example, the fact that a river should flow down on the relief. To reach this goal, we propose a generalisation model called GAEL (Generalisation based on Agents and Elasticity). This model allows to apply deformations to the fields in order to preserve the object-field relationships. Fiels are modelled as "elastic agents", which are able to deform themselves to propagate the generalisation operations applied on the geographic objects (buildings, roads, etc.). These deformations are performed by using a decomposition of the fields into small constrained elements (points, segments, triangles, etc.) and by modelling the points composing the fields as agents. Because it is merged with the model of (Ruas et Duchêne, 2007), the GAEL model offers a hybrid generalisation model, able to manage both discrete and continuous operation
L. Ruas' Linha d'água: proposal for a critical edition
No full textL. Ruas, besides being a poet, was a prolific chronicler, having published, during the 50s and 60s, in several newspapers in Manauaras. Some of them were collected in the book Linha D'Água, in 1970. In the present work, we propose a critical edition of this work, considering that it was published only once. Thus, we intend to unearth and value the chronicles of Ruas, which have great historical, literary and cultural relevance, since, besides the aesthetic quality, are the portrait of a Manaus that sought to modernize culturally. We also propose that six chronicles of the author, published in the Literary Supplement that the Club da Madrugada kept in the newspaper O Jornal, are added to the critical edition of the work. We believe, thus, to bring a new perspective on the chronicler L. Ruas, making an effort to avoid that his prose is forgotten in the ephemeral journalistic pages.
Keywords: Chronicle; critical edition; L. Ruas; Clube da Madrugada.L. Ruas, além de poeta, foi um prolífico cronista, tendo publicado, durante as décadas de 50 e 60, em diversos jornais manauaras. Algumas delas foram reunidas no livro Linha D’Água, em 1970. No presente trabalho propomos uma edição crítica dessa obra, tendo em vista que ela foi editada uma única vez. Dessa forma, pretendemos desarquivar e valorizar as crônicas de Ruas, que possuem grande relevância histórica, literária e cultural, uma vez que, além da qualidade estética, são o retrato de uma Manaus que buscava se modernizar culturalmente. Propomos, ainda, que seis crônicas do autor, publicadas no Suplemento Literário que o Clube da Madrugada manteve no periódico O Jornal, sejam acrescentadas à edição crítica da obra. Acreditamos, assim, trazer uma nova perspectiva sobre o cronista L. Ruas, realizando um esforço para evitar que sua prosa fique esquecida nas efêmeras páginas jornalísticas.

Experiências dançantes: corporeidade de sujeitos nômades
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Educação, Programa de Pós-Graduação em Educação, Florianópolis, 2011Esta dissertação teve como objetivo analisar os significados atribuídos à experiência de viver nas ruas pelos acolhidos na Associação Vida Nueva (AVN) localizada no município da Palhoça/SC, e como estes participam na constituição da sua corporeidade. A concepção metodológica configura-se como estudo de caso de abordagem etnográfica numa relação aproximada entre pesquisadora e os atores do contexto investigado, sendo utilizado como instrumentos de coleta de dados, diário de campo, documentos disponibilizado pela instituição, observações e entrevistas. No decorrer dapesquisa procurei legitimar os fios que configuram os modos de ser e estar nas ruas, marcado pelos deslocamentos infinitos. Os desdobramentos que compõem a caminhada tecem olhar sobre breve panorama da população em situação de rua; a estética das ruas e seus adereços, assim como o movimento das piruetas no trecho pelos protagonistas da pesquisa. Para análise foi privilegiado as narrativas de sujeitos que passaram e/ou estão na AVN, em especial dois deles, Val e Jota, denominados protagonistas desta pesquisa. Atítulo de considerações, esse estudo possibilita defender as imprevisibilidades inscritas na corporeidade dos sujeitos que passaram pela experiência de viver nas ruas e apropriam-se dos deslocamentos como legítimos de suas existências. As relações estabelecidas nas e com as ruas são afetadas pelas adversidades que a compõem pelos bons e ruins momentos. E a permanência em habitar as ruas, torna-se, algumas vezes, in-evitável pelo desejo-escolha de ali estar.The purpose of this dissertation is to analyze the meanings that individuals, who have been taken in by the Associação Vida Nueva (AVN) institution located in Palhoça SC, assign to the experience of living on the streets, and how these meanings take part in the construction of their corporeality. The methodology used for the research was a case study, with an ethnographic approach, that resulted from the relationship established by the researcher, the actors and the investigated context. The tools used for data collection includes a field journal, documents made available by the institution, observations, and information brought up in conversations with participants in different situations and opportunities. During this journey, I sought to legitimize the threads that shape the ways of being on the streets, marked by unlimited movements that place the individuals on the streets and stretches. I emphasized the developments that arrange the treks of each one of the participants, with analogies taken from a brief overview on street population. I added to my arguments a look at the esthetics adorning these streets, at the accessories decorating this lifestyle, and at the juggling movements that happen on the stretches traveled by the leading characters of this research. In the analysis, I highlighted the narratives by two individuals who are and/or were staying at AVN. They were called Val and Jota. As for the considerations, this study ventures to defend the idea that the unpredictable elements inscribed in the corporeality of individuals who lived on the streets are dimensions that encourage the movements and that make the self-perceptions, as well as the perceptions of the world, authentic. The affinities established on and with the streets are affected by the adversities they experience in their everyday lives, in which they dance between good and bad moments. This dissertation understands that the stay on the streets results in a living style that becomes an in-evitable welcoming made of desires, choices, addictions, sense of being there
Requirements for Planetary Symbology in Geographic Information Systems
No full textA large number of developments have significantly influenced digital mapping in the last few years which also affected the field of planetary mapping. Like in Earth-based geosciences the mapping nowadays are mainly conducted in Geographic Information Systems (GIS). In order to simplify the geological/geomorphological planetary mapping process on the mapper’s side, and harmonise the variety of mapping results we currently work on embedding a set of standardized mapping symbols within GIS. Such a symbol catalogue enables the user to visualise unit entities that were delineated during analysing and interpreting planetary surface in a homogeneous and cartographically correct way. As the symbols are to be used by different mappers at various locations, our main aim is to develop a portable symbol catalogue. In this context, we here describe a number of different approaches in order to find an efficient storage of symbol sets and to create an appropriate interface between a symbology layer and the (physical) underlying database model. This entire task forms one component in an overarching project that focuses on the generation of an extensible and modular geodatabase model to meet growing scientific and technical needs in planetary mapping
