Cartografia e georreferenciamento na geolinguística: revisão e atualização das regiões dialetais e da rede de pontos para a elaboração do Atlas Linguístico do Brasil formuladas por Antenor Nascentes.

Abstract

The studies on linguistic variations take into account diatopic, diastratic, diaphasic, diagenerational and diassexual factors, as well as the relations between them. In Brazil, some suggestions for dialectal divisions have been formulated, particularly the one developed by Antenor Nascentes (1953) in the second edition of ‘O Linguajar Carioca’ (Nascentes 1953). His study remains as the most quoted, commented on and used as reference for almost all geolinguistic studies. However, the description of the boundary lines proposed by his study referred to localities and geographical features (especially rivers and hills) which are not present in the accompanying map, and therefore cannot be appropriately reproduced. In addition to the aforementioned dialectal division, Nascentes presented a suggestion for a 'network of points' to be used in the gathering of data for the Brazilian Linguistic Atlas (Nascentes 1958). Like the other document, the network of points was elaborated according to toponymic features and political divisions. Due to several changes in the Brazilian political divisions between 1953 and today, these data do not correspond to the country's current toponyms and political-administrative divisions. This thesis presents a map of the dialectal division as well as 26 other maps with the suggested locations (one for each unit of the current federation), elaborated with automated Cartography resources, using GIS (Geographic Information Systems), a database resources, associating each element of the description to as much information as needed (attributes). These geographic, historical and socioeconomic informations are identified by their geographical coordinates (latitude and longitude), which guarantees the individual characteristics of identification for each one of them, therefore discarding any ambiguity problems. The observation of official Cartography in this map will allow that, at any given time, any locality or physical accident can now be identified and get new information associated with it. This will be the biggest difference between this map and all others published so far, allowing current and future generations of linguists to benefit from it.
