“…One can be thorough by saying that for this same coordinate, the map by Father Fritz (1707) has precision of 1.00° (Cintra and Furtado, 2011) and even the map by La Condamine, due to the existence of an error of 3º in the mouth of the Napo River, has an average error of 1.14° (Cintra and Freitas, 2011). This occurred when he was working in 1744, some 80 years after Sanson and Pagan, and relying on advanced technology to determine longitudes, including the observations of Jupiter's satellites (with a luneta/telescope, with 18 feet of length), a good pendulum (clock), and calculations supported by the astronomical tables of Cassini.…”

One of the first scientific maps of the Amazon region, The Course of the Amazon River (Le Cours de La Rivière des Amazones), was constructed by Nicolas Sanson, a French cartographer of the seventeenth century, and served as the prototype for many others. The evaluation of this chart, until now, has been that it is a very defective map, a sketch based on a historical account, according to the opinion of La Condamine. Thus, the aim of the present work was to prove that the map of the Amazon River traced by Nicolas Sanson is a scientific work, a map that presents precise geographic coordinates considering its time, shows a well-determined prime meridian, and also employs a creative methodology to deduce longitudes from latitudes and distances that had been covered. To show such characteristics, an analysis of the accuracy of the map was made by comparing its latitudes and longitudes with those of a current map. We determined the prime meridian of this map and analyzed the methodology used for the calculation of longitudes. The conclusion is that it is actually a good map for the time, particularly considering the technology and the limited information that Sanson had at his disposal. This proves that the negative assertion of La Condamine is unfounded.KEYWORDS: Historical Cartography, Longitude, Accuracy, La Condamine, Pagan Nicolas Sanson e seu mapa: O Curso do rio Amazonas RESUMOUm dos primeiros mapas científicos da região amazônica (Le Cours de La Rivière des Amazones), elaborado por Nicolas Sanson, cartógrafo francês do século XVII, serviu de protótipo para muitos mapas da região. No entanto, a avaliação desse mapa, até o presente estudo, é que se trata de um mapa muito defeituoso, um esboço baseado em relato histórico, segundo uma apreciação de La Condamine que se difundiu até os nossos dias. Assim, o objetivo do presente trabalho foi provar que, pelo contrário, é um trabalho científico: um mapa que possui coordenadas geográficas precisas para a sua época, um meridiano de origem bem determinado e que empregou uma metodologia criativa para deduzir as longitudes a partir de latitudes e distâncias percorridas. Para isso foi feita uma análise da precisão desse mapa, comparando suas latitudes e longitudes com as de um mapa atual; bem como a determinação do meridiano de origem e a metodologia utilizada por esse cartógrafo para o cálculo das longitudes. A conclusão é que ele é um bom mapa para a época, tendo em conta as poucas informações de que o autor dispunha, e isso mostrou que são infundadas as apreciações negativas de La Condamine.

“…Finally, the presentation of the results was in 1745 including a map based on his observations. La Condamine was the person that took the measurements and the French geographer Jean-Baptiste Bourguignon d'Anville was the responsible to draw it (Cintra, 2011). The map includes the Pacific and Atlantic coast, it extended from the Spanish province of Quito in the west to the Portuguese city of Grão Pará (Belém) in the east, including the Guyanas to the north and parts of Brazil and Peru to the south.…”

Some of the main obstacles to the conquest and colonization of America by European powers were the scarce knowledge of the territory and the hostility of indigenous ethnic groups to its presence. Over the years, remarkable characters played the role of explorers and applying empirical methods began the survey of the territory, using the data collected and with the methods available on that time the first maps were delineated. Nearly two centuries passed and maps of South America with the Amazon River and its hydrographic basin as one of the centrals elements began to be produced by religious and scientific personalities. The purposes were totally different, but the expected result was a reliable representation of the area. Through the use of geographic information system programs and specialized software in map comparison, a temporal and comparative analysis of five old maps of the region published in the eighteenth century was carried out, with which in a graphical way the reader can visualize the updates of the mapped geographic elements and the accuracy of the work. Likewise, the selected area was digitalized and the basic cartography of each map with its respective database was created. In order to visualize the information generated through a virtual environment, a Story Map Journal in ArcGIS Online was created, it includes a summary about the life of each author, a description and the bibliographic reference of the map made, and the map compared to current data.

This thesis aims to analyze the sense of territoriality Portuguese in America, from the representations of space in the narrative and cartography the first half of the eighteenth century, dealing especially the Tocantins River region. Considering the discourse of territoriality is built through the production of knowledge about space, the analysis in question noted the ways in which narratives on the river Tocantins appropriated and produced information and knowledge that constituted a Portuguese means to identify the territory and to empathize with him. The perception of the first forays into the Tocantins River was highlighted with the intention of checking the penetration through the territory, followed by the colonization process and consolidation of Portuguese bureaucracy in the region of Goiás. The contrast between the colonized spaces and indigenous resistance, opposing "civilization" and "wilderness", involved in the advancement of Portuguese territory and the consolidation of the speech that imposed a new look at space. Also the geographical perception of the Tocantins River served as the base so that it could analyze the discourses identified in colonial narratives, especially the letter from Father Antônio Vieira (1653), the memory of lieutenant Silva Braga (1734) and "Defeat the Tocantins River "José Diogo da Costa (1735). This analysis has shown the organization of information about the river, as well as the representations built on space, in order to identify the sense of territoriality which was evoked in them. The emphasis on the itinerary of travel of Jose Costa Diogo ("Defeat of the São Francisco river" and "Tocantins river Defeat") allowed analyzing the special status of a producer of information on the area, whose narrative remained directly related to production cartographic the second half of the eighteenth century. In this perspective walked to the perception of the Tocantins river in the cartography of this period, by its absence or its presence by analyzing the special relationship case between narrative "Tocantins River Defeat" by José Costa Diogo, and Carte l'Amérique Méridionale, D'Anville (1748). It is concluded that the processes of production of knowledge about the area participate in the construction of meaning in discourse on territoriality, and the introduction of the Tocantins river in the cartography of the first half of the eighteenth century was the subject of this statement of the Portuguese territoriality in America.
