1. DESHADOWING OF HIGH SPATIAL RESOLUTION IMAGERY APPLIED TO URBAN AREA DETECTION
Abstract Different built-up structures usually lead to large regions covered by shadows, causing partial or total loss of information present in urban environments. In order to mitigate the presence of shadows while improving the urban target discrimination in multispectral images, this paper proposes an automated methodology for both detection and recovery

2. Spatial distribution of triatomines in domiciles of an urban area of the Brazilian Southeast Region
Reports of triatomine infestation in urban areas have increased. We analysed the spatial distribution of infestation by triatomines in the urban area of Diamantina, in the state of Minas Gerais, Brazil. Triatomines were obtained by community-based entomological surveillance. Spatial patterns of infestation were analysed by Ripley’s K function and Kernel de

3. Várzea do Carmo a Parque Dom Pedro II: de atributo natural e artefato - Décadas de 1890 a 1950 / Várzea do Carmo to Dom Pedro II Park: from natural attribute to artifact - Decades from 1890 to 1950
Com base na análise de uma amostragem significativa de representações visuais da região da Várzea do Carmo, porção da várzea do rio Tamanduateí entre o núcleo antigo da cidade de São Paulo e o povoado do Brás, a presente pesquisa trata da construção de diferentes imagens, no período entre as décadas de 1890 e 1950, sobre essa área que foi tr

4. CaracterizaÃÃo do uso e ocupaÃÃo do solo e qualidade da Ãgua com utilizaÃÃo das tÃcnicas de geoprocessamento. / Characterization of soil and water quality use and occupation based on geoprocessing technologies applications
the interest of many researchers who have studied the characteristics and environmental realities of agriculture in order to improve its sustainable development. Thus, this trial aimed at characterizing the use and occupation of soil and water quality according to the GIS techniques. Physical parameters as turbidity, temperature were analyzed as well as chem

5. Biotic factors and occurrence of Lutzomyia longipalpis in endemic area of visceral leishmaniasis, Mato Grosso do Sul, Brazil
The relationships between environmental exposure to risk agents and health conditions have been studied with the aid of remote sensing imagery, a tool particularly useful in the study of vegetation cover. This study aims to evaluate the influence of environmental variables on the spatial distribution of the abundance of Lutzomyia longipalpis and the reported

6. O DISCURSO DA CRIMINALIZAÇÃO DA JUVENTUDE NO JORNAL DAQUI
This paper aims at examining how young people are meant by the print media of Goiás, with particular emphasis on the quality of coverage of Daqui jornal during february, march and april 2010. I chose this subject because, according Waiselfisz (2011), in recent years (2004/2008) there is a frightening increase in the number of youth homicides in Brazil. The

7. BUILDING 3D DETECTION AND EXTRACTION IN INFORMAL SETTLEMENT AREAS / DETECÇÃO E EXTRAÇÃO 3D DE EDIFICAÇÕES EM ÁREAS DE ASSENTAMENTOS INFORMAIS
Informal settlements in many Brazilian urban centers are growing up quickly. Remote Sensing techniques provide a cost-effective mean to measure such an expansion. In cities with rough topography, like the city of Rio de Janeiro, the initial expansion, predominantly horizontal, is gradually being shifted to vertical, as new floors are being built on the exist

8. Mapeamento de cobertura vegetal do bioma Cerrado: estratégias e resultados.
ABSTRACT: Mapping Cerrado's vegetation cover is difficult because of its geographical extemt (~ 204,7 million hectares), high seasonality, and high spatial and temporal dynamics of its land use activities. The objective of this study was to map the vegetation cover of the Cerrado biome in the 1:250,000 scale using Landsat satellite imageries from the year of

9. Narrativas urbanas: cidade, fotografia e memÃria, Toledo- PR (1950-1980) / Urban narrative: city, photography and memory, Toledo-PR (1950-1980)
This paper aims to discuss and analyze some main photographs that were selected and arranged by articulating the history museum city of Toledo, images given as "official" or an "official memory" in order to realize their strengths in the formation of a social imagery and the city. Highlights a set of photographs (photographs expressed in albums, banners and

10. Classificação da cobertura da terra e do uso do solo urbano utilizando o sistema InterIMAGE e imagens do sensor QuickBird / Urban land cover and land use classification using the InterIMAGE system and QuickBird imagery
The object-based image analysis approach is presently the state of art for the classification of high spatial resolution imagery, specially in urban areas. Nevertheless, the cost of licenses of commercial software packages for these tasks is very high. InterIMAGE is an open source knowledge-based classification system whose image analysis concept is highly f

11. Estimation of retangular objects in high resolution images using template matching / Estimação de objetos retangulares em imagens de alta resolução utilizando casamento de modelos
The study of urban environment arouses great interest on remote sensing, given the social and economic implications of such application. Technological advances have increased the images generation with great capacity to discriminate Earth surface targets, which have been used to gather information about these areas. Every scene comprehension system has a set

12. INSTANTÂNEOS DO HOMEM PÓS-MODERNO: Uma leitura de O fotógrafo de Cristovão Tezza
This work proposes to analyze the human condition in big contemporary cities, considering, above all, the loneliness as a patent aspect in the urban person. When we point out the metropolis as a reliable place to the development of post-modern ideas and practices, we consider the city man as a product of this space and this context. Through the novel The pho
