13. 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

14. A infografia como recurso comunicacional no processo de aquisição de informação e compreensão de tipografia
This exploratory study focuses on the use potential of infographics, visualization techniques and information design to enhance access to typography. An analysis and synthesis of methods is proposed and added to experience reports that guide the creation of informational graphics, from where the idea that the construction process and not only the query use o

15. Multi-channel azimuth processing in SAR images with emphasis on channel balancing alternatives.
Due to the widespread acceptance of Synthetic Aperture Radar (SAR) imagery by the scientific community in recent years, SAR system design faces ever increasing demands for wide coverage of high resolution images. This represents a challenging task, since conventional monostatic SAR system are inherently subject to a compromise between the achievable resoluti

16. Images aerophotogrametric and orbital in determining the use and occupancy of land and Permanent Preservation Areas (PPAs) / Imagens aerofotogramétricas e orbitais na determinação do uso ecupação da terra e de áreas de preservação permanente
With this study we evaluated the result of different methodologies in determining the use and occupancy of land and permanent preservation areas using digital aerial photographs with spatial resolution of 1m (scenario 01) and satellite imagery with a spatial resolution of 0.5 m ( scenario 02), photointerpreted screen, on a scale of 1:2000 mapping, watershed

17. La geología, geomorfología, pedología y uso de la tierra en las municipalidades de Puerto López (Colombia) y Uberlândia (Brasil)
On account of the precaution to raise the quality of life for people in Brazil and Colombia, isolated studies were developed to know the main human and physical resources and thus establish standards for proper management and exploitation of the territory. The aim of this study was to map and compare the geology, geomorphology, soils and land use and natural

19. Dynamic of Native forests in areas of Eucalyptus expansion in São Paulo State, Brazil / Dinâmica de florestas nativas em áreas de expansão de eucalipto no Estado de São Paulo
The expansion of the Brazilian silviculture has been developed in distinct steps, requiring a better understanding of its processes in space and time to qualify and quantify its impacts. As regards space, environmental questioning concerning the activity pushed the forestry industry for meeting environmental legislation. In Eucalyptus farms, a main concern w

20. Eliciting the evolution of spatiotemporal objects with case-based reasoning / Extração da evolução de objetos espaço-temporais com raciocínio baseado em casos
One of the main challenges in the information extraction provided by remote sensing images is to model and to represent geographical objects that have their properties changed along the time. This thesis proposes a novel approach based on Case Based Reasoning (CBR) for describing how geospatial objects identified in remote sensing imagery evolve. Given a set

21. 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

22. AGRO CLIMATIC ZONING FOR THE SUGAR-CANE CROP IN THE RIO GRANDE DO SUL/BRAZIL THROUGH OF THE GEOPROCESSING: CASE STUDY TO THE CONCIUL OF JAGUARI / ESTUDO DO POTENCIAL CLIMÁTICO PARA CANA-DE-AÇÚCAR (Sacharum ssp.) NO RIO GRANDE DO SUL POR MEIO DE GEOPROCESSAMENTO: ESTUDO DE CASO NO MUNICÍPIO DE JAGUARI
This work approaches an agro climatic zoning for the sugar cane crop (Sacharum ssp.) in the State of the Rio Grande do Sul Brazil through techniques of geoprocessing. The study was organized in thematic chapters including, in first, all municipalities of the State and, in a second moment, a rectangle centered in the municipality of Jaguari, main producer of

23. INVENTIVIDADE NA TV: A INVENÇÃO DO BRASIL
The proposal of this study is to reflect on the importance of the Brazilian television as skillful instrument of creation of imagery and cultural content, detaching and emphasizing the creative inventiveness of the producers. The strategy for this approach relies on the assumption that in many cases the television contributes to the Brazilian intellectual an

24. Road detection over informal settlements in a suburban area of Sao Paulo city by using high resolution satellite image and a object-based classification approach. / Detecção da malha viária na periferia urbana de São Paulo utilizando imagens de alta resolução espacial e classificação orientada a objetos.
Uncontrolled sprawl occurring in large cities of developing countries requires intensive mapping efforts to update geodatabases. The intense urbanization process experienced since the 70s in Sao Paulo city illustrates very well the reported scenario. Despite aerial data and, more recent, high spatial resolution satellite data which have been employed as basi
