Avaliação do método de classificação baseada no objeto em imagens de alta resolução espacial aplicado para o monitoramento de faixa de dutos: estudo de caso no entorno da refinaria de Capuava em Mauá - SP

The metropolitan region of São Paulo is the most populous of the country, this happens because of its great importance in the national economy and the job opportunities that are offered to the population. These factors result in intense population growth and urban expansion, reaching some non-habitable places of the metropolis, as areas of pipelines, which are very important for the transportation of natural gas, oil and its derivatives. Before the population growth of the region, these sites were unoccupied, do not presenting problems for the population. However, with the disorderly occupation is generated great anthropogenic pressure on the pipeline stitches, causing risks to people who are around them. Therefore it is extremely important to monitor the strip of pipelines through products and techniques of remote sensing and geoprocessing, enabling, through high spatial resolution images, identification of objects or phenomena that occur on Earth's surface that can alter the functioning and safety of pipelines. Therefore, this study aims to monitor a stretch of the area of the pipeline mesh GASPAL/OSVAT and Capuava Refinery (RECAP), located on the outskirts of the metropolitan area of São Paulo in the city of Mauá, who suffer great human pressure, proving thus the techniques of remote sensing and geographic information system (GIS) as effective tools for monitoring phenomena occurred in urban areas of great complexity. The monitoring was done by object-based classification applied in orbital images Ikonos II and RapidEye, of high spatial resolution and, image processing, detection of objects, segmentation, classification and editing were developed through the eCognition and ArcGis softwares. To determine the statistical accuracy of the mapping of the land cover of the stretch of pipeline in Maua, the results were analyzed by error matrix...

População e áreas de risco: o caso das inundações na área central de São José do Rio Preto-SP

The problem of flooding in urban areas exist in many cities and their causes are as varied as the areas of occupancy or Valley weatherproofing Fund areas of infiltration in the drainage basin. The anthropic activity come triggering changes and impacts on the environment for a long time, and there is a growing need to come up with solutions and strategies that minimize and reverse the effects caused these risk areas. Thus, the present work will address the case study in São José do Rio Preto-SP that is an exception, since the area that is considered of risk lies in the Centre, unlike most lying on the outskirts. This will also analyze the processes of urban expansion and the situations of social and environmental vulnerability, including their interrelations in urban scale. The physical study of the area will serve as an important basis for the work, but it will focus mainly on the population and the problems which this is being in hazardous areas. We will not join a single methodology, wharever, we will follow our knowledge to adapt what we feel that fits better, every time. The importance of this study is that in addition to identifying the problems which the local population suffers with floods, lists measures that minimize the environmental impacts arising through the fostering of public policies

Resistências e transformações da organização agrária e histórico-cultural do bairro do Sobrado, Rio Claro/SP

O município de Rio Claro, localizado na região central do estado de São Paulo, durante o auge da era do café, da imigração tanto estrangeira como regional e da instalação de várias empresas, dentre elas a Companhia Paulista de Estradas de Ferro se urbanizou num acelerado ritmo, assim como tantas outras cidades do Brasil. Como resultado o aglomerado urbano cresceu, necessitando que seu perímetro expandisse para a zona rural, comprometendo tanto o seu patrimônio histórico quanto o cultural. Antigas propriedades datadas do final do século XIX que resistem à ação do tempo e mantém viva a riqueza e a cultura da época dão lugar à cidade. Esse processo é observado no bairro rural do Sobrado, localizado na região norte de Rio Claro, que vem sofrendo diretamente com a expansão urbana através da criação de novos loteamentos residenciais e comerciais. Portanto, o avanço da urbanização tem provocado à degradação e/ou desaparecimento dos fatos históricos e culturais ainda presentes nos bairros rurais do município

Efeitos da ocupação e uso da terra na bacia do córrego da Servidão, no cenário de 1995-2006

Urban sprawl developed without adequate urban planning and lack of knowledge about the physical characteristics of an environmental system, results in soil sealing and consequent change in the dynamics of hydrological watershed. Thus, this study aimed to analyze the behavior of the runoff basin Cóorego DA Servidão located in Rio Claro, referring to the year of 1995 compared to the scenario of 2006, compared the different features of urban use logged area. Therefore understanding the dynamics of the flow was possible through the use of software IPHS 1 that allowed through hydrologic models to evaluate the behavior of the surface area investigated, using Spring 4.3.3 software which enabled the classification of land use and software ArcGis 9.3 which was used for the quantification of stretches of water, separated from those that are channeled and those who did not suffer interference from the pipe

Chuva, vulnerabilidade social e percepção do risco na cidade de São Paulo: impactos de eventos extremos nos bairros da Freguesia do Ó e do M’Boi Mirim

The city of São Paulo has, since the beginning of the expansion of its urban sprawl, represented relations of conflicts and contradictions between society and nature. Once the way society relates to nature is defined by how the social agents themselves correlate in certain social and historical contexts, the ways of interaction between the social and natural elements will be different according to the forms of production and appropriation of the urban space. Even more evident is the case of the great national metropolis, given its demographic dimensions and historical conditions, the process of urban expansion follows a logic where spaces of better quality for housing are occupied by those of better financial conditions. Thus, although there are exceptions, the poorest people live in places less desirable, in less resilient environments of lower environmental quality, relating to nature and its phenomena with greater risks. These risks are reflected here as recurring flooding, mudslides and landslides for which the rain is constantly blamed. So we have a situation where it is clear that a weather phenomenon differently interacts with different social groups. In this context, the study was conducted to compare extreme events occurred in two regions of São Paulo: the Freguesia do O, in the north side, and M'Boi Mirim, in the south side. Both are regions with large number of risk areas and are in the same urban climate unit. However, they present different conditions of social vulnerability. With the investigation of each extreme rain event occurred in the two regions, in the period of 2000-2010, supplemented by field research, we tried to observe how far the rain, with his intensity and volume, can, in fact, be related to the accidents.

Diagnóstico Ambiental da Cidade de Presidente Bernardes - SP

The new modes of production imposed by capitalism and its relentless pursuit of development triggered several impacts on the natural environment and thereby the quality of life of society. These impacts become more visible when we look the urban place. For the identification and proposal of solutions is necessary to carry out an environmental diagnosis to have knowledge of the real situation of a given area. The Presidente Bernardes city is located in West of the São Paulo State, and even being a small city has many problems resulting of the unplanned urban growth. Thus, the present work intends to conduct an environmental diagnosis of the city Presidente Bernardes-SP, through the analysis of water supply systems, sewage treatment, collection and disposal of solid waste and green areas in the urban area and if required, indicate plausible alternatives to solve any problems

Determinação de áreas prioritárias para conservação na zona de amortecimento de UC de proteção integral: o caso da Estação Ecológica de Ribeirão Preto, SP

Observa-se como estratégia mundial para a conservação da biodiversidade a criação de unidades de conservação. No Brasil, especificamente no Estado de São Paulo, devido a intensa degradação da Mata Atlântica, verifica-se a criação de unidades de proteção integral, a fim de se preservar de modo restrito os recursos naturais que ainda lhe restam. Na cidade de Ribeirão Preto, uma região com alto desempenho agrícola e intensa expansão urbana, constata-se a presença de uma Estação Ecológica (EERP), fragmento florestal de 154,16 ha, altamente isolado e fragmentado. Assim, a EERP e sua zona de amortecimento (ZA) vêm sendo fortemente pressionada pela expansão urbana e agrícola da região, comprometendo a sua integridade ecossistêmica. Dentre os impactos negativos gerados destacam-se: alta especulação imobiliária e o intenso cultivo de monoculturas, que contribuem para a degradação do solo nas regiões do entorno. A fim de se reduzir tais impactos, o presente trabalho buscou apresentar um prognóstico de planejamento ambiental para a ZA da EERP, a qual se encontra altamente impactada, segundo os critérios definidos por Ranieri (2004). Desse modo, criou-se cenários ideais para a preservação dos recursos naturais do local
