The understanding of the geo-morphological characteristics allows the identification of flood areas and instability slopes among others important features for land use planning. The study of the hydrological net and the analysis of morphometric parameters help in the geomorphologic characterization, providing specific physics indicators that quantify the risks for environmental damages. The present work used Geographic Information Systems (GIS) and carried out the morphometric analysis of two watersheds in the Alto Rio Sorocaba, municipality of Ibiuna (SP). Using digitalized topographic bases in the scale 1:50,000, the main morphometric parameters were extracted and the Digital Elevation Model (DEM) was obtained. Hence the slope, ground illumination, hill orientation and relief feature maps were elaborated. The characteristics for the two watersheds were quite similar, both have low risks for floods and landslides. Therefore, the concave feature is the predominant hill shape for both watersheds. The morphometric parameters directly related to the river density of the watersheds showed some differences, because the Sorocabuçú watershed presents higher value, resulting in a higher level of relief development. Thus, with this characterization it is possible to provide subsidies for environmental planning actions to the area.

Outsourcing logistics has established itself in the area of the LSP (Logistics Service Provider), which offers a range of services to its customers. In this line, transportation is characterized as one of the most important services, and therefore efficient fleet management is essential for establishing a high level of customer service. With advances in technology and vehicle tracking systems, this approach of management has gained new possibilities for the improvement of logistics services. By studying the specific case of an LSP, this paper investigates the use of these technologies in the management of their business and services. The results indicate that the LSP seeks to increase its services and to streamline information in order to respond to customer needs in real time. It is also evident in this case under study that the combination of the technology available together with the fleet management system has become a distinguishing feature for this LSP, one which increases their skills and important information for both customers and business.

This study is based on the mapping of occurrences associated with social vulnerability and natural risks, which refer to the resilience of populations and territories, regarding natural hazards associated with the functioning of natural systems (eg, earthquakes, flood, mass movements). According to UNISDR (2014), the state of São Paulo is a reference in working with Urban Resilience and Disaster in the Resilient Cities Campaign (2014), considering the high investment in Risk Areas Mapping and Public Education Campaigns implemented by the Civil Defense. Thus, this study aims to mapping the occurrence of events related to Tree Falls, Erosion, Landslides, Irregular Housing, Rocky Blocks Falls, Wall Falls, Unroofing and Irregular Construction, attended by the Civil Defense in the city of Santos, São Paulo State, from 2011 to 2014. Thereafter, correlated analyzes to the Environmental Vulnerabilities were generated. The Environmental Vulnerability databases used in this dissertation compose the results of the CNPQ Project - Environmental Vulnerability Mapping of the State of Sao Paulo - Brazil: a methodological contribution of Freitas (2013) and Bortolettoet al (2014), with information collected from the 2010 Census (IBGE, 2010), on a census sectors scale. The adopted methodological procedure involves document analysis followed by data integration in Geographic Information System, through algorithms analysis and mapscrossing.The results obtained in Maps of Social and Environmental Vulnerability Occurrences presented areas of High or Very High Vulnerability. The main variables obtained with such characteristics are Irregular Housing, Landslides and Rocky Blocks Falls, which was associated with hilly terrain formations, with slopes above 30%.

Considering current technological progresses, they prove to be useful tools to be increasingly exploited in order to meet the population's needs. Generally, in Brazil, the Mobile Emergency Services (SAMU) tend to be limited to the management of incidents, which undermines the efficiency of these bodies. In this context, this final dissertation aims to present the use of Geographic Information Systems (GIS) for the SAMU in the cities of Feira de Santana BA and Rio Claro SP, integrating occurrences data related to trauma by cold weapon injuries, injury by gun, and assaults, in the period 2012-2013, as well as census data. The study was developed in stages that included obtaining data related to trauma events linked to urban violence, and statistical Census data (2010), provided by the Brazilian Institute of Geography and Statistics (IBGE). Regarding the GIS, the free software Quantum GIS (QGIS) was adopted for processing and spatializing data, assuming the districts as units of study, in the urban area of the cities analyzed. The resulting research products were presented in thematic maps format, which conducted to a comparative analysis of the occurrences related to traumas. The achieved results were satisfactory, and a database in GIS was developed, integrating occurrences data by Cold Weapon Injuries (FAB), Injury by Gun (FAF) and Assaults with census data, allowing the proper use and update of the system. Making a comparative analysis between the two cities, it was possible to establish that Rio Claro presents more occurrences when it comes to FAF, FAB and Aggression recorded at SAMU per 100,000 inhabitants than Feira de Santana. Thus, although Rio Claro's population is about three times smaller than Feira de Santana's, it can be said that Rio Claro is a more violent city, considering the factors analyzed. It is possible to infer that the use of GIS applied to the SAMU in medium-sized cities is feasible, and it has the advantage...

This study aims to perform the morphometric characterization of the watershed stream Petiço, Botucatu-SP, through techniques of GIS by GIS IDRISI Selva and Charter planialtimetric Botucatu (SF-22-ZB-VI-3) , edited by IBGE (1969), scale 1: 50000 for ranking the drainage network and the morphometric analysis. The variables analyzed were the dimensions, the relief pattern, pattern of the drainage network and the shape variables. The results show that related to how the watershed has an oblong shape with environmental interpretation with low tendency to flooding and erosion. The sinuosity index of 1.22 shows that the channels of the micro tend to be somewhat sinuous, which allows to infer that is permeable soil with good water infiltration. Based on the results of the morphometric variables was found that the watershed is in good condition of conservation, however, presents certain risks of susceptibility to erosion, and environmental degradation in some points, being fundamental to the maintenance of vegetation cover, in view of the roughness coefficient (Rn). Thus, the evaluation of morphometric characteristics in the study watershed constitutes an important tool in conjunction with the use of GIS and Geographic Information Systems makes possible the planning and management of natural resources aimed at their conservation.

The use of geographic information systems (GIS), combined with advanced analysis technique, enables the standardization and data integration, which are usually from different sources, allowing you to conduct a joint evaluation of the same, providing more efficiency and reliability in the decision-making process to promote the adequacy of land use. This study aimed to analyze the priority areas of the basin agricultural use of the Capivara River, Botucatu, SP, through multicriterial analysis, aiming at conservation of water resources. The results showed that the Geographic Information System Idrisi Selva combined with advanced analysis technique and the weighted linear combination method proved to be an effective tool in the combination of different criteria, allowing the determination of the adequacy of agricultural land use less subjective way. Environmental criteria were shown to be suitable for the combination and multi-criteria analysis, allowing the preparation of the statement of suitability classes for agricultural use and can be useful for regional planning and decision-making by public bodies and environmental agents because the method takes into account the rational use of land and allowing the conservation of hydrics resources.

Using the Geographic Information System (GIS) and taking into account its capability to analyze spatial data, a database of updated spatial data from the sub-basin of the Descalvado stream, Botucatu, SP, was developed to provide an evaluation and diagnosis of the area concerning land use and the degradation processes therein. Through GIS, priority areas for forest recovery were defined by Multicriteria Evaluation and using the Ordered Weighted Average method. The latter allows the decision maker to define the area to be recovered, facing limitation of resources, among one of the proposed scenarios, or do it in stages. The study showed that there are accelerated erosion processes in the headwaters of the springs of water bodies; there is also fragmentation of native vegetation, especially in hillside areas, and little presence of native vegetation in riparian areas. The application of the multicriteria analysis using the Ordered Weighted Average was important as it systematized and discriminated scenarios of priority for forest recovery.

A qualidade de vida para o ser humano depende do resultado das relações entre os processos biológicos, ecológicos, culturais e socioeconômicos que acontecem no espaço. Assim, a preocupação com a influência de zonas urbanas sobre o meio ambiente e a população tem sido um tema de crescente importância no Brasil, associando o desenvolvimento de novas políticas de gestão e reestruturação de grandes cidades. Nessa discussão, incluiu-se a questão da transformação da paisagem em ambientes urbanos, com impacto na manutenção dos serviços ecossistêmicos e na qualidade de vida da população humana. Este estudo propôs a caracterização da evolução da cobertura e uso do solo para a cidade de Carapicuíba, na Grande São Paulo, através da elaboração de seis mapas temáticos de uso e ocupação do solo do município, entre o período de 1962 e 2013. Além disso o projeto também pretendia fazer a modelagem de cenários futuros de mudanças, através de uma abordagem baseada no uso integrado de sensoriamento remoto, sistema de informações geográficas e modelos espaciais dinâmicos. Os mapas temáticos foram elaborados através de três mosaicos de fotografias aéreas adquiridas em 1962, 1972 e 1994, uma imagem orbital do sensor Ikonos de 2002, um mosaico de ortofotos aéreas adquirido em 2008, e uma imagem do sistema orbital RapidEye adquirida em 2013, para avaliação da dinâmica de ocupação da superfície da terra. As datas de imageamento disponíveis conseguiram representar momentos diferentes na história do município, referentes a acontecimentos importantes e que influenciaram significativamente na alteração da paisagem urbana: o grande crescimento demográfico e a construção das vias de acesso a Carapicuíba. As análises de dados e discussões apontam que o tipo de via de acesso à Carapicuíba e o tipo de uso do solo urbano, influenciaram na estratificação socioeconômica e na conservação de cobertura vegetal...
