O crescimento das sociedades urbanas tem gerado um aumento significativo na produção dos resíduos sólidos urbanos, tornando o tema de disposição final amplamente discutido nas gestões públicas. Recentemente, a partir da criação da Lei Federal nº 12.305/2010, que institui a Política Nacional dos Resíduos Sólidos, foi estabelecido que a disposição final ambientalmente adequada dos rejeitos deve ser feita exclusivamente em aterros. O presente trabalho teve então como objetivo a avaliação de áreas potenciais para instalação de aterro sanitário no Distrito de Floresta do Sul no município de Presidente Prudente/SP. Para tanto, utilizou-se o SIG, como ferramenta do geoprocessamento, para análise espacial. Inicialmente, construiu-se um banco de dados geográficos da região de estudo com os dados de geomorfologia, hidrologia, declividade, malha urbana e rede viária. Em seguida, foram geradas representações na categoria MNT, onde os valores foram normalizados em intervalos [0,1] através da lógica booleana e fuzzy...

This paper discusses about the use of remote sensing image and processing digital images tools for mapping and assessing the effect on the biomass of the culture of sugar cane in the city of Rio Claro. We used satellite images from CBERS in the passages of 19/04/2009 and 23/09/08, which correspond respectively to the stages where the sugar cane appeared in growing and adult pre-harvest stage. In these images, we applied procedures of digital processing, as the application of the procedures for extending linear contrast, radiometric normalization, Normalized Vegetation Index (NDVI) and pixel by pixel classification by ISOSEG through of the software SPRING. As a result we obtained mapping of the distribution and development stages of the culture of sugar cane in the city of Rio Claro and the mapping of the existing biomass of this culture, showing that the method used to assess the relative effect on biomass in culture of sugar cane was efficient, and that images of low-medium resolution are not the most suitable for the mapping of this culture

Os processos geomorfológicos são responsáveis pelas formas do relevo, constituindo uma das dimensões do substrato físico para o desenvolvimento das atividades antrópicas. O conhecimento e a identificação dos mecanismos destes processos podem contribuir para o entendimento das dinâmicas naturais e das ações humanas sobre a superfície terrestre. Desta forma, objetivo desse trabalho de pesquisa foi identificar e caracterizar as principais unidades geomorfológicas do baixo curso do rio Paranapanema, a partir da utilização dos Sistemas de Informação Geográfica (SIG) e do uso de geotecnologias. No SIG foram realizadas as seguintes etapas da pesquisa: processamento digital das imagens de radar, georreferenciamento dos dados, delimitação e compilação da área de estudo e elaboração dos mapas temáticos. Os procedimentos metodológicos adotados fundamentaram-se basicamente nos conceitos de morfoestrutura e morfoescultura para classificação e taxonomia do relevo, desenvolvidos por Jurandir L. S. Ross (1992). As classes de dissecação do relevo, carta clinográfica e hipsometria da bacia foram obtidas a partir do processamento de cartas topográficas e imagens de radar da missão SRTM. Os resultados apresentados na forma de mapas, gráficos e tabelas permitiram analisar e caracterizar os processos geomorfológicos atuantes na bacia do baixo Paranapanema, com maior riqueza de detalhe (1: 250 000)

The demographic census is the largest and most important socioeconomic research of the country since it portrays the situation closer to the reality of the population. Their result allows public policy making aimed at improving the quality of life, socioeconomic development and provides information for decision making on public and private sector. Due to the large amount of data collected, the processing of such information requires increasingly use information technology to facilitate processing. Therefore, the increasingly common use of the Geographic Information System (GIS) in various fields of knowledge contributes to the job achievement given its ability to collect, store, retrieve and view data. Following this trend, the Brazilian Institute of Geography and Statics (IBGE) also used this tool in the development of cartographic inputs, wich plays a key role for the data collection range nationwide

Suitable computacional tools allow to build applications that can link information to its physical location, and represent them into visual and interactive schemes, e ectively reaching the power of visual comunication. This leads the user to synthesize information in a simple and e cient way. These applications are linked to the de nition of Geographic Information System (GIS). GIS are comprised by many concepts and tools, which have the main purpose of collecting, storing, viewing and processing spatial data, obtaining the information needed for decision making. Within this context, this paper presents the Conception and Implementation of a Control System for Urban Forestry through Integration of Free and Open Source Software. This conception arose from the need of an Environmental Project developed by the Agriculture's House of the city of Regente Feij o, which has as main objectives cataloging and management of urban a orestation of the municipality. Due to this diversity of concepts, the challenge in building this system is the integration of platforms that are involved in all stages: collecting and storage of data, including maps and other spatial information, operations on the stored information, obtaining results and graphical visualization of the same. After implementation, it was possible to provide for the system users an improvement in the capacity of perception in the information analysis and facilitate the process of decision making

Management information systems such as ERP can bring to businesses many competitive advantages. There is a great demand for systems projects to consulting firms that have knowledge to manage this particular type of project. However, the rate of system projects that cannot achieve success is very high. The methodology of Project Management, standardized by the Project Management Institute, is a globally recognized standard and used even in projects involving information technology. In the present study, was made a case study of an ERP system implementation project in a large company, by a consulting firm. From this analysis and on contributions from the literature, recommendations were proposed for the project management, in order to better direct the PMI methodology in large projects involving systems like ERP

Innovation in the field of Information Technology (IT) have made companies evaluate their processes and activity of its supply chain to conform to this new reality. In the supply chain management, one of the tools that revolutionized the activities was the use of management information systems such as ERP tool. This system allows greater integration of data from multiple areas of the enterprise and beyond, giving more activities to processes and activities. This work aims to analyze the results and impacts of the restructuring of an equipment leasing process in a Brazilian media company and verify that the gains and improvements that were targeted in the initial design of this restructuring have been achieved. Also the risks identified with this change will be studied, the reactions of those involved in this process and the performance of the chain as a whole. To carry out this work was carried out a single case study with data collection in the assessed company and literature related to supply chain and information systems
