O presente estudo foi realizado na Bacia Hidrográfica do Rio Passa-Cinco, onde existem elementos da paisagem de grande interesse ecoturístico, além de patrimônios naturais que, se preservados e aproveitados mediante ações de gestão ambiental serão potenciais agentes de desenvolvimento sustentável na região. Apesar da área possuir atrativos naturais como cachoeiras, corredeiras, cavernas, canions, lagos, paredões, mirantes, entre outros, indicando alto potencial de uso sustentável do ponto de vista ecoturístico, a região ainda não recebeu investimentos suficientes para que toda a diversidade paisagística seja usufruída. Portanto, este trabalho tem o objetivo de elaborar um Inventario Ecoturístico da Bacia do Rio Passa-Cinco, inserido nos municípios de Itirapina-SP e Ipeúna-SP, utilizando ferramentas de Geoprocessamento. Para tanto, realizou-se um trabalho de campo com visita aos locais que apresentam valor cênico considerável e potencial ecoturístico. Os locais identificados e visitados foram caracterizados usando fotografias, textos explicativos, tabelas e MDTs (Modelo Digital de Terreno). A integração destas informações constitui um Banco de Dados Geográfico Digital Georreferenciado (BDGDG) em ambiente ArcGIS 9.0, disponível em http://ceapla.rc.unesp.br/atlas/. Os resultados obtidos subsidiam ações de gestão ambiental, como o planejamento ecoturístico na bacia, favorecendo o desenvolvimento sustentável das comunidades envolvidas. Palavras-chaves: Bacia do Rio Passa-Cinco, Inventário Ecoturismo, Geoprocessamento, Banco de Dados Geográfico Digital Georreferenciado.

The style of life in the cities deprives the man of the contact with nature. As a way to escape from the turbulent reality of the urban system, the urban planning provides areas that allow the contact between man and nature like botanical gardens, parks, leafy squares, etc. These places, through specific analysis, are also called green areas. Thus, the main purpose of this research is to outline and analyze, through geoprocessing techniques, green areas of Americana, São Paulo considering them as indicators of urban environmental quality. This evaluation will be based on the methodology adapted by Bargos (2010) where products of remote sensing were used (aerial photos and satellite images) and it will be also based on field work and calculation of the amount of green areas. The software ESRI ArcGIS® will be used to create thematic maps connected with city’s green areas. Based on the results achieved in this study, it’s expected to contribute to the government of the city of Americana in order to provide benefits of analysis for decision makers in the context of urban planning aiming an improvement in the urban environmental quality, thus benefiting its entire population

The objective of this research was to conduct an analysis of multitemporal landscape Ipanema National Forest, located in the municipalities of Iperó, Capela do Alto and Araçoiaba da Serra – São Paulo estate, Brazil, considering the scenarios of 1965, 2007 and 2011. The multitemporal analysis, using aerial photographs and satellite images, contributed to the contextualization and spatialization of the evolution of the landscape area. Through analysis interpretation of the images, performed by means of supervised classification were obtained thematic maps of the area, equivalent to approximately 53 km2. Through geoprocessing techniques, especially Geographic Information Systems, it was possible the integration and manipulation of data, both spatial and statistical, allowing integrated analysis of data from the entire area of the National Forest of Ipanema. As the main result, we found that the Ipanema National Forest is in landscape evolution positive, with those 46 years examined the increase of native heavy foliage areas. Increasing from 7.1 km2 of the total area of dense vegetation in 1965 to 35.9 km2 in 2011. Overall, it was possible to realize a scenario landscape quite optimistic about the evolution of forest conservation area

Sugar cane production is of the utmost importance to the economy of the entire Brazil, due to its multiple utility, being used as the raw material for the manufacture of various items, particularly, sugar and alcohol. In areas of sugarcane monoculture, the appropriate management of soils and water is essential, not only for the maintenance of the quality of the environment, but also for the quality of life of the population. Among the main impacts generated by the cultivation of sugar cane, stands out the withdrawal of the riparian forest, which is essential to the balance and maintenance of the ecosystem. Before that, the present work aimed at mapping the environmentally vulnerable areas in the basin of a tributary of the Corumbataí river, located in the district Santa Olímpia, in the city of Piracicaba-SP. For the purpose, techniques were used in Geoprocessing, aiming to produce thematic maps of Slope, for the Use and Occupation of Land, of Permanent Preservation Areas (APP), Soil and Geological of the basin of interest. From these mappings, the analysis was performed multi-criteria, which resulted in the Map of Environmental Vulnerability. This mapping environmental assessment of the study area, indicating proposals of practices for the management and conservation of soil and water resources, for the purpose of improving the environmental quality of the analyzed area. In this way, the research of this nature, may help in the decision-making on the part of the governmental bodies as well as civil society

The Atlantic Forest is considered the fifth most important hotspot of the world, for its high endemism and biodiversity. The Serra do Mar State Park (SMSP) is the biggest area of integral protection in Brazilian coast, having the largest continuous remnant area of Atlantic Forest. Its creation aims to protect the Atlantic Forest remnants and regeneration of degraded areas. The present work develops in the administrative center Núcleo Santa Virgínia, created on May 2, 1989 and aims a comparative analysis and environmental interpretation regarding the evolution of the landscape its creation until the present days, using geoprocessing techniques. For a better understanding of some definitions, a literature review is presented about the current scenario of conservation units, concepts of landscape, landscape ecology, landscape dynamics and the importance of the geoprocessing for landscape analysis. It was elaborated two thematic charts of use and occupation land of Núcleo Santa Virgínia (1989 and 2014) and quantified for each type of use for later comparison
