Resumo: The use of decision suport tools in Geographic Information Systems (GIS) has assisted in applications areas such as impact, suitability and viability analysis. This work presents an example of the application of these tools for the analysis of gas pipeline pathway connecting a refinery to three cities in the region of Campinas, São Paulo State. Land use and digital elevation model (DEM) were used as variables. The processing and analysis of spatial information were done using GIS IDRISI. The first approach used a cost surface to determine the least cost route. The pathway obtained considered in the majority areas of pastures and with slope of up to 15%. The second approach was based on multiple criteria analysis balancing factors such as distance, slope and land use. The multiple criteria analysis was influenced by land use; however, the slope and the distance between the cities are the basic factors in tracing the pathway, reflecting the lowest cost. This result constitutes an important subsidy for decisions on the best alternative for gas pipeline pathway, allowing a more rational and less subjective choice.

Este trabalho apresenta um exemplo de aplicação dessas ferramentas para análise de trajeto de um gasoduto interligando uma refinaria a três cidades na região de Campinas, Estado de São Paulo. Como variáveis foram utilizadas as informações contidas em um mapa de uso do solo e um modelo digital do terreno (MDT). O processamento e a análise das informações espaciais foram realizados por meio do SIG IDRISI. Na primeira abordagem usam-se superfícies de custo para determinar o melhor trajeto. O trajeto obtido considerou os valores de menores custos, na maioria áreas de pastagens e com declividade de até 15%. A segunda abordagem baseou-se no método de múltiplos critérios com a ponderação dos fatores distância, declividade e uso do solo. A análise por múltiplos critérios foi bastante influenciada pelo uso do solo. Porém, a declividade e a distância entre as cidades são fatores fundamentais no traçado do gasoduto, pois reflete o menor custo. O trabalho constituiu um subsídio importante para a tomada de decisão sobre a melhor alternativa de traçado do gasoduto, possibilitando uma escolha mais racional e menos subjetiva.Universidade Estadual De Maringá2010-07-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontomada de decisãoapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/113310.4025/actascitechnol.v32i2.1133Acta Scientiarum.
