Neste artigo é apresentado um Sistema de Apoio à Decisão Espacial (SADE) onde os decisores podem facilmente definir diferentes tipos de problemas espaciais recorrendo a diferentes categorias de objetos, pré-definidas ou a definir, associando- lhes características com ou sem dependência espacial, e indicando formas de interferência (impactos) entre essas caracte- rísticas/propriedades. A análise espacial para determinação ou avaliação de configurações alternativas para a localização de diferentes tipos de ocorrências espaciais será feita através da utilização interativa do SADE de acordo com conjuntos de regras intrínsecas aos vários elementos gráficos (objetos, categorias, características, impactos) utilizados na definição dos problemas. O teste à generalidade representativa e analítica do SADE proposto é efectuado recorrendo a um problema concreto, suficientemente específico e complexo, relativo à aplicação de modelos gaussianos para o estudo da dispersão atmosférica de eventuais poluentes resultantes do tratamento de resíduos sólidos. A região em estudo está limitada, neste exemplo, ao município de Coimbra, Portugal. Para este município estão acessíveis, e são utilizados, os dados demográficos ao nível da secção de voto (censos oficiais) e, como tal, é possível a realização de um estudo realístico do impacto com populações humanas.
In this work a Spatial Decision Support System (SDSS) is presented, where decision makers can easily define different types of spatial problems, resorting to different object categories, pre-defined or to be defined, associating to them space dependent and non-dependent charecterisitics, and indicating forms of interference (impact) between those characteristics/properties. The spatial analysis for determining or evaluating alternative configurations for the location of different types of spatial occurrences is done interactively through the SDSS, according to sets of rules intrinsic to the various graphical elements (objects, categories, characteristics, impacts) used in the problems definitions. The representative and analytical generality of the SDSS is tested in a case study, which is specific and complex enough, relating to the application of gaussian air dispersion models to pollutants resulting from solid waste treatment. The study region of the case study is the municipality of Coimbra, Portugal. For this municipality, demographical data at the ward voting section level (official census data) were available and used. As such, a realistic study of the impact on human populations is possible.
