Uma abordagem para modelar fenômenos espaço-temporais.

Abstract

Conceptual models and frameworks have been used widely in several areas of geographic application. Although these models and frameworks are expressive, it was verified that a few them include the modeling of phenomena appearing based in originals spatial fields and/or based in others phenomena (recursive form). These phenomena need appropriated primitives for representation of their spatio-temporal rules and restrictions that describes phenomena origins and development. So, Professor Nectaria Tryfona proposed a specific framework to model phenomena with the use of spatial, temporal and spatiotemporal caracteristics. This dissertation presents an extension of Tryfona’s framework improving the modeling temporal aspects, including recursive phenomena and supporting phenomena appearance and progression in environmental applications. Besides, it presents an concrete implementation. The implementation was developed to control risk areas of land slipping in Recife city, that include topography, geology, environment occupation factors and, mainly, the phenomena of rains and storms. In relation to temporal aspects, new classes and pictograms presented in Luciana Vargas da Rocha’s dissertation were incorporated in the extended framework. Therefore, this dissertatation presents a new model of environment applications that embrace the use of spatio-temporal phenomena, with the intention to give greater facility in a complex theme (Modeling Phenomena). On the other hand, the realized implementation could become a tool to support cities’ administrator in the decision making of environmental catastrophe control.
