Preface to SeCoGIS 2008
Geographical Information Systems are nowadays considered as one of the most challenging and promising areas that might beneficiate from research advances in conceptual and semantic modeling. It has been largely recognised that the integration of semantic and conceptual models within Geographical Information Systems will help to develop innovative solutions for the benefits of urban and environmental applications. This is very much the objective of the SeCo- GIS workshop that serves as an integrated forum for disseminating research and experience in conceptual and semantics issues associated to Geographical Information Systems. It brought together leading researchers and developers to discuss the state of the art, and to understand novel challenges and emerging research directions.
