Analysis and management of urban area air pollution spatiotemporal data: case study of Attica

Abstract

The effective management of spatiotemporal data, which relate to urban area air pollution, constitutes a decisive importance stage to the development of a Geographic Information System (GIS), specifically tailored to study and monitor of this phenomenon. The design of the database, for such a system, has particular importance as far as it influences the successful operation of the final system. The modern technologies of Object Oriented Data Modelling in GIS, offer the possibility to design databases taking into consideration the specialised requirements of each application. In this work we present the methodology that was followed and the results that were produced from the design of the database for the Icaros-NET platform which bases its operation on a wealth of geographic data, non-homogeneous, as for the spatial and temporal scale. The design of this database was made using the Unified Modelling Language (UML) and the creation of a data description and exchange with the use of the Extensible Markup Language (XML).
