摘要：The world of Geographic Information (GI) Science has changed. Today, many of the elements of Digital Earth, meaning as a multi- resolution, three-dimensional representation of the planet, are not only available but also used daily by hundreds of millions of people worldwide thanks to innovative ways to organize and present the data and rapid technological advancements. 3D Geobrowsers can provide higher usability and interactivity that can facilitate exchange and dissemination of spatial information among stakeholders and government agencies. However providing access to harmonized data is only a first step towards providing adequate support to environmental management, which requires development of analysis and spatio-temporal data models functionalities. Many environmental analyses, e.g. monitoring a sequence of earthquakes epicentres, a storm, a forest fire, spread of pollutant etc., cannot be performed without considering the evolution, over time, of geographic features. Additionally today's sensing technologies provide frequently updated GI, at relatively reduced costs, coming from environmental sensors, satellite etc. This forces the GI community to reconsider current data models, taking into account time as one of the main variables. BRISEIDE - BRIdging SErvices, Information and Data for Europe is a Pilot B, funded by the ICT Policy Support Programme (or ICT P SP), tries to bridge the aforementioned gap, by building on top of existing SDIs in order to provide users with more complete and adequate data and processing tools capable to handle the time dimension. BRISEIDE develops spatial analysis WP Ss and integrates them within existing open source frameworks. Spatio-temporal processing services are exposed via the web and are made available through compatible WebGIS applications. Open Geospatial Consortium Web Services, already made available by relevant INSPIRE-related EU projects, exposing standard services such as WMS, WCS and WFS, can be used to provide access to relevant geodatabases, enriched, when needed, with information, extracted from heterogeneous, distributed user operational databases. In addition to this, in order to achieve optimality geo-processing functionalities distribution, standardized services capable to extract data of interest can be provided to ensure spatio- temporal information ingestion, querying, processing, visualization and value added processing. Spatial analysis and Spatio-temporal web processing services (WPS) are exposed via the web and are made available integrating them within existing open source frameworks through compatible WebGIS applications
