The document discusses the design of a relational database system called the Supersite Relational Data System (SRDS) that would integrate air quality monitoring data from multiple Supersite projects and auxiliary datasets for cross-site analysis. It proposes using a star schema with dimensions for time, location, parameter, and method to facilitate querying and comparisons across different monitoring sites and projects. The schema would be extended as needed based on user requirements and consensus-building within the Supersite working groups.

17. Federated Data Warehouse Architecture XML Web Services HTTP Services Time Chart Scatter Chart Text, Table Data View & Process Tier Layered Map Cursor OpenGIS Services Data are rendered by linked Data Views (map, time, text) Distributed data of multiple types (spatial, temporal text ) The Broker handles the views, connections, data access, cursor Satellite Vector GIS Data XDim Data OLAP Cube SQL Table Text Data Web Page Text Data Data Warehouse Tier Data View Manager Connection Manager Data Access Manager Cursor-Query Manager

18. Example Data Viewer (to be made more Supersite relevant) Map View Variable View Time View WebCamView The views are linked so that making a change in one view, such as selecting a different location in the map view, updates the other views.

34. Integration for Global-Local Activities Global Activity Local Benefit Global data, tools => Improved local productivity Global data analysis => Spatial context; initial analysis Analysis guidance => Standardized analysis, reporting Local Activity Global Benefit Local data, tools => Improved global productivity Local data analysis => Elucidate, expand initial analysis Identify relevant issues => Responsive, relevant global work Global and local activities are both needed – e.g. ‘think global, act local’ ‘ Global’ and ‘Local’ here refers to relative, not absolute scale

35. Content Integration for Multiple Uses (Reports) Data from multiple measurements are shared by their providers or custodians Data are integrated, filtered, aggregated and fused in the process of analysis Reports use the analysis for Status and Trends; Exposure Assessment; Compliance … The creation of the needed reports requires data sharing and integration from multiple sources.
