AB: Virtual Observatories [VO's] hold the promise of providing streamlined access to disparate, heterogeneous data concerning a particular area of study, enabling researchers, educators, decision makers and the public to find and use more of the information they need. In the context of the study of a river basin, the task of building a VO requires the connection and integration of existing data from multiple scientific disciplines and multiple data providers. A prototype VO is being assembled which allows users to locate and access extensive data related to the Illinois River and the environmental issues relevant to its basin. The key steps in this project include 1) discovering and accessing the relevant datasets, 2) producing standard metadata to describe the datasets, and 3) integrating the data sources and datasets using a cyberinfrastructure that is compatible with emerging international standards for data interoperability (ISO geospatial metadata, CUAHSI HIS, GIS data formats). This prototype project tests the capability of the CUAHSI Hydrologic Information System [HIS] to provide the basic data infrastructure for a local river basin observatory and connect that infrastructure with the community at large. The Virtual Observatory applies the local knowledge necessary to build a comprehensive VO relevant to the indigenous issues of the Illinois River, while working to make this data accessible using standards for cyberinfrastructure interoperability. Lessons learned during the assembly of this VO are presented, as well as recent developments of the CUAHSI Hydrologic Information System.
