GEOSS Architecture Implementation Pilot-II: Integrating Technologies and Expertise to Build GEOSS


There are numerous, distributed Earth observations that are in principle available and useful for societal benefit applications such as analysis of air quality events or renewable energy. Currently, Earth observation providers face challenges efficiently disseminating data to users in needed formats. Data users also face hurdles in finding, accessing, and using the right Earth observations for their needs. GEOSS is designed to reduce the burden on both the provider and the user, by providing easier data discovery and access to distributed resources through standard protocols and open architecture. The GEOSS Architecture Implementation Pilot-II (AIP-II) was organized with workgroups for societal benefit areas (SBAs) and transverse technologies (TTs). The SBA workgroups used their domain expertise to test end-to-end flow of data and metadata from data providers to data users with specific application needs. GEOSS mandates that metadata and data are registered using standard protocols such as WMS and WCS for data access and ISO 19115 and 19119 for metadata. These standards allowed the data being registered in community catalogs to be findable in the GEOSS Clearinghouse and automatically accessible through WMS viewers and other tools. The TT workgroups tied the diverse SBAs together by helping the SBAs implement standards for data access and metadata and develop common tools and methods that could be used by the SBAs. The TT workgroups laid out a set of use cases which provide a framework for different groups to add components that aided the end-to-end flow of data to the user. Collaboratively, the workgroups implemented the use cases and developed and refined the processes of deploying, documenting, and registering data through the GEOSS Common Infrastructure (GCI) for use in societal benefit area applications. The SBA and TT workgroups were connected through weekly discussions, and the work was captured using an online collaborative workspace. This allowed SBA workgroups to be aware of each other's work, allowed the transverse technology work groups to provide resources for each use case step, and exposed issues with implementation of a particular standard or process in the GCI. The completion of AIP-II resulted in data access services being found and accessed through the GCI by users. However, this is just the first step and a focus for the next phase of AIP is for scientists and other end-users to use data available through GEOSS for scientific exploration and understanding.
