2. Contents  Response to the Action Items to the Task Team  Presentations - Task Team FAQ - Task Team Potential Contribution to GEO

3. Task Team FAQ for WGISS website (Q 1) What is “Data Services” Data Services assists users to obtain Earth observation satellite data resources. As a nature of Earth observation data, the data is stored disparately. Therefore, Data Services assists users to obtain data from distributed systems based on interoperable data serving mechanisms. In a broad sense, to bridge between data users and data resources, Data Services also assists users in obtaining data from heterogeneous and distributed data resources through data integration processes. This can be done by encapsulating data within associated services, for instance. Data Services also covers distribution of information which is derived from data.

4. Task Team FAQ for WGISS website (Q 2) What technical areas are explored in relation with data services In the CEOS/WGISS Data Services Task Team (DSTT), perhaps the most popular type of service system which has been explored and deployed by various members are data access services such as the WMS (Web Map Service) and WCS (Web Coverage Service) defined by OGC. Also, various technologies related to data, services, and WWW related technologies are being explored by members, such as the SOA – xml web services, semantic based technology, ISO 19119 (Services), and Sensor Web Enablement.

5. DSTT contribution to GEO work packets -GEO will develop a collection of accessible service components. -Work Packets consists of two main types. –> “Transverse Area”, “Social Beneficial Area”  GEO  Contribution from DSTT - Will be a good opportunity to provide service infrastructure, such as service catalogue systems DA-06-04 : Data, Metadata, and Product Harmonization DA-06-06 : Spatial Data Infrastructure -Our efforts will be more effective if we focus on transverse area (i.e. in “Architecture” and “Data Management”). -Selected packets :

6. Work Packet : DA-06-04 “ Data, Metadata, and Product Harmonization ” Facilitate the development, availability and harmonization of data, metadata, and products commonly required across diverse societal benefit areas, including base maps, land-cover data sets, and common socio-economic data. Task Title 1.Organize workshops 2. At the workshops, complete an initial version of an inventory of required data, metadata, products, and services commonly required across diverse societal benefit areas 3. Publish a Findings and Recommendations document To be performed:

7. Advocate use of existing Spatial Data Infrastructure components as institutional and technical precedents, where appropriate, including standard protocols and interoperable system interfaces, among other components. Task Title 1.Document baseline as to - needs for basic geographic data societal benefits area - use of existing SDI systems. 2. Establish a process for informing GEO Members and Participating Organizations regarding SDI procedures, meetings and communications. 3. Publish first Report which will identify degree of satisfaction for basic geographic data and the use of and needs for SDI institutions and technical precedents. To be performed: Work Packet : DA-06-06 “ Spatial Data Infrastructures ”

8. - Basic idea for both packets is the same. (1)Offer WGISS operational service infrastructure (- IDN-SERF (of IDN TT) to advertise higher level services description) -ECHO Web Service Registry to advertise description to invoke operations and access to machine. - They are interactive each other via web service method. (2) Provide information to make document - by contributing the TS Subgroup Interoperability Handbook. (3) Other Workshops on these work packets will be a good place to: - Present technological achievements and systems. - Share information on commonly required services.  Contribution from DSTT DSTT contribution to GEO work packets (cont.)

9. Thoughts Regarding Social Benefit Work Packets (1) Each work packet is interrelated, not independent, - There will be commonly required input data. - Outputs of some work packets will become inputs to other work packets. - There might be commonly required services also. (2) GEO may organize the work within the work packets to avoid redundancy, (3) GEO may provide information (to WGISS) on the following items for each work packet: - appropriate input - appropriate output products and information - necessary processes (to create output from input) From the viewpoint of services,

10. (4) WGISS membership includes many EO data providers/distributors. (5) WGISS would be an appropriate organization to develop ideas and methods to leverage wide EO data distribution to a diverse community, especially from data producer’s view point, to bridge data to users via service infrastructures. Thoughts Regarding Social Benefit Work Packets (cont.)

11. - A possible WGISS contribution may include: development of service taxonomies for the various Social Benefit Areas - Service taxonomies will support user friendly service discovery in service catalogues. - Parallel activities on service catalogue development in WGISS: - Testbed / Operational - ICS EO Portal development may provide experience on commonly required services and descriptions of services. -CEOS/WGISS meetings are an opportunity for presenter(s) to get feedback on their ideas on service terminology Other Discussion
