3. GEO 2006 Work Plan Task with active OGC participation
"Facilitate interoperability among Digital Elevation Model (DEM) data sets with the goal of producing a global, coordinated and integrated DEM".
(1) Request input from system operators and data users  (GEO members or participating organizations)  regarding their experience on interoperability
(2) Compile list of current DEM data and its specifications.
(3) Based on the above results, develop the first "GEOSS Interoperability Guidance on DEM data”
(4) Submit this document for review to the GEO plenary.

7. A Wind Farm Site Selection: Prospecting
Stage 1: Search OGC catalogs for suitable data (WRS) and review discovered maps (WMS/WFS/WCS/CPS/WMC)
Stage 2-1: Browse global wind data, and get some data for further analyses (WCS/CPS)
Stage 2-2: Perform further analyses with animated wind data, and overall site review (WCS/WMS)
Stage 2-3: Categorize the wind speed data, (1) select certain wind speed ranges, and display the results, (2) calculate the area of candidate sites (i.e., contiguous cells), and (3) review the terrain and wind speed data for further analyses (WCS/3D Modeling)
Stage 3: (1) Select candidate wind farm sites with suitable wind speeds, (2) measure the distance between the candidate sites and the nearest man made features such as road (or transmission line) segments, and (3) measure the size of candidate sites (WFS/WMS).

8. GEOSS Beijing Workshop: Movie

9. Lessons Learned and Future Works (1)
Tremendous enthusiasm and commitment of agencies and research groups to collaborate – we must continue to tap into this energy.
Demonstrator development effort modest in context of what was achieved but there are areas where implementations of the standards are not interoperable and where better (and easier) procedures need to be put into place. (e.g. catalogs, WCS requests, etc.)
The demonstration provided a fast-track to skills development and knowledge transfer.
The GEOSS applications specific demos are a great way to engage with user communities that would not necessarily look to OGC standards.
The demo also provided a means of creating interest in “new” geographical areas but the follow-up mechanism needs to be in place to secure on-going involvement and membership.

10. Lessons Learned and Future Works (2)
The live demo is “probably” not the best means of communication – it impressed those that already were aware of what OGC was about but for most a more educative approach (simple language, descriptive material) would be better and a management targeted descriptive document should accompany future presentations. [Effort for return, dependency on good comms links].
We need the demo to be “persistent” so that having attracted the interest of people/organisations they can come back to it with colleagues and to achieve greater depth of understanding perhaps by accessing the demonstrator and doing organisation specific add-ons to test capability.

11. Comments from Charlotte Hasager, Wind Energy Community of Practice
Could you send a message with your impressions and comments about the China wind energy demo?
It was very good indeed. First of all, despite the not very fast internet connection, everything was succesfull. This is impressive in itself. Furthermore the content was good. It is clearly a very good option to be further exploited in wind energy. At the same time it is very new as the wind energy industry is based on a lot of other means. In China the aim to use satellite image information and database information for wind resource mapping is higher than anywhere else I have seen what is going on. So it was a very good place to have ths demonstration indeed.
Do you think the demo was effective in explaining the use of distributed web services for the wind energy societal benefit area?
It was in fact excellent. It is clear that several additional aspect than wind, land cover and digital elevation data are needed. This is e.g. the distance to grid, urban, snow climate info, etc. So the system of distributed web service is very relevant. It was clearly demonstrated, and more information can be included in future demo' s and practical work.
Was the role of open standards for interoperability between software from various companies?
This was not so clear, as the wind energy companies were not much involved. In fact, my own 'company' which is a govenmental institute, but with permission for sales of software, are selling on type of 'de facto standard' wind resource mapping software. It would take a bit of work to fully integrate from open standard to e.g. this software. If it first is done, it would be easy to use the info also in many other wind engineering softwares as there is relative open link between them. For our software, the full information on formats is available on the internet.
How was the demo received in Beijing?
It was received very well. Many very interested wind energy people in China attended the meeting, and I feel sure we all were impressed with t he demo. Wind energy (renewable energy as a whole) is very fast in progress in China, and the wish to learn out there is very high.
