Charvat ppt gi2011_the pyramid or spider network_final

  1. 1. The pyramid or spider GI2011 network – towards social geospatial space in European Border RegionsKarel CHARVAT22.5.2011
  2. 2. SDI GAPS2 GI2011 22.5.2011
  3. 3. The pyramid or spider networkGI2011 22.5.2011
  4. 4. Society and SDI4  Spatial Data Infrastructure is usually taken as sharing data between public organizations.  This situation is usually described as pyramid, where higher level get collect data from lower level  This solution is very weak and makes big concerns about failures of whole system  Cross boarder regions need direct communication and data sharing GI2011 22.5.2011
  5. 5. ExampleCross boarder tourist and transport information system NISA GO GrenzeIntegration of public and voluntary data cross boarderGI2011 22.5.2011
  6. 6. Example NISA GO GrenzeGI2011 22.5.2011
  7. 7. ExampleSimilar examples could be in environment protection, cross boarder risk management, etcNeeds to integrate cross boarder public and private data and use advantage of voluntary initiativesSpatial data has to be integrate on the base of regions, thematic groups (geologist, planners, environmental scientists, etc)GI2011 22.5.2011
  8. 8. 4th way philosophy8  Number of interconnected thematic or regional servers, some of them are available for training (free of charge) or for community data sharing  INSPIRE and GEOSS compatible solution, based mainly on Open Source solution  Interconnection of public and private infrastructures  Support for voluntary initiatives GI2011 22.5.2011
  9. 9. Public-private cooperation9  SDI is important not only for public decision, but it brings benefits for economical activities and also for communities  Current philosophy offers usage of 3 different portal solutions  Public  Commercial  Communitarian We need to move over this assumption. GI2011 22.5.2011
  10. 10. 4th way concept10 GI2011 22.5.2011
  11. 11. 4 important topics for 4th way11 1. To move from applications oriented solution to service oriented architecture (SOA) 2. To build network of interconnected nodes, where every node could be server (supplier) of information or client (receiver) 3. Overcome classical portal paradigm, where portals are final products 4. To be able to build new generation of an application on the base of SDI services GI2011 22.5.2011
  12. 12. 1. From applications to services12  Most of current Web based solutions are applications  This concept doesn’t give possibility to use full advantage of SDI.  Spatial data could be used only in application and it is problem to use them in another application (portal).  Application based system doesn’t allow to build new services. GI2011 22.5.2011
  13. 13. 2. Network of interconnected13 nodes GI2011 22.5.2011
  14. 14. 3. Portal is not final products14  Standard user doesn’t need Geoportal,  Geoportal is framework for experts, allowing them to build solutions for final users  Geoportal is tool, which has to support building of new level of “applications”.  It is important to design methods, which will allow building of service orientated solutions. GI2011 22.5.2011
  15. 15. 4. New generation of15 application  New generation of applications has to fully benefit from SDI  It has to be service based – no data replication, reusage of existing components.  It has to support integration with other systems  It is valuable to support integration with social networks GI2011 22.5.2011
  16. 16. Key problem• Data availability • Data are key problem of any SDI • Till now public accessibility of data are limited in some countries • This is reason of growing interest of commercial providers, but also reason for growing voluntary initiatives• Needs for real building of discovery servicesGI2011 22.5.2011
  17. 17. Where we areTechnology are ready for step 2. From our side it is technology based on concept Geoportal4everybody, but there exist number of other solution offering similar servicesTill now is not general understanding of points 3 and 4.Also technology are till now full ready for thisGI2011 22.5.2011
  18. 18. Important issue for 4th wayEuropean Environmental Agency make most of their spatial data publicly available for commercial and non commercial purposes. There is only necessary give information about copyrightThe problem is, that data are currently not available as services, but only as shapefileGI2011 22.5.2011
  19. 19. Our contribution for 3 and 4Work with WMCPossibilities prepare map iframe, which could be integrated into other web pagesWe started experiments with Liferay as platform for integration of future SDI applicationsFirst step with integration with social mediaSupport for GoogleMap and GoogleEarthGI2011 22.5.2011
  20. 20. What is under developmentSupport for processing services – here is question, if is possibility that processing workflow will be build by users, or it will be task for programmersPublic API for map client to support better integration with external servicesSupport for sensors technologiesGI2011 22.5.2011
  21. 21. Hot newsUrban Atlas is published as WMS and WFS from Geoportal4everybody – so Urban Atlas become now available for all communityPossibility to work with GoogleMaps on Geoportal4everybodyNew release of Geoportal4everybodyGI2011 22.5.2011
