4. Society and SDI
4
 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. Example
Cross boarder tourist and transport information
system NISA GO Grenze
Integration of public and voluntary data cross
boarder
GI2011 22.5.2011

6. Example NISA GO Grenze
GI2011 22.5.2011

7. Example
Similar examples could be in environment
protection, cross boarder risk management,
etc
Needs to integrate cross boarder public and
private data and use advantage of voluntary
initiatives
Spatial data has to be integrate on the base of
regions, thematic groups (geologist, planners,
environmental scientists, etc)
GI2011 22.5.2011

8. 4th way philosophy
8
 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. Public-private cooperation
9
 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. 4th way concept
10
GI2011 22.5.2011

11. 4 important topics for 4th way
11
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. 1. From applications to services
12
 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. 2. Network of interconnected
13
nodes
GI2011 22.5.2011

14. 3. Portal is not final products
14
 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. 4. New generation of
15
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. 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 services
GI2011 22.5.2011

17. Where we are
Technology are ready for step 2. From our side it
is technology based on concept
Geoportal4everybody, but there exist number
of other solution offering similar services
Till now is not general understanding of points 3
and 4.
Also technology are till now full ready for this
GI2011 22.5.2011

18. Important issue for 4th way
European Environmental Agency make most of
their spatial data publicly available for
commercial and non commercial purposes.
There is only necessary give information about
copyright
The problem is, that data are currently not
available as services, but only as shapefile
GI2011 22.5.2011

19. Our contribution for 3 and 4
Work with WMC
Possibilities prepare map iframe, which could be
integrated into other web pages
We started experiments with Liferay as platform
for integration of future SDI applications
First step with integration with social media
Support for GoogleMap and GoogleEarth
GI2011 22.5.2011

20. What is under development
Support for processing services – here is
question, if is possibility that processing
workflow will be build by users, or it will be
task for programmers
Public API for map client to support better
integration with external services
Support for sensors technologies
GI2011 22.5.2011

21. Hot news
Urban Atlas is published as WMS and WFS from
Geoportal4everybody – so Urban Atlas
become now available for all community
Possibility to work with GoogleMaps on
Geoportal4everybody
New release of Geoportal4everybody
