The pyramid or spider network
22.5.2011GI2011
Society and SDI
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

Example
Cross boarder tourist and transport information
system NISA GO Grenze
Integration of public and voluntary data cross
boarder
22.5.2011GI2011
Example NISA GO Grenze
22.5.2011GI2011
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)

4th way philosophy
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

Public-private cooperation
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.

4th way concept10
22.5.2011GI2011
4 important topics for 4th way
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
11
22.5.2011GI2011
1. From applications to services
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.
12
22.5.2011GI2011
2. Network of interconnected
nodes13
22.5.2011GI2011
3. Portal is not final products
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.

4. New generation of
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

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
22.5.2011GI2011
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
22.5.2011GI2011
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
22.5.2011GI2011
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
22.5.2011GI2011
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
22.5.2011GI2011
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
