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.

14

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
