Goal of the project

• Development of the GI based information system for the 48 IHLET Office’s.
• Pilot project is ready.
• Possibilities of neutral information technologies in one multinational information system.
• Design of an objective data capturing and management system.
• Management of the datasets on the local level.
• Support of the NSDI, ESDI (metadata, INSPIRE).
• The project objectives are relevant for accessing various kinds of EU Funds.
• National GI Infrastructure is being strengthened in the region.
• Focus is on regional scale and adding value.
• Tools and GI information are becoming more common.
• Synergy with others is a key condition.
• Addresses the needs of the socially excluded.

Architecture:

• The GI infrastructure will be managed on three levels.
• Centre - Tisza River Basin Region level.
• Node Points - National.
• 48 Local Offices - Association at NUTS4 level.
• The pilot GI system is able to manage the datasets in the three levels.
• The solution is based on server-client applications.
• The capture and update of the local datasets is on the local level.
• The Region and National level is in the centre.

Database:

• Pilot datasets
• Store the GI and alfanumerical datasets
• Shared databases
• Based on SQL server technology
• GI datasets
• Spatial indexed datasets -> PostgreSQL (PostGIS)
• Alfanumerical datasets
• PostgreSQL
• Centre - Tisza River Basin Region level
• Aggregated and generalized data
• Data to cover gaps of the national GI infrastructure
• Added subjects: environmental, economic, social
• Meta data
• Node Points - National
• Aggregated and generalized data
• Access to relevant national level thematic maps
• 48 Local Offices - Association at NUTS4 level
• Local large scale data: cadastre, utilities, urban planning, etc

Database - GI:

• Pilot GI datasets
• PostgreSQL -> PostGIS datasets
• Vector data into spatial indexed database tables
• Relations between the databases on the different levels
• GI possibilities based on the PostgreSQL - PostGIS technology (use of different coordination systems)
• GI analysis with the PostGIS functions
• Social analysis
• Environmental analysis
• Economic analysis



• NUTS levels
• Place of the Roma population
• Network of the settlements
• Road network
• Results of the applications

• Possibilities
• Digital elevation model
• Orthophotos
• Cadastre maps
• Environmental datasets
• Economical datasets
• WMS services
• SOAP based datasets
• Aggregated and generalized data

Database - Social Data:

• Alfanumerical datasets (Roma population area)
• NUTS levels



• Local administration information
• Public services
• Water
• Electricity
• Gas
• Roads
• Type of buildings
• Garbage collectors
• Population

Solution:

• Web Application
• Web Services to use the local datasets

  

  • SOAP protocol
  • WSDL
  • UDDI
• Neutral data management with XML documents
• Connection between applications
• OGC standards
  • GML
  • WMS
  • WFS
  • WCS
• OpenGIS® Web Map Service
• OpenGIS® Web Feature Service
• OpenGIS® Web Coverage Service
• Metadata standard (2008 INSPIRE)
• XML – GML based applications
• GI dataset integrations with Web Services
• Conversion between XML documents

  

• Webserver
  • Publishing
  • Web content
• Application server
  • Business logic
  • Communication with the server machines
  • Support of the Web Services
  • Administration of the database
• Mapserver
  • Publication of GI datasets
  • Communication with mapservers (WMS, WCS, WFS)
• Database Management System
• Store of the GI datasets
• Alfanumerical

Security:

• Security of web applications
• Database security (DBMS)
• User definitions
• Web application user grants
• https protocol
• CA (Certificate Authority) -> web certificates

Connection:

• Multilingual user interface
• Multilingual database tables
• UCS (Universal Character Set), the ISO-10646 standard
• UTF-8 encoding
• UNICODE documents
• Support of national character sets
• Support in the GI datasets (PostgreSQL support)
• Support in the Web applications
• XML support

Conclusion:

• Support of the Ihlet Program and Ihlet Offices
• Centre - Tisza River Basin Region level
• Node Points - National
• 48 Local Offices - Association at NUTS4 level
• Possible connection with the EU Fund, local government and land government with the open standards and IT technologies
• GI based information system
• Support of the NSDI, ESDI
• Support of the national INSPIRE infrastructures
• Standards
• OGC (GML, WMS, WFS, WCS)
• W3C (Web Services)
• ISO (OGC, Metadata)
• INSPIRE
