Goal and Mission
To Supply
Geo-Information and- Application Services
via the Internet as
Integrated and Embedded
part of any websites.Through
Fixed and Mobile connections
these Services can be delivered
any Time, any Place and for Everybody.
The GeoPortal Solution
• From concept to Solution
• Using webservices technics
• 3 Solution businessmodels:– Traditional project;– Outsourcing model;– ASP-model.

GeoPortal, Characteristics
• Data en services at the source
• Distributed environment
• (Mobile) Internet as communication medium
• OpenGIS as standard

GeoPortal remarks
• Moving very fast towards a distributed geo service concept
• GeoPortals:– Data is no longer ‘local’– Geo Processing Resources (services) at a distance
• Commerce will dominate the market?
• Problem: – how to integrate information from different ‘Portals’– Domination of sofware vendors? open standards
• OpenGIS can help us!– Webmapping– Catalog services

AST vision
• The architecture envisioned by AST deploys interoperable services that will help to produce and publish, find and access, and eventually, use and understand geographic information over the internet across the European Union and Accession Countries at local, national, and European levels.
Methodology
• Organisation model - shows the organisation’s goals, relationships (financial, economic, business) between public and private sector, and rules and policies
• User model - identifies the types of users and defines user requirements
• Process model - defines the abstract business objects that will be modelled and codified in the SDI system, their rules, and workflow
• Architecture model - defines the SDI system components and the relationship between them (e.g., servers, their functionality, client applications, etc.) as well as their relationship to the different national and international standards and specifications (e.g. OpenGIS and ISO)
• Implementation model - breaks down the architecture model into smaller components and defines the scope of the technology decisions, deployment platforms, building and reusing components, and performance and networking decisions

Inspire inspired NCGI to change
NCGI History
• Phase 0: Ravi Initiative march 1995
• Phase 1: Idefix - pilot mid 1997
• Phase 2: NCGI official start early 1998
• Phase 3: NCGI version 1.1 end 2000– Redesign website– Pilot WebMapping– Distributed information (nodes at the source)
• Status report early 2001– 13 data suppliers with approx. 1500 geodatasets– Many technical and organizational problems encountered– Financial future uncertain (governmental grant only 4 years)
Motivation for the continuation of NCGI
• Infrastructuur NCGI is OK -> ready for use
• In future focus on exploitation of the infrastructure and on users
• Quality and transparency via NCGI garanteed:– Openess, uses available standards, Security issues,…
• G-to-G discussion within government
• G-to-P discussion ‘not in my backyard’
• International geo-issues:– High water, industrial air pollution, mouth disease,……– New Inspiration from GSDI, GINIE, INSPIRE initiatives
• HOW to continue ???
Public Private Partnership NCGI – Geodan (phase 4)
• Agreement signed end June 2001
• Starting 1 July 2001: – NCGI Foundation remains owner– Geodan responsible for exploitation and maintenance
• Main task of the Foundation: – Watching over, and Monitoring, the mission and goals of the
foundation
• PPP construction used frequently in Netherlands– GBKN : Large Scale BaseMap– IntWIS : Integral Water Information System– KLIC : Cable and Pipe Information Centre (call before you dig)– Sherpa : GeoIT fundament for Nationwide security (homeland)

Mission and Goal: NCGI New Generation
• Mission NCGI:– The NCGI aims at the exploitation and maintenance of an geo-
platform for quick and cost effective publishing and using geo-datasets and geo-infrastructure services for the purpose dissimination of geo-information within and between state, regional and local government and to the general public.
• Goal NCGI:– To run a economic profitable NCGI infrastructure within the
boundaries of the mission. The infrastructure may be used to supply (meta)datasets or may be used for a quick start for projects with high priority or can be used to publish ongoing thematic geo-related information to the public and/or government.
Enough new challenges !!

From basic infrastructure -> end user apps
• Catalog services (metadata) -> Data services
• Data services -> Information services – Focused on theme’s and projects
• Information services -> Knowledge
• Change NCGI from metadata provider -> “service provider”
• NCGI: grow model -> 2002 –2004
In General:
• From GeoDatasets to GeoServices (OWS)

Conditions for NCGI success (challenges)
• User driven NOT supplier/technology driven• Maintain neutrality as PPP
• Expanding from catalog Geoservices provider
• NCGI funding through realisation of projects/theme’s: portal owners
• Motivate data owners to publish geodata (at a fair charge)
• Consequent use of (inter)national standards
• Connect NCGI to closed governmental information networks:– Gemnet, KING, RYX en Waterring, ON2000,…
• Consequent implementation using grow model (2002-2004)– Step by Step
• Follow and adapt International Initiatives OGC, GSDI, INSPIRE• Pricing models
• User driven NOT supplier/technology driven
