INSPIRE Conference 2010 INSPIRE as a Framework for Cooperation Network Services for Spatial Data in European Geo-Portals and their Compliance with ISO and OGC Standards Elżbieta Bielecka Agnieszka Zwirowicz Dariusz Dukaczewski Instytut Geodezji i Kartografii Krakow, 23-25 June 2010
THE AIM OF THE STUDY Analyses the current state of play of national geo-portals development and their compliance with ISO and OGC standards.
METHODOLOGY (1) Ex post evaluation, based on data collected through web survey at the beginning of 2010. Analysis from the point of view of end-user. No investigation has been made on geoportal with limited access to unregistered user.
METHODOLOGY (2) European geo-portals were analyzed in terms of: visibility of map viewer, the number of language versions of view services, the functionality of view services, availability of network services like WMS, WFS, CSW, and compatibility with the relevant OGC specifications and ISO standards.
METHODOLOGY (3) Issue Visibility Accessibility Map viewer GUI Discovery services Download services Parameters or measures Link to the map viewer No of language versions Types and No of functions Compliance with INSPIRE OGC WMS standard version Existence of service Compliance with INSPIRE OGC CSW standard version Existence of service Compliance with INSPIRE OGC WFS standard version
(1) 30 of 43 European States do have official national geo-portal, with Denmark, Finland, Slovakia and Switzerland have two or more. Spatial data view service is available in 28 States.

Compliance with INSPIRE and OGC standards Download service ISO/DIS 19142, ISO/DIS 19143, WFS Implementation Specification. Non of the analysed geo-portal offered direct access to download services using Web Feature Service OGC standard.
Compliance with INSPIRE and OGC standards Discovery service ISO 19115, ISO 19138, COMMISSION REGULATION. Metadata are collected in accordance with different standards (e.g. ESRI, NGDF). Out of 14 analyzed catalog services just 2 are compatible with the OpenGIS Catalogue Service Implementation Specification.

European Geo-Portals in Users Opinion
CONCLUSIONS The current geo-portal activities in Europe are mostly driven by the INSPIRE Directive. Each of Member States has started some investments in implementing a national geo-portal. The state of play differs - Some portals have implemented a lot of different functions, even much more than is required by INSPIRE. There is a lack of consistency in naming tools and functions.
CONCLUSIONS Major difficulties in obtaining information about viewing, discovery and downloading services were: the language barrier, the discrepancy between information set out in the description of services (including information available in on-line help) and information available directly through the service interface, high dynamic of geo-portals functionality.
