INSPIRE Directive draws up that
Member states should provide descriptions of spatial datasets and services within the scope of the
National SDI's and shall establish and operate a network of the services for the spatial data sets and services for which metadata have been created.
To ensure that the spatial data infrastructures of the Member states are compatible and usable in a global and trans-boundary context, the Directive requires that Implementing
Rules (IR) about
Network Services were adopted and implemented for the web services available.
One of them in the "discovery service" that allows users and computer programs the searching of spatial datasets and services based on their metadata.
Taking into account the principles of INSPIRE Directive about services, and due to the necessity to ensure that INSPIRE
Discovery Services were implemented in a consistent and compatible way across
Europe, in
2011, the
National Geographic Institute of
Spain (
IGN), had taken the initiative of creating the INSPIRE discovery service and a catalogue client that gives support to data and service metadata of the resources of the
Spanish National SDI.
The service called IDEE-CSW INSPIRE, is a discovery service that allows search and retrieval of descriptive information (metadata) about data and services and meets the INSPIRE
Profile of
OGC™
Catalogue Service Specification 2.0.2 -
ISO Metadata Application Profile for
CSW 2.0 (CSW ISO AP), the Technical
Guidance for the implementation of INSPIRE Discovery Services and the rules of procedure defined by
Initial Operating Capability Task Force. This service has been built using a free software application (Geonetwork 2.
6.4).
IGN Spain had created a web catalogue service (
http://www.ign.es/csw-inspire) where the user can find descriptive information (metadata) of the series, units,
Digital Terrain Models, Topographic Databases, Orthoimages, Web Map Services, and other
Inspire services so on and if after consulting the information
. If the user is interested in getting these products, he can access data through the CNIG
Download Center or the set of downloading web sites described in http://www.idee.es/resources/CentrosDescarga/Organizaciones
.html.
The cartographic products shown in the catalogue are classified as Dataset, series and
Web Services according to the hierarchical levels defined in
ISO 19115.
Nowadays, there are a lot of CSW services and clients, OGC compliant, that integrates through the
Internet metadata of data and services, within the
State,
Regional and
Local government levels, but there are a very few examples of Inspire compliant Discovery Services and clients.
Therefore, IGN Spain, has contributed to create an actual example of implementation that can be a meeting
point for experts dedicated to the cataloguing of geographic information, with the objective of stimulating the development of discovery services and therefore, to help the development of Spatial
Data Infrastructures.
The client developed is embbebed in the Spanish
Spatial Data Infrastructure Geoportal, www.idee.es, a collective project based on the cooperation of a large number of actors in Spain: governmental bodies at national, regional and local levels, private companies, universities, citizens, to offer a wide range of resources related with Geographic
Information. Its spirit is based on cooperation and openness through their consensus and experiences according to INSPIRE guidelines,
Open Geospatial Consortium (OGC) interoperability specifications and ISO 19100 standards.
The aim of this paper is present this service and the client in order to assist in the process of creation and development in a community, to explain its main characteristics and the future steps of development.
Lessons learnt, problems found, difficulties and pitfalls are summarized in a set of conclusions.
