What is INSPIRE?
• INfrastructure for SPatial InfoRmation in Europe
• A framework directive of the European Parliament and of
the Council of 14 March 2007 (Directive 2007/2/EC) on the
establishment of such a Spatial Data Infrastructure (SDI)

INSPIRE is about improving
access
to and sharing of spatial
information:
Distributed infrastructure: INSPIRE is to be based on the
infrastructures for spatial information established and operated by the
Member States
Organisational and technical harmonisation
Data held by or on behalf of public authorities (including Statistical
Offices)
Data falling under the themes listed in the Directive
For Community environmental policies and policies or activities which
may have an impact on the environment.
The environment doesn’t stop at borders

INSPIRE principles
• Data should be collected once and maintained at the
level where this can be done most effectively
• It should be possible to combine seamless spatial
information from different sources across Europe and
share it between many users and application
• It should be easy to discover which geographic
information is available and under which conditions it
can be acquired and used
• Geographic data should become easy to understand
and interpret
11
12
INSPIRE non- principles
• No requirement to create new spatial data
• No obligation to provide data for free
• No minimum level of quality
• No regulation of scales
12
13
INSPIRE history and future
• 2007 Adoption of INSPIRE directive
• 2008 First implementing regulation on Metadata
• 2009 – 2013 Further Implementing legal acts
• Since 2007 Transposition into national law
• Since 2011 INSPIRE geoportal
• Until 2020 Implementation phase in Member States

Essence of INSPIRE – spatial information
1. Metadata
2. Spatial data sets
3. Spatial data services
15
16
Spatial information under INSPIRE
Data: data from different sources is comparable
Annex I, Annex II, Annex III (3 lists of spatial data themes)
Network services (machine to machine communication)
Discovery service: to be able to find the data in distributed catalogues
View service: to evaluate the data visually
Download service: to actually get the data
Transformation service: coordinate transformation
Invoke service
Metadata
Content: fixed list of elements
Format: to treat it automatically (catalogues, search engines)

How can a user find and use spatial data
under INSPIRE?
•
•
•
•
Geoportals as entry points
Metadata as content description
View services for content evaluation
Download and transformation services for obtaining data in the right
format
=> publish – find - bind

Why metadata and what is special about spatial
metadata
•
•
•
•
•
•
Metadata are data about data
•
INSPIRE metadata are for discovery, some elements on access and
fitness for use
•
Metadata are relevant for data users (find) and for data producers
(publish)
Metadata are essential for finding and understanding data
We distinguish between structural metadata and descriptive metadata
SDMX for statistics covers both
INSPIRE metadata for spatial data are descriptive metadata
Metadata serve different purposes (data discovery, assessing fitness for
use, data access, data transfer, use)
30
32
Metadata for spatial information
• Metadata are structured in hierarchical packages
32
33
Metadata are usually encoded in XML (ISO standard 19139)
33
34
Search for data – how does it work?
• INSPIRE queryables in the Metadata – e.g. title, abstract,
resource type, keywords, topic category
• Search engines in Geoportals
• Thematic search and spatial search

Tour of the INSPIRE geoportal
http://inspire.jrc.ec.europa.eu/index.cfm
•Exercise 1: Search for all resources from your
country, refine it to datasets, then services, then refine
it to hydrography.
•Exercise 2: Go to one resource and read the
metadata. Does it help you to understand the
dataset?
•Exercise 3: Try to find a dataset with a related view
service.
•Exercise
4: Try to add a view service to the map
window on the left and change its transparency.

INSPIRE metadata
• INSPIRE metadata are regulated in „COMMISSION
REGULATION (EC) No 1205/2008 of 3 December 2008
implementing Directive 2007/2/EC of the European
Parliament and of the Council as regards metadata”
• Contains in total 21 metadata elements (19 for data sets
and 17 for spatial data services)
• Further implementation details in INSPIRE Metadata
Implementing Rules: Technical Guidelines based on EN
ISO 19115 and EN ISO 19119 (Version 1.2)
39

Obligations in Member States regarding
INPIRE Metadata
• 03-Dec-2010 Metadata available for spatial data sets and
services corresponding to Annex I and II
• 09-Nov-2011 Discovery and view services operational
• 03-Dec-2013 Metadata available for spatial data sets and
services corresponding to Annex III

Problems with metadata
• Nobody likes to create metadata
• Structure well defined, content not
• Semantic interoperability not enforced
• Unclear titles
• Empty abstracts or other fields
43
44
Tools for metadata work
• Metadata editor
http://inspire-geoportal.ec.europa.eu/editor/
• Metadata validator
•
http://inspire-geoportal.ec.europa.eu/validator/
44
45
Exercise
• Create Metadata using the Internet editor for the map you
have created this morning
45
46
Recommendations on metadata
• Rather write too much than too little.
• Make the title speak for the full dataset.
• Begin the abstract with a short summary paragraph which is
often shown in a geoportal.
• Include in the abstract some information on the main
attributes, the data sources and references to legal acts.
• In the lineage field carefully document the way the data
have been produced.
46
47
An outlook: data models, network
services and transformations
• The INSPIRE data specifications prescribe a specific data
structure.
• This should help users to immediately understand the data
• INSPIRE does not require the creation of new data ->
Transformation of existing data into the INSPIRE format will
be common practice.
