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 accessto spatial information:

The environment doesn’t stop at borders

Distributed infrastructure: INSPIRE is to be based on the infrastructures for spatial information established and operated by the Member States

Organisational and technical harmonisationData held by or on behalf of public authorities (including Statistical

Offices)Data falling under the themes listed in the DirectiveFor Community environmental policies and policies or activities which

may have an impact on the environment.

A little INSPIRE history

• 2007 Adoption of INSPIRE directive

• 2008 First implementing rule on Metadata

• 2009 – 2013 Further Implementing Rules

• Since 2007 Transposition into national law

• Since 2011 INSPIRE geoportal

• Until 2020 Implementation phase in Member States

12

12

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

13

13

INSPIRE non-principles

• No requirement to create new spatial information

• No obligation to provide data for free

• No minimum level of quality

14

14

INSPIRE Legislation

• INSPIRE Directive – a framework directive

• Transposition into national legislation

• Detailed technical definition in Implementing Rules (Regulations)

• Implementing rules on Metadata, Network Services, Interoperability, Monitoring and Reporting and Data Sharing

• In addition non bindingTechnical Guidancedocuments

Scope of INSPIRE

Metadata

Content: fixed list of elements

Format: to treat it automatically (catalogues, search engines)

Data specifications: data from different sources is comparable

Annex I, Annex II, Annex III (3 lists of spatial data themes)

Network services (machine to machine communication)

Discover 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

Block 2 INSPIRE Metadata

21

21

Metadata

• Metadata are data about 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)

• INSPIRE metadata are for discovery, some elements on access and fitness for use

• Within the publish-find-bind pattern of a service oriented archtitecture MD are essential

• Metadata for data users (find) and for data producers (publish)

22

22

Metadata for spatial information

• EN ISO standards for metadata on spatial data (ISO 19 115) and on spatial services (ISO 19 119)

• Lists almost 300 possible metadata elements

• MD elements can be mandatory, optional or conditional

• Contain a core profile mainly for use in catalogue services

• ISO core the starting point for INSPIRE metadata

• For specific communities profiles are recommended (selection of metadata elements in addtion to

23

23

Metadata for spatial information

• Metadata are structured in packages

24

24

Metadata are usually encoded in XML (ISO standard 19139)

25

25

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)

26

26

Obligations in Member States regarding 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

30

30

Tools for metadata work

• Metadata editor

http://inspire-geoportal.ec.europa.eu/editor/

• Metadata validator• http://inspire-geoportal.ec.europa.eu/validator/

31

31

Exercise

• Create Metadata on NUTS 2006

• Download the exercise sheet from the EFGS website

•http://www.efgs.info/projects/estp-2012/modul-a05-inspire/A05_Petri.ppt/view

32

32

Recommendations

• 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.

• Put into the abstract information on the main attributes, the data sources and references to legal acts.

• Some information could be redundant (geographic coverage, dates) but help the user

• In the lineage field carefully document the way the data have been produced.

INSPIRE not only for geographers – data themes with direct relevance for statistics

Annex II•Elevation•Land cover•Orthoimagery•Geology

Annex III•Statistical units•Buildings•Soil•Land use•Human health and safety•Utilities and government service •Environmental monitoring facilities•Production and industrial facilities•Agricultural and aquaculture facilities•Population distribution - demography

•Area management/restriction/ regulation zones & reporting units

•Natural risk zones•Atmospheric conditions•Meteorological geographical features

•Oceanographic geographical features

•Sea regions•Bio-geographical regions•Habitats and biotopes•Species distribution•Energy resources•Mineral resources

Annex I•Coordinate reference systems •Geographical grid systems•Geographical names•Administrative units•Addresses•Cadastral parcels•Transport networks•Hydrography •Protected sites

35

35

Data models 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 data into the INSPIRE format will be common practice.

Block 4 Geoportals

38

38

How to search for dataPublish – Find - Bind

39

39

Search for data

• INSPIRE queryables in the Metadata – e.g. title, abstract, resource type, keywords, topic category

• Thematic search and spatial search

40

40

Tour of the INSPIRE geoportal

•Exercise I: Search for all datasets on Hydrography with English metadata in Luxembourg

•Exercise II: Add 2 View services from the same area on top of each other and change the transparency of the top one.
