The European Location Framework
technical infrastructure which
delivers
authoritative,
interoperable,
cross-border
reference geo-information for
analysing and understanding
information connected to
places and features
28 August, 2013
ONE SOURCE FOR
REFERENCE GEO-INFORMATION

Authoritative
data
… in the sense of turning authoritative reference
geodata into a real European location framework

Why automation of DQ validation?
Change in how geo-information is
produced and consumed
for variety of purposes
broad range of consumers
Multiple sources including VGI
Data models more complex
Reference geo-information needs
quality (authoriative data)
INSPIRE directive of the EU(2007)
Annex I, II
Connecting reference information to
other information
Linked Open Data
Need for provision of cost/time
effective and standardised
framework to measure and
improve quality
Meeting the changed needs
Increase of users’ trust

Data Quality Management
Three approaches
Data Centric ->
evaluating quality
(ISO 19157 and
ESDIN)
Process Centric ->
evaluating capability
(ISO 19158)
User Centric
approach -> creating
trust -> authorative
sources , usability
evaluation -> ELF

Quality reports
28 August, 2013
Reports (Excel) Mark-ups (Shapefiles)
Info Title sheet (with information
about the rules for Hydro)
Comply features that fail the ‘comply’
rule set
Comply summary of the high-level
statistics for
o the whole dataset,
o class by class,
o rule by rule basis.
Aspire features that fail the ‘aspire’
rule set
Aspire Same as above for desirable
‘aspire’
data quality rules
Vertex features that fail the specific
rule for minimum vertex
distance
Profiles set of tables relating to
specific data characteristic
distributions on specific
classes, on the frequency of
values across the data
Xborder
(for Trans)
highlighting where data is not
consistent across state borders

Quality metrics (1)
The “obj Count” column gives the number of features
checked
The “No. Fail” column gives the number of feature that
have failed the rule(s)
The “% pass” column gives the percentage of
conformance regarding the rule, feature class or the
whole dataset.

Benefits and Challenges
Key benefits
Broadening scope of existing validation process for ERM
Providing measures for usability evaluation
Make informed qualitative assertions on the dataset quality and between national
contributions
Challenges
Aggregation where measurements at
different scales and units
Aggregation for inhomogeneous data
Reporting details
 DQ for producers vs. Users
 DQ requirements vs. recommendations

ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK
Next Steps for E.L.F.
Deploy Automatic DQ Process and Rules
to Cloud-based Service Environment
Easy access to commonly agreed rule sets for ELF
Consistent assessment across multiple datasets
Assist in provision of homogeneous data content
Define User-Centric Measures
for an end user application
For example, establish key data measures needed to
assure confidence in the data that will be used to
determine risk scores in natural catastrophe risk
assessment applications for insurance.

Conclusions
There is a need to introduce a better management of quality for reference data
Government policies are key driver for the reference geo-information (Open Data,
INSPIRE, European Location Framework)
Cost effectiveness is important -> automation of quality evaluation is a
prerequisite
User demands > creating trust -> need for authorativiness, accreditation (ISO
19158)
Quality Automation based on ELF will decrease production cost and time -> faster
and more frequent release of reference geo-information (e.g. European datasets)
