Statistical Viewer
Coping with the Complexity
Overview
• What’s DataCove and Ghosting
• EuroStat as a Data Resource
• DataCove Statistical Viewer
• The Was from Here to There
• Conclusions
DataCove e.U.
• Data Modelling: OGC & ISO / INSPIRE based data
modelling
• Data Harmonization: Transforming existing data
to align with standardized data models
• Data Provision: Making data available via OGC &
ISO / INSPIRE compliant web services (WMS,
WFS, SOS)
• Ghosting: Provision of existing data aligned with
INSPIRE
• Observations: Special focus on observational
data on spatial objects (O&M Data Model, Sensor
Web)
DataCove INSPIRE Ghosts
Various datasets online with INSPIRE Formats
• CDDA Protected Sites
• Land Use Data
• Utility & Government Services (Schools)
• Eurostat data for Statistical Units and
Population Distribution (more than
demography!)
• Eurostat dictionary as GML Dictionary
eurostat
• Statistical Office of the European Union
• Wide range of statistical data, i.e.
Demography, Employment, Education,
Migration, Economy
• Spatial Data available, but NUTS regions or
topology

Tables by Theme

Data Explorer 2
• What could we do if this data was available via
INSPIRE...
At DanubeHack2 we started seeing what we
could do with INSPIRE compliant services for:
• suv:VectorStatisticalUnit
• pd:StatisticalDistribution
How did we get there?
• Eurostat Data Ghosted using INSPIRE Data
Specifications and GeoServer:
• suv:VectorStatisticalUnit
• pd:StatisticalDistribution
• Viewer using OpenLayers
• But – there were still quite a few bits missing!
Missing bits
• Queries - no standardized stores queries in
INSPIRE:
• List of all measures
• List of classifications with items per measure
• Features available for a specific measure
• Filters – some pd:StatisticalDistribution
features large
• Filter by selected classification items
PHP Filter
• Depending on Statistical Measure selected,
features can be very large (the Data, not the
Geometry!)
• Statistical Data Provided for different
classifications:
• Male/Female/Total
• Age Groups
• Level of Education
• …
• Only one value can be visualized, so filter before
download!
PHP Filter
• Provide FeatureId & Classification Items (and
Service URI if not default). Example:
• classItem=http://code.datacove.eu/codeList/age/
Y_GE25,http://code.datacove.eu/codeList/sex/M
• featureId=AT_lfst_r_lfu3rt_age_sex_2015
• Returns Feature as JSON, only values
corresponding to classItem
• http://bolegweb.geof.unizg.hr:2017/danubeh
ack2/pd-viewer/api/PD_Filter2.php
Problems Encountered (GeoServer)
• No Stored Queries on Complex Features
→ Made simple features from same tables
• No Stored Queries on Views (simple feature)
→ Created tables instead of views
• Problem with WMS on MultiSurface
→WMS from Simple Features
• Crash when querying multiple complex
features
→Query features individually
Architecture
PostGIS
GeoServer
OGC Services
INSPIRE (WFS):
• Statistical Units (SU)
• Population Distribution (PD)
Additions:
Simple Feature SU (for WMS)
Simple Feature: All Measures for PD
Simple Feature + Stored Query: Classifications for
Measure PD
Simple Feature + Stored Query: FeatureId for Measure,
Country & Year
Web Viewer - Visualize PD Data
by SU:
1. One Measure
2. Aggregate Measures, i.e.
measure1/measure2
Simplifier: return
values for one
classification set
Insights for INSPIRE
• Fitness for Use checks would be valuable:
while PD data logically structured, not ideal
for application development
 include real use cases & usability checks
• Standardized Stored Queries for Data Themes
 some usage dependent, but many reusable
• PD Structure logical in statistical context,
difficult in spatial context
 usability checks
Conclusions
• More and more data online and available, but not
much harmonized ( essential for reuse!)
• INSPIRE Data Specifications good start, but:
• Difficult to implement with current technology
• Standardized Stored Queries missing
• Fitness for Use should be further analysed
• Important for enabling applications across data
sources

  • 2. Overview • What’s DataCove and Ghosting • EuroStat as a Data Resource • DataCove Statistical Viewer • The Was from Here to There • Conclusions
  • 3. DataCove e.U. • Data Modelling: OGC & ISO / INSPIRE based data modelling • Data Harmonization: Transforming existing data to align with standardized data models • Data Provision: Making data available via OGC & ISO / INSPIRE compliant web services (WMS, WFS, SOS) • Ghosting: Provision of existing data aligned with INSPIRE • Observations: Special focus on observational data on spatial objects (O&M Data Model, Sensor Web)
  • 4. DataCove INSPIRE Ghosts Various datasets online with INSPIRE Formats • CDDA Protected Sites • Land Use Data • Utility & Government Services (Schools) • Eurostat data for Statistical Units and Population Distribution (more than demography!) • Eurostat dictionary as GML Dictionary
  • 5. eurostat • Statistical Office of the European Union • Wide range of statistical data, i.e. Demography, Employment, Education, Migration, Economy • Spatial Data available, but NUTS regions or topology http://ec.europa.eu/eurostat/data/database
  • 9. • What could we do if this data was available via INSPIRE... At DanubeHack2 we started seeing what we could do with INSPIRE compliant services for: • suv:VectorStatisticalUnit • pd:StatisticalDistribution
  • 10.
  • 11.
  • 12.
  • 13.
  • 14.
  • 15. How did we get there? • Eurostat Data Ghosted using INSPIRE Data Specifications and GeoServer: • suv:VectorStatisticalUnit • pd:StatisticalDistribution • Viewer using OpenLayers • But – there were still quite a few bits missing!
  • 16. Missing bits • Queries - no standardized stores queries in INSPIRE: • List of all measures • List of classifications with items per measure • Features available for a specific measure • Filters – some pd:StatisticalDistribution features large • Filter by selected classification items
  • 17. PHP Filter • Depending on Statistical Measure selected, features can be very large (the Data, not the Geometry!) • Statistical Data Provided for different classifications: • Male/Female/Total • Age Groups • Level of Education • … • Only one value can be visualized, so filter before download!
  • 18. PHP Filter • Provide FeatureId & Classification Items (and Service URI if not default). Example: • classItem=http://code.datacove.eu/codeList/age/ Y_GE25,http://code.datacove.eu/codeList/sex/M • featureId=AT_lfst_r_lfu3rt_age_sex_2015 • Returns Feature as JSON, only values corresponding to classItem • http://bolegweb.geof.unizg.hr:2017/danubeh ack2/pd-viewer/api/PD_Filter2.php
  • 19. Problems Encountered (GeoServer) • No Stored Queries on Complex Features → Made simple features from same tables • No Stored Queries on Views (simple feature) → Created tables instead of views • Problem with WMS on MultiSurface →WMS from Simple Features • Crash when querying multiple complex features →Query features individually
  • 20. Architecture PostGIS GeoServer OGC Services INSPIRE (WFS): • Statistical Units (SU) • Population Distribution (PD) Additions: Simple Feature SU (for WMS) Simple Feature: All Measures for PD Simple Feature + Stored Query: Classifications for Measure PD Simple Feature + Stored Query: FeatureId for Measure, Country & Year Web Viewer - Visualize PD Data by SU: 1. One Measure 2. Aggregate Measures, i.e. measure1/measure2 Simplifier: return values for one classification set
  • 21. Insights for INSPIRE • Fitness for Use checks would be valuable: while PD data logically structured, not ideal for application development  include real use cases & usability checks • Standardized Stored Queries for Data Themes  some usage dependent, but many reusable • PD Structure logical in statistical context, difficult in spatial context  usability checks
  • 22. Conclusions • More and more data online and available, but not much harmonized ( essential for reuse!) • INSPIRE Data Specifications good start, but: • Difficult to implement with current technology • Standardized Stored Queries missing • Fitness for Use should be further analysed • Important for enabling applications across data sources Statistical Viewer: http://bolegweb.geof.unizg.hr:2017/danubehack2/pd-viewer/
