Workshop Big Data Roma, 26/11/2013
INSPIRE is many things:
• Yet another Directive of the European Union?• An instrument of standardization of geospatial metadata• The attempt to define “reference themes and layers” at
pan-European level • The standardization of 34 geospatial “Data Themes”• An obligation of the member states to make accessible
their geospatial data through INSPIRE services• An example of “Big Data” in the wild• Many other …
But from a final user perspective, what should it be?
INSPIRE as a «one-stop-shop» for geospatial data
• Whilst INSPIRE is based on the infrastructures of the Member States, the INSPIRE Directive also requires that:
• “The Commission shall establish and operate an INSPIRE geo-portal at Community level”.
• In addition Article 15(2) of the Directive requires:
• “Member States shall provide access to the services referred to in Article 11(1) through the INSPIRE geo-portal referred to in paragraph 1. Member States may also provide access to those services through their own access points.”
For EO folks: INSPIRE as a «one-stop-
shop» for ancillary data
• Cross-border (from all member states)
• Cross-language (thesaurus enabled searches)
• Cross-domain (34 data themes)
• Cross-scale (from global to very local)
• Cross-time (huge amount of historical data)

System for elaborating EO and non EO data
Example Use Case
Present caseo EO Input:
- one TSX scene acquired after the event provided for free*- COSMO scenes acquired during and after the event**
o Non-EO Input: DEM, road network
Product: map flooded areas (at the timing of acquisition), provided to the Sardinia Region authorities
Flooding event occurred in Sardinia
* Astrium courtesy
** Data being provided
Big Data & INSPIREd approacho EO Input:
– SAR scene acquired after the event– SAR scenes from a same sensor before and after the event, for more sensors (e.g. TSX,
CSK, Sentinel-1)– Optical scenes before and after the event (e.g. Sentinel-2, Landsat8, RapidEye)
o Ancillary data from INSPIRE (themes): – Elevation– Administrative units– Transport networks– Buildings– Production and industrial facilities
Products provided to the Sardinia Region authorities:– map of flooded areas (at the timing of acquisition) – map of damaged areas– classification of damage level/type
Example Use Case - INSPIREd
Theme: ElevationUse: Remove reliefs’ shadows
SAR sensors’ looking direction
Mountain side facing the SAR sensors
Mountain side shadowed to the SAR sensor
An accurate DEM allows to define slope and aspect of the territory vs. SAR sensor view
Water detected (left image) -> from a Land Cover map the area is composed of trees and rock (as confirmed in left image using Bing). So water pounds are very unlikely there
Theme: Land CoverUse: Reduce errors
Theme: Land useUse: remove false detection
Airport landing area appears very similar to water on a SAR image (left), leading often to errors (middle).Reliable land use map (right) allows to remove or highlight such areas
Example Use Case - INSPIREd
Theme: Cadastral ParcelsTheme: BuildingsTheme: Production and industrial facilitiesUse: classification of damage level/type
Flooded area along a river- Mainly cultivated fields- Small houses- Rural facilities- Nearby city area
Example Use Case - INSPIREd
Challenges of «INSPIREd computing for EO based services»
• Integration into an EO production workflow – exploit backoffice interfaces (CSW) of the geoportal?
• Integration with ESA catalogues (EOLI/ngEO) – in order to become a real “one-stop shop” for EO workers
• Integration of heterogeneous authentication systems – go Open Data ?
• Establishment of a feedback loop to INSPIRE of relevant products
Thank you!
