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!
