2 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?

3 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 geoportal referred to in paragraph 1. Member States may also provide access to those services through their own access points.

4 For EO folks: INSPIRE as a «onestop-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)

6 Catching End Users needs and requirements Growing demand of geoinformation to support environmental monitoring and planning and for Civil Protection. Necessary to use EO data from different sensors with different characteristics (optical, SAR, spatial resolution, etc.). Availability of huge amount of EO data (Big Data) within archives with automatic catalogue&search functionalities System for elaborating EO and non EO data Data fusion and change detection algorithms Direct access to EO Big Data INSPIRE provides easy access to non-eo data all over Europe Exploitation of INSPIRE

7 Operational workflow EO Big Data (L0,L1) ESA ASI... Single sensor processing systems Basic and aggregated products (L2, L3) Advanced processing Multi sensor Data fusion Non EO data Local/National Pan European Big Repositories INSPIRE System for elaborating EO and non EO data Data fusion and change detection algorithms Direct access to EO Big Data Exploitation of INSPIRE Added value products (L3+) Direct answer to end user requirements

8 Example Use Case Flooding event occurred in Sardinia o EO Input: SAR scene acquired after the event SAR scenes from a same sensor Present before case and after the event, for more sensors (e.g. TSX, o EO Input: CSK, Sentinel-1) - one Optical TSX scenes before acquired and after after the the event provided (e.g. Sentinel-2, for free* Landsat8, RapidEye) o Ancillary - COSMO data scenes from acquired INSPIRE during (themes): and after the event** o Non-EO Elevation Input: DEM, road network Product: Administrative map flooded units areas (at the timing of acquisition), provided to the Sardinia Transport Region networks authorities Buildings * Astrium courtesy Production and industrial facilities ** Data being provided Big Data & INSPIREd approach 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

9 Example Use Case - INSPIREd Theme: Elevation Use: Remove reliefs shadows An accurate DEM allows to define slope and aspect of the territory vs. SAR sensor view SAR sensors looking direction Mountain side facing the SAR sensors Mountain side shadowed to the SAR sensor Theme: Land Cover Use: Reduce errors 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

10 Example Use Case - INSPIREd Theme: Land use Use: remove false detection Airport landing area appears very similar to water on a SAR image (left), leading often to errors. Reliable land use map allows to remove or highlight such areas

11 Example Use Case - INSPIREd Theme: Cadastral Parcels Theme: Buildings Theme: Production and industrial facilities Use: classification of damage level/type Flooded area along a river - Mainly cultivated fields - Small houses - Rural facilities - Nearby city area

12 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
