2 Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 2 Presentation structure Project s objectives A few words about the Institution Step 1: from a tape repository to a digital repository Step 2: extending this digital repository by building services around it Conclusion

3 Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 3 European Commission (EC) The Commission is independent of national governments. Its job is to represent and uphold the interests of the European Union (EU) as a whole. It drafts proposals for new European laws, which it presents to the European Parliament and the Council. It is also the EU s executive arm in other words, it is responsible for implementing the decisions of Parliament and the Council.

Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 5 Use of satellite imagery at the JRC Twenty projects using Satellite Remote Sensing (SRS) data Annual expenditure on SRS data

5 Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 5 Use of satellite imagery at the JRC Twenty projects using Satellite Remote Sensing (SRS) data Annual expenditure on SRS data > 7 M s of Low Resolution images More than High Resolution images Over km 2 of VHR images Overall, more than 55 TB of SRS data Scattered storage and no central catalogue

Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 6 First setup of an online archive Initiated on the archive of one project end 2003.

6 Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 6 First setup of an online archive Initiated on the archive of one project end MARS-PAC project is the largest civil purchaser of satellite imagery in the EU. Largest archive of HR and VHR data in the JRC Goal: To be able to search for images from a web browser, to visualize them and get a link to the files.

Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 7 Characteristics of this first setup SRS data loading application Works with raw HR and VHR data Extracts metadata and stores them in

7 Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 7 Characteristics of this first setup SRS data loading application Works with raw HR and VHR data Extracts metadata and stores them in a spatial DB (PostgreSQL/PostGIS) SRS data pre-processing Conversion of the data to TIFF format and georeferencing. Histogram stretching and conversion to ECW SRS data dissemination Search and browse imagery (ECW) Web mapping (Mapserver) Download of raw or georeferenced data

Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 8 Outcome of this first setup Successful as initial objectives were reached Several limitations were identified: disk space not easily

8 Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 8 Outcome of this first setup Successful as initial objectives were reached Several limitations were identified: disk space not easily extendable restricted to raw HR and VHR no fine grained authentication possible (users and IPRs) no WMS or WCS service severe restrictions in usability by other projects at JRC Management wish to build on it and provide a site-wide service Expected cost savings in hardware and staff

10 Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 10 CID portal project objectives Provide a centralized storage facility with backup and a data upload application. Provide a data acquisition service. Provide a service with IT infrastructure in High Availability mode. Build a central catalogue of all SRS data available at JRC with a CSW service and a web interface to the catalogue. Provide secure access according to IPRs and user credentials via direct file access at high speed (NFS v4, CIFS) OGC protocols (WMS, WCS) other (web mapping, KML...) Provide some SRS data processing services: [semi-]automated orthorectification

11 Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 11 CID portal Staff and Budget Budget to initiate the project: Hardware: 200 K Software development: 130 K Orthorectification software Modules for authentication and catalogue interface Annual resources: IT consultancy and small developments: 50 K 1.5 engineers and 0.7 IT technician.

Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 14 Open source software and CID The preferred option at CID because: Knowledge available within CID staff

14 Victoria, BC, Canada on 25 September 2007 FOSS4G2007 Conference 14 Open source software and CID The preferred option at CID because: Knowledge available within CID staff Almost all functionalities required are available in FOSS Some functionalities available only in FOSS! Good support from the user community No cost to acquire the piece of software
