Real life interoperability - Increasing the use of Earth Observation data


Published on

4S Symposium - Portorož - June 4th 2012

In the last decades, use of Earth Observation satellites data has grown considerably. In this context, Geospatial web services technology has provided a new means to provide easy and interoperable access to Earth Observation data. Open Geospatial Consortium (OGC) services have been widely adopted in the Geosciences community, and particularly in the remote sensing community. These services bring seamless integration of heterogeneous ressources from small and big satellites and make Earth Observation data available to a wider range of public users than ever before. Focused on natural disasters management, this presentation will show how an innovative and efficient web application can take advantage of the power of interoperability to provide more complete data to the users

Real life interoperability - Increasing the use of Earth Observation data

  1. 1. REAL LIFE INTEROPERABILITY Increasing the use of Earth Observation data Jérôme GASPERI 4S Symposium - Portorož - June 4th, 2012
  2. 2. Small Satellites, Big Systems
  3. 3. 6m 2m 1m SPOT 5 Speaker SST-100
  4. 4. only data matter
  5. 5. The best data are useless if nobody can get them
  6. 6. Interoperability
  7. 7. Works in Portorož
  8. 8. We need to standardize !
  9. 9. files metadata services A readable one ! (e.g. JPG, TIF, HDF, etc.) A structured (e.g. XML) and standardized (e.g. HMA) description OGC Web Services W*S INTEROPERABILITY format | describe | access
  10. 10. Geospatial Web Services Search metadata Share maps Share vectors Share data CSW WMS WFS WCS
  11. 11. All these things done, we could seamlessly combine data from big or small satellites to provide more complete information to the users
  12. 12. A concrete use case International Charter "Space and Major Disasters" metadata catalog
  13. 13. The Charter aims to provide a unified system of space data acquisition and delivery to those affected by natural or technological disasters [...] The agreement comes from the recognition that no single operator or satellite can match the challenges of natural disaster management.
