Web-based Geoprocessing with Open Source Software – a 52°North perspective

  1. 1. Web-based Geoprocessing with Open Source Software – a 52° North perspective Dr. Theodor Foerster, Bastian Schaeffer & Bastian Baranski OSGIS UK, 22 June 2010
  2. 2. What is SWSL? Sensor Web & Web-based Geoprocessing
  3. 3. What is 52° North? • Platform for innovation – Open Source (GNU GPL / dual license) – Non-profit • 52° North Communities – Sensor Web, Security, ILWIS, Geostatistics, Semantics & Geoprocessing
  4. 4. Geoprocessing Community • Geoprocessing in SDIs – From geodata to geoinformation • 52° North Web Processing Service • Current research – Process integration – Grid Computing – Cloud Computing – Client applications
  5. 5. Where it all started…
  6. 6. Community Facts • 4+ years experience • International contributors • Active mailing list • 150+ mailing list subscribers • 15+ SVN branches – Workflow – Legacy integration –… • 52° North WPS [as de-facto standard] − OWS testbeds & EU projects • www.52north.org/wps
  7. 7. Process integration • Sextante (www.sextantegis.com) – 220+ processes out-of-the-box – Raster & vector capabilities – Fully automated integration • Others – ILWIS (prototypically) – ArcGIS (in latest version, rc4) • 200+ native processes • Python scripts
  8. 8. Grid Computing • scales processing load on distributed nodes (split & merge) Unicore & Globus Toolkit (in progress)
  9. 9. Cloud Computing … is popular
  10. 10. Characteristics • Scalability - the cloud scales the deployed applications automatically on-demand. • On Demand - Resources are consumed in an on- demand fashion; metered services • Efficiency - Cloud Computing enables IT companies to increase utilization rates of their existing hardware significantly. • Outtasking - Cloud users do not need to operate their own large-scale computational infrastructure anymore. Fixed costs can be transformed into variable costs.
  11. 11. Performance tests
  12. 12. Hybrid Cloud (Motivation) 120.000 € 80.000 € Requests 40.000 € 20.000 € Time
  13. 13. Hybrid Cloud (Use Case) WPS Public Cloud WPS WPS WPS Public Cloud Load Balancer WMS WMS Private Cloud Hybrid Cloud WMS WMS WFS WFS WPS
  14. 14. Client applications • JUMP • uDig • gvSig • OpenLayers
  15. 15. WPS OpenLayers Browser-based configuration & execution
  16. 16. Conclusion • Geoprocessing in SDIs enables geoinformation on the web • Process integration – Sustainability & robustness • Grid/Cloud Computing – On-demand & availability • Client applications – Accessing these concepts
