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

Web-based Geoprocessing with Open Source Software – a 52° North perspective Dr. Theodor Foerster, Bastian Schaeffer & Bastian Baranski OSGIS UK, 22 June 2010

What is SWSL? Sensor Web & Web-based Geoprocessing

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

Geoprocessing Community • Geoprocessing in SDIs – From geodata to geoinformation • 52° North Web Processing Service • Current research – Process integration – Grid Computing – Cloud Computing – Client applications

Where it all started…

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

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

Grid Computing • scales processing load on distributed nodes (split & merge) Unicore & Globus Toolkit (in progress)

Cloud Computing … is popular

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.

Performance tests

Hybrid Cloud (Motivation) 120.000 € 80.000 € Requests 40.000 € 20.000 € Time

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

Client applications • JUMP • uDig • gvSig • OpenLayers

WPS OpenLayers Browser-based configuration & execution

Conclusion • Geoprocessing in SDIs enables geoinformation on the web • Process integration – Sustainability & robustness • Grid/Cloud Computing – On-demand & availability • Client applications – Accessing these concepts
