Exploring the Transition from Closed to Open Source in Geospatial Technologies

In this discussion, Gary Lang, VP of Engineering at Autodesk, delves into the evolution of geospatial technologies from a closed-source model, epitomized by the "Cathedral," to an open-source paradigm represented by the "Bazaar." He examines the impact of standards and APIs that facilitate this migration, highlighting the role of successful open-source initiatives and the influence of industry leaders like Google Maps. Lang also addresses the commoditization opportunities presented by open-source software in the geospatial sector and considers the future landscape of technology in this domain.

Presentation Transcript

  1. Gary Lang VP Engineering ISD, Autodesk Opening the possibilities: APIs & Standards -> Open Source

  2. Open Source Geospatial Foundation Two Models: Cathedral and Bazaar

  3. Open Source Geospatial Foundation Autodesk is a Cathedral?

  4. Open Source Geospatial Foundation “Cathedral” • Webster says: • “The principal church in a diocese, so called because in it the bishop has his official chair (Cathedra) or throne. “

  5. Open Source Geospatial Foundation Our Bishop?

  6. Open Source Geospatial Foundation Successful closed source – The Cathedral

  7. Open Source Geospatial Foundation Successful open source – The Bazaar

  8. Open Source Geospatial Foundation The Geospatial Bazaar

  9. Open Source Geospatial Foundation What causes migration of a Company & its Code base from Closed to Open Source?

  10. Open Source Geospatial Foundation Core Context

  11. Open Source Geospatial Foundation Standards Facilitate, drive migration • POSIX, Unix culture -> Linux • HTTP -> Apache • SQL, ODBC, OGIS -> PostGIS • GML, WMS, WFS -> MapServer

  12. Open Source Geospatial Foundation Geospatial Open Source Interest – B.G.

  13. Open Source Geospatial Foundation Then came Google Maps

  14. Open Source Geospatial Foundation AND Google Earth Brings “Mirror Worlds” to the Masses

  15. Open Source Geospatial Foundation Mirror Worlds • “Imagine looking at your computer screen and seeing reality – an image of your city, for instance, complete with moving traffic patterns, or a picture that sketches the state of an entire corporation at this second…. These will soon be available to anyone. David Gelernter 1991 “Mirror Worlds” http://tinyurl.com/rpn2h

  16. Open Source Geospatial Foundation Open APIs But… When will the ads appear?

  17. Open Source Geospatial Foundation Love Google Labs Hate MSFT Yahoo Joins In Mashups!

  18. Open Source Geospatial Foundation Geospatial Open Source Interest – A.G.

  19. Open Source Geospatial Foundation Open Source Geospatial Software and Standards • Standard APIs have facilitated growth. • Open web services including OGC WMS, WFS, • MapServer, Mapbender • OGC Simple feature spec for SQL (SFS) • PostGIS/PostgreSQL • MySQL/MySAM spatial

  20. Open Source Geospatial Foundation Geospatial Open Source Takes Off

  21. Open Source Geospatial Foundation Autodesk goes Open Source • Why we did it • Our users wanted it (we’re too slow) • It makes business sense for MapGuide • It makes business sense for Map • It makes business sense for Topobase.

  22. Open Source Geospatial Foundation Standard APIs created commodization opportunities for web mapping • Drives closed source genres into open source genres • Context (commoditization) is fertile ground for open source • Standard APIs are closely associated with context, and move software genres into context from core. • As standard geospatial APIs emerge (ISO, OGC, Google Maps 2.0,..) open source geospatial will become more ubiquitous.
