3 AGF 2012 – Open Source Session Presentation 19/09 Shin, I-1. What is Open Source SW?  Open source SW(OSS) is the computer SW that is available in source code form under certain licenses.  Users of OSS are permitted to use, copy, study, change, improve and even redistribute those OSS freely.  ‘Free’ does not mean ‘Free of Charge’ but ‘Freedom’ I. Overview of Open Source SW 3 FreedomOfSoftware FreedomofRedistribute FreedomofModifyFreedomofCopy FreedomofUse

4 AGF 2012 – Open Source Session Presentation 19/09 Shin, Cathedral Bazaar Leverage own knowledge Leverage others knowledge too  Designed and developed by inside R&D lab  Inside knowledge, intellectual property, experiences  Idling knowledge, limited leveraging outside knowledge  Designed and developed with other outside partners  Inside knowledge + outside knowledge  ‘We are smarter than Me!!’ In-House Development Collaborative Development  Leveraging inside & outside knowledge I. Overview of Open Source SW 4  Open Source Software Development Model I-2. Cathedral vs. Bazaar

5 AGF 2012 – Open Source Session Presentation 19/09 Shin,  Open Source SW vs. Freeware 5 Users have the right to access &modify the source codes. In case original programmer disappeared, users & developer group of the S/W usually keep its support to the S/W. OSS usually has the strong users & developers group that manage and maintain the project OSS Freeware  OSS is different from Freeware  Antonym of OSS would be ‘Closed Source S/W’ or ‘Proprietary S/W’  Recently OSS is also regarded as ‘Commercial S/W’ Freeware is usually distributed in a form of binary at ‘Free of Charge’, but does not open source codes itself. Developer of freeware could abandon development at any time and then final version will be the last version of the freeware. No enhancements will be made by others. Possibility of changing its licensing policy I-3. Open Source SW vs. Freeware I. Overview of Open Source SW

6 AGF 2012 – Open Source Session Presentation 19/09 Shin, I-4. Benefits of Open Source SW 6  Benefits of Open Source Software purported by OSS Community  Save money, save resources, increase stability, access to source code, access to skilled community of developers Develop the society by sharing technology & outcomes!! 1. Technological Aspects 2. Economical Aspects 3. Business Aspects 4. Other Aspects Rapid development of high- class SW Increased stability by skilled community review Reduce technological gap to leading proprietary SW company Internalize outside SW developer resources Very low adoption cost Reduce SW development cost Easy to customize Reuse successful story Extend company’s products portfolio Open up new market by providing diversified services & products Improve brand image of company Reduce energy Self-Satisfaction Help society I. Overview of Open Source SW

7 AGF 2012 – Open Source Session Presentation 19/09 Shin, 7  Open Source Advantages over Commercial SW  Open source’s price tag is clearly important driver. OSS is practically cheaper than commercial one.  57% said that accessibility to source code really matters and 41% cited community code review as an important benefit over proprietary.  Price &open source code are key factors! * Source : Barracuda Networks I-4. Benefits of Open Source SW I. Overview of Open Source SW

8 AGF 2012 – Open Source Session Presentation 19/09 Shin, 8 II-1. What is Open Source GIS? II. Open Source GIS  Open Source GIS FOSS4G : Free Open Source Software for Geo-Spatial GeoFOSS : GeoSpatial Free Open Source Software

9 AGF 2012 – Open Source Session Presentation 19/09 Shin, 9  Current State & Needs of Open Source GIS Boom-up of Open Source &Open Source GIS - Around 300~400 Open Source GIS projects are available (Freegis.org, 2011) Advance of Open Source GIS - OSGeo Foundation : Commercial proprietary GIS SW can be replaced with Open Source GIS - Google used Open Source based GDAL in its Google Earth program - AutoDeskopend the source code of MapGuide, FDO &MetaCRS and then donated those to OSGeo - ESRI actively used GDAL and also changed its ArcGIS GeoPortal Server to Open Source based one Active adoption of Open Source GIS in UN, EU, USA, Canada and other countries Current State Want to meet lots of needs of GIS from public sectors Want More with Less!! Want to replicate other people & institution’s experience Want to manage & modify the system by ourselves!! Necessity II. Open Source GIS II-2. Why Open Source GIS?

10 AGF 2012 – Open Source Session Presentation 19/09 Shin, 10  Characteristics of GIS  GIS = Vertical Set of Many Software Interoperability is very crucial among components Linux, Apache, PHP are Horizontal based Software GIS is Vertical Architecture based one from DB to web client  GIS as Public Infrastructure = Spatial Data Infrastructure Vendor neutral, standard based architecture is very important Active standardization by ISO, OGC  Open Source GIS as another Lego Block Active implementation of “Standard Compatibility” by Open Source GIS Open Source GIS could replace commercial proprietary SW/Components II.
