I-1. What is Open Source SW?

q  Open source SW(OSS) is the computer SW that is available in source code form under certain licenses.

q  Users of OSS are permitted to use, copy, study, change, improve and even redistribute those OSS freely.

q  ‘Free’ does not mean ‘Free of Charge’ but ‘Freedom’

Cathedral Bazaar

Leverage own knowledge Leverage others knowledge too

<Closed Development> <Open Development>

§ 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

è  Leveraging inside & outside knowledge

q  Open Source Software Development Model

I-2. Cathedral vs. Bazaar


q  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

q  Benefits of Open Source Software purported by OSS Community

§  Save money, save resources, increase stability, access to source code, access to skilled community of dev

elopers

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

q  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 imp

ortant benefit over proprietary.

q  Open Source GIS

•  FOSS4G : Free Open Source Software for Geo-Spatial

•  GeoFOSS : GeoSpatial Free Open Source Software


q  Current State & Needs of Open Source GIS

ü  Boom-up of Open Source & Open Source GIS - Around 300 ~ 400 Open Source GIS projects are available (Freegis.org, 2011) ü  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 - AutoDesk opend 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 ü  Active adoption of Open Source GIS in UN, EU, USA , Canada and other countries

Current State

ü  Want to meet lots of needs of GIS from public sectors ü  Want More with Less!!

ü  Want to replicate other people & institution’s experience

ü  Want to manage & modify the system by ourselves!!

Necessity

II. Open Source GIS

II-2. Why Open Source GIS?


q  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

V-1. Wrap-up V. Wrap-up

• Open Source GIS is basically free.

• The price of commercial Open Source GIS is lower than proprietary one Cost Reduction

• Almost all the Open Source GIS is compliant with OGC standards

• Open Source GIS can be used with existing proprietary GIS Interoperability

• Anybody can modify & upgrade the system from the source code level

• Can easily replicate or migrate success cases to their system Opened

Source Code

• Collaboration, sharing & community based SW development model

• Source code will be managed by community not by company

• Neutrality from specific technology or company

• Anybody can join and contribute to Open Source GIS with OSGeo

Collaboration based SW

• Open Source GIS is now comparable with commercial proprietary GIS

• Open Source GIS is now actively adopted & used all around the world Advance of Ope

n Source GIS
