I-1. What is Open Source SW?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’

• 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

OSSOSS FreewareFreeware

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

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!!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

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 Price &open source code are key factors!factors!

• FOSS4G : Free Open Source Software for Geo-Spatial

• GeoFOSS : GeoSpatial Free Open Source Software



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-2. Why Open Source GIS?II-2. Why Open Source GIS?



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
