1) Open source GIS involves open source GIS software, open data, open licenses, and standards. It is an alternative to proprietary GIS software. 2) Approaches to implementing open source GIS include using only open source, only proprietary software, or a hybrid. Considerations include resources, government policy, and substitutability of open source for proprietary software. 3) Case studies from South Korea demonstrate various uses of open source GIS, including geospatial image services, satellite image management, traffic and weather mapping, and building information modeling.

4. What is Open Source GIS?
What is GIS?
-Geographical Information System
-Geomatic, Geo-Scientific, Geo-Service
-Geospatial Information System
Geo is Location-based
Information is Database
System consists of Hardware, Software, Data, and Liveware(Human Resources)
Generally, Open Source GIS is related to software
Software
Data
Hardware
Liveware
Survey

5. What is Open Source GIS?
Open Source GIS contains
- Open Source GIS Software Program (PostGIS, GeoServer, QGIS, Openlayers)
- Open Data (Open Street Map)
- Open License Policy(GPL, LGPL)
- OGC Standards
- OSGEO community

6. What is Open Source GIS?
 FOSS(Free Open Source Software) is open but doesn’t mean it’s No-Cost
 Recently, FOSS is considered as Commercial SW
 FOSS is contrasted to Closed or Proprietary SW

7. What is Open Source GIS?
Trends of Open Source GIS
 Google Earth adopts open source GIS Library - GDAL
 Conversion of ArcGIS GeoPortal Server into Open Source in 2011
 All Products of ArcGIS Series adopt GDAL
 Transformation of AutoCAD MapGuide, MetaCRS, FDO into Open
Source and Contribution to OSGEO
 85 out of 135 3rd Party Libraries are Open Source
Appearance of Commercial Open Source GIS Companies
