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

8. What is Open Source GIS?
OSGeo Community
OSGeo
- Open Source Geospatial Foundation
• Established in Feb 4th 2006 in
Chicago, USA
• Goal: to support Open Source GIS
SW and promote to be used in many
fields
• Non-Commercial Non-Government
Organization
• Community for FOSS4G Community

10. Approach to Open Source GIS
Methodology of Building GIS
1.Usage of Closed S/W
2.Usage of Open Source S/W
3.Hybrid Usage of Closed and Open Source
ClosedOpen
