Abstract• An OSS Success Story: the case of GIS&RS from the

South Pacific region

• Abstract: The use of Open Source Software for Geographic Information Systems and Remote Sensing (GIS&RS) in the Pacific regions is an important case study in the benefits of OSS for developing countries. The success of OSS for GIS&RS can be related to the many unique challenges and conditions that the Pacific offers. This presentation looks at these challenges and conditions using the analytical framework that Schwelk and English (2012) have used to analyse other cases in OSGeo. A history of GIS&RS is provided along with the characteristics of the community that has developed GIS&RS

• Open Geo. use to addresses this question by looking at GIS&RS in the Pacific begins the process by documenting its history..

OSGeo

• “Open source GIS software makes a major public goods contribution by giving average people, especially those in developing countries, access to free GIS software.” OSGeo Case Study: An example of the evolving OSS Ecosystem.

SOPAC• The GIS/RS Special Interest Group of the

Pacific Islands Chapter of Internet Society GIS/RS SIG has been instrumental in the promotion of Open Source spearheaded by the Pacific Applied and Geoscience Commission (SOPAC) by making source code available to its Stakeholders starting with the GIS for Utilities Project in 1997.

SOPAC

• Process and deliver timely GIS outputs, free of dependence on external vendors or licensing constraints.

USP

• Incorporating FOSS in a number of GIS courses, and students are experiencing desktop GIS with a range of FOSS and commercial software.

• “FOSS GIS applications have seen important developments in the last few years. These have been particularly significant in the areas of desktop GIS for general mapping, and in the usability of desktop mapping applications by non-IT specialists. This has increased the opportunities for projects and organisations with limited budgets to develop desktop mapping capacity,” Conway Pene
