there is a substantial FOSS GIS adoption occurring in some South American governments,
this uptake maybe occurring for a different mix of reasons than observed or expected with FOSS adoptions in the Global North.
South America has seen a unique variety of laws and decrees at the city, state, and federal levels promoting FOSS use on government computers
Figure 1. Notable country-level policies in South America related to goverment use of FOSS
Beyond encouraging FOSS, some governments even mandate its use for state business. For examples,
Venezuela’s ‘Infogobierno’ law requires public institutions migrate to FOSS
Bolivia has enacted a series of decrees leading toward public sector migration to FOSS
the tendency to adopt strict mandates of FOSS was more common in Latin America and Africa than in other parts of the world. Policies in other regions tended to take more of a hands-off advisory role.
Technical factors
Economic factors
Social factors
Political factors
Recent government crackdowns on illegal software copying are leading public institutions to look for lower-cost software alternatives
Some have recognized FOSS solutions as a way to not only economize, but also foster local skills, develop context-specific applications, and institute social changes
These licenses also allow modification and redistribution of the code, providing a way to fix, enhance, or internationalize the software without waiting for a vendor to release a (potentially costly) upgrade.
An attractive element of FOSS for the public sector is that the software can be distributed without licensing fees
The amount of money required to keep proprietary software running in government offices is substantial
The reasons for government promotion of FOSS in South America go beyond economics, and involve attitudes about society, sovereignty, and the role of the state.
Chan (2004) noted that this line of reasoning represented a key difference from FOSS promotion in North America, where supporters tended to emphasize FOSS’s protection of consumer freedoms.
the idea of FOSS is an avenue to independence from the perceived imperialism of US-based proprietary software companies has appeared across social stratum.
Free software represents the values: equality, freedom, sovereignty, right to choose, democracy, and development.
four countries, which have supported FOSS through legislation or decree at the national level, using FOSS GIS for their principal map viewers (Bolivia, Ecuador, Uruguay, and Venezuela).
Brazil is the only country with national support for FOSS that is not using FOSS in its principal map viewer
Most of the provincial sites in the below table are using well-known and basic FOSS GIS software.
stability and long-term maintenance of some of the sites appear to be challenges.
exchange troubleshooting tips,
share ideas and success stories,
post employment information,
arrange conferences and meetups of people with similar skills and interests.
An important indication of FOSS GIS presence in any region is the local production and improvement of software
FOSS development is evidence of this process occurring. FOSS GIS development efforts in South America include the aforementioned
Ibero-America has incubated several FOSS GIS programs that are widely used in South America.
One of these is gvSIG, a desktop GIS program developed in Valencia, Spain.
Another GIS, called SPRING, was developed by the Brazilian National Institute for Space Research (INPE).
Other open source GIS tools developed by Brazilian government and educational institutions include i3Geo, E-foto, and TerraLib
FOSS GIS Brasil magazine
Geoinquietos Argentina
FOSS.4GIS.GOV conferences in Brazil
the most ambitious effort ever to publish information about FOSS GIS in periodical format was a Portuguese language magazine.
The magazine included articles about:
the main objective is to share knowledge and effort
the group is completely anarchic; there is no hierarchy of participants.
jovial, relaxed, and occasionally very technical banter
The Geoinquietos Argentina chapter has been one of the most active of these groups,
repeatedly organizing conferences that attract hundreds of people from the Southern Cone area of South America and beyond.
The success of Geoinquietos Argentina at gathering the FOSS GIS community was noticed in other areas of South America.
Actually, several notable gatherings of open source GIS software enthusiasts have occurred in Brazil’s capital, but they have largely focused on government applications.
the FOSS.4GIS.GOV conference brought together hundreds of professionals.
This article discussed three case studies of particularly successful efforts to promote FOSS GIS and rally local user groups through education and sharing of technical expertise.
The common thread between these case studies is their ability to connect individuals.
