Open source GIS software has been applied in numerous projects across the globe and has been proved to be very efficient and effective. These case studies show how different organizations have used open source GIS to solve their problems and meet their objectives. In this article, several successful projects that have applied open source GIS solutions will be discussed.
Collaborative Mapping for Disaster Response
Open source mapping tool known as OpenStreetMap (OSM) was used to create detailed maps of the areas impacted by the 2010 Haiti earthquake. This mapping was done by volunteers from different parts of the world and the information was very vital to the relief agencies and first aiders. This is where open source GIS comes into play, it showed how the power of the crowd and community can be harnessed in disaster response.
Improving Public Health with Open Source GIS
WHO has effectively used Open Source GIS applications in managing diseases outbreak and its control. In the 2014-2016 Ebola outbreak in West Africa, WHO applied QGIS and GeoServer as open source tools for data gathering, analysis, mapping, and dissemination to the stakeholders. The real-time data sharing and visualization capabilities that were provided by open source GIS were very useful in the coordination of the response.
Sustainable Urban Planning with Open Source GIS
Trento city in Italy has been one of the early adopters of open source GIS in the planning and management of the city. Since 2005 the municipality has been supporting the enhancement and the further development of the GRASS GIS, an open source software for spatial analysis and modeling. This paper shows that through the use of open source GIS, Trento has been able to produce maps, study the growth of the city and design good planning strategies.
Empowering Local Communities with Open Source GIS
Kibera slum in Nairobi Kenya is one of the areas that show how open source GIS can help the local communities. The Kibera Community Development Agenda (K’OBED) employed open source tools like the OSM and QGIS in mapping out the slum and its needs. This mapping exercise was not only useful in generating information that was useful to local organizations but also in creating ownership and participation.
Precision Agriculture with Open Source GIS
The application of open source GIS has greatly helped in the improvement of precision agriculture. PAD has been using open source technologies such as QGIS and Kobo Toolbox to gather data on soil, crops, and weather. Through offering farmers data analysis, PAD has been able to enhance the output and efficiency of small scale farming.
Conclusion
These case studies show how open source GIS can change the world in different fields ranging from disaster response to urban planning and precision agriculture. This paper has shown that through the use of flexibility, affordability and cooperation of open source GIS, organizations have been able to come up with new solutions and meet their objectives. Thus, as open source GIS remains a rapidly growing and popular field, there will be even more successful projects in the future, contributing to the advancement of areas like environmental conservation, public health, and community development.
