The INSPIRE Hackathon is a series of collaborative events for developers, researchers, and others interested in open data and volunteered geographic information. It is organized by Plan4all, a non-profit association with members from over 20 countries. The hackathon focuses on making sustained use of Copernicus, INSPIRE, and GEOSS data. A special edition was held in Nairobi in 2019, the first time in Africa, to explore topics like agriculture, climate, tourism, and citizen science using open datasets. Participants presented results like applications for food security, climatic services, land use mapping, and Internet of Things technologies for Africa.
