Data party is a collaborative and often informal event where participants come together to curate, manage, visualise and share geospatial datasets openly available. Data parties can gather a diverse community from higher-education students, staff, industrial actors and citizens to work together toward transparent, accessible and sustainable (research) data management. This inclusive approach builds awareness on research data resources, encouraging dialogue across perspectives and building trust and ownership on the results. Data parties are also an efficient way to manage research data - multiple people working together with snacks and refreshments achieve the goals in a couple of hours, when an individual would spend several workdays for the task.
