A mapathon (sometime written map-a-thon) is a coordinated mapping event and a kind of editathon. The public is invited to make online map improvements in their local area to improve coverage and to help disaster risk assessment and energy management.
Mapathons use an online site for storing map data, such as OpenStreetMap. Google Maps was also an option until 2017. A mapathon is organized by a respective organization or a non-profit organisation or local government.
