Mapathon for Missing Maps

Date: 20 September 2017
Time: 17:30 - 20:00
Location: IHE Delft Institute for Water Education, Westvest 7, 2611 AX Delft

On 20 September, IHE Delft is hosting a Mapathon for the Missing Maps project.

Mapping Party

During the Mapping Party, volunteers will map the structure of the country based on satellite images, on OpenStreetMap, a detailed, open-source map of the world. Volunteers in the mapping district will later add local information, for example on schools, sanitary provisions, hospitals and water point monitoring in the local language. That way the data on the map will become more relevant on the ground.

We invite everybody to become an ‘online volunteer’ for a night. You don’t have to have any experience; it is easy to learn and we have trained experts available to help you on your way. Bring your laptop and mouse and join the initiative.

Importance of mapping vulnerable areas

Good mapping material is essential for strengthening vulnerable places around the world. Places which are suffering from epidemics, conflicts, natural disasters, poverty or environmental problems, for example. Mapping helps governments to make better (policy) decisions and aid organisations to offer better assistance, because they have more knowledge in advance about medical activities and the distribution of needed relief supplies. In cases of disaster, they are able to react better and quicker.


Missing Maps is an international crowdsourcing initiative through which people from all over the world contribute to the augmentation of the world map on OpenStreetMap. In doing so, they focus on the world’s most vulnerable spots. More than 15,000 people are involved and, together, they have contributed more than 24 million updates. So-called mapathons are being held all over the world to bring the map more up to date, little by little.
