On 20 September, IHE Delft is hosting a Mapathon for the Missing Maps project. This event is organized in cooperation with the Red Cross. Everybody is welcome here to map a part of the world where help is needed. Red Cross and other organisations use these maps ("geo-information") during their operations in areas which are not well mapped today. In this mapathon we will map an area in Zambia.

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. 


Everybody is welcome to join the Mapping Party, which will be held at IHE Delft, free of charge. Specialist technical knowledge is not a prerequisite.  

Are you interested in joining: please sign up by filling in this form. We will make sure that you are registered to join the party. 


Missing Maps continues

Missing Maps is an initiative of the Red Cross, MSF and other NGOs aiming to map the most vulnerable places in the developing world. Learn more about the project here.

You can get involved as an individual here, even before & after the Mapping party has ended, or if you are unable to attend. The Missing Maps organizers will let you know by email when there are tasks that need doing – or when there are other mapping parties, like this one, being organized.
