Organizing a MapSwipe event, aka a MapSwipe-a-thon is a simple, yet powerful way to make an impact. MapSwipe (see also is an open-source mobile app developed in collaboration with the Missing Maps Project as an easy way for people to contribute to humanitarian mapping efforts. MapSwipe-a-thons work like other mapathons: a number of people work together on mapping a region, either physically in the same room, or remotely by joining a chat room or video call.

Before your event

  • Review the introduction & training presentation and other resources that you can find below.
  • Download the MapSwipe app from the Apple or Google store
  • Familiarize yourself with the app and missions - it is very important to do the tutorials!
  • Plan & promote your event.
  • Get together, pick a mission, get swiping!

Thinking of hosting a large event?

If you intend to organise a MapSwipe event, start by estimating how many people will join and how long each of them will map. Rough estimates are fine, for instance "I think 50 people will join the event and map for 2h" is a good starting point. This gives you an event size in app-hours. In this example, 50 * 2 = 100 app-hours. This is important because additional support may be required.

Based on this event size, you might need to take different approaches:

  • Under 100 app-hours: no need for any special preparation. Read through the resources linked below and feel free to use it to introduce MapSwipe during the event to your attendees.
  • Between 100 and 500 app-hours: there might be a need for some planning and support during the event to ensure there is enough work to do, particularly if your event is concentrated over just a few hours (many people working for only a few hours at the same time). Email with details so that the team can support you and plan capacity internally.
  • Over 1000 app-hours: this is a big event which will require more planning, setup and support before and during the event. Email for more information.

When emailing, please include the following details:

  • who you are, and what organisation you represent, if any.
  • when you plan on running your event (date/time).
  • how many people you expect to join.
  • how long the event will run for.
  • where the event will take place (online is a valid option!).

Large events, have large impact on the MapSwipe infrastructure and the volunteer team behind it. A financial contribution via the MapSwipe Open Collective is appreciated.
