Features & Capabilities

Make a meaningful impact from your phone, one swipe at a time.

MapSwipe is part of the Missing Maps project. It is a free, open-source app that lets anyone contribute to humanitarian and development projects in just minutes a day. No mapping experience needed: review satellite imagery, identify features like buildings, roads, and waterways, and help validate map data used by organizations around the world.

The data you generate supports humanitarian organizations, researchers, and local communities, making OpenStreetMap data more accessible for disaster response, public health, climate resilience, and sustainable development.

How you can contribute:

  • Find Features: Swipe through satellite imagery to spot buildings, roadways, waterways, and more
  • Compare Dates: Review before-and-after imagery to detect environmental changes and assess damage
  • Validate Footprints: Check building footprints and flag areas that need remapping
  • Check Completeness: Compare mapped data against aerial imagery to find gaps
  • Assess Images: Review photographs to confirm features and improve machine learning tools
  • Locate Objects: Mark rooftops, solar panels, trees, and other features to help train machine learning models

Your swipes have real impact. MapSwipe is managed by a volunteer-led team with support from the American Red Cross, British Red Cross, Canadian Red Cross, HeiGIT, Humanitarian OpenStreetMap Team, Médecins Sans Frontières, and Togglecorp.

Download MapSwipe and join a global community putting the world's most vulnerable places on the map.

I love being able to use my phone for something that helps other people instead of just social media, BUT using this app is an exercise in frustration due to bugs. By far the most frustrating is that when you’re in the middle of a mapping task, the app will randomly white out the screen and then flash the MapSwipe logo at you while saying “loading groups” and a button that says something like “if this takes too long, tap here to go back to the home screen.” I’ve waited several minutes, and it never finishes “loading the groups.” And the only way to leave that screen is to go back to home or to close the app. Either way, you lose your entire mapping task progress. I tried joining a random group to see if it would stop trying to “load groups,” but it still happened. It’s incredibly discouraging, and I have to restrain myself from rushing through a task because I’m afraid that the groups thing is going to appear and make all the time I spent be wasted. I find myself avoiding the projects that make you do large numbers of swipes in one task because I know that increases the likelihood of encountering the issue before I can finish them. Less prevalent but no less annoying is that when you try to sign in with OpenStreetMap instead of creating a dedicated MapSwipe account from scratch, this app just hangs. It’ll open OSM in the browser, OSM will ask if you’r like to authorize MapSwipe, you click “authorize”, and then it opens MapSwipe and just… flashes the logo at you, over and over. I like the color-coded tapping system and the project system. When the app works, it feels incredibly rewarding and also even relaxing, but it currently doesn’t work consistently at all.

The app is fine, but it’s quite frustrating trying to get the down swipe to work. I end up just triple tapping each tile individually, which slows down progress. Would be nice if it allowed a little more zooming in. Even with low res, it could be helpful.
