## MapSwipe Description
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.

## MapSwipe Reviews in United States

### ***** "Best ‘game’ that makes scrolling really helpful and productive"
MapSwipe. Best app that seems like a game but isn’t. SCROLL REAL MAPS IN REAL DISASTER AREAS. HELP FIND HOUSES TO SAVE LIVES. Many rural settlements aren't well-mapped. it matters: Local agencies and teams are coordinating search, evacuation, and aid delivery in real time. By volunteering just a few minutes swiping through tiles, you help build the settlement location data that lets responders target relief where it's actually needed — turning imagery into life-saving logistics. Join any of the Red Cross groups to help rescue teams. Indonesia earthquake. Botswana, Columbia. Many parts aren’t well documented. You can help.

### ***-- "Good Goal, Way Too Buggy"
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.

### ***-- "Swipe down is flakey, allow more zooming in"
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.
-- Daboodah, 2024-09-26

### ****- "overall great app"
honestly I rarely do reviews but this app is great if you want to do something quick but slowly make an impact. Some of the guidance tutorials can’t be really applied to what some projects are asking for, but definitely wish more people knew about this app. it’s one of the easiest ways I can volunteer online through quarantine and I really hope that this app will blow up and get even more people on the project <3
-- ellagbella, 2021-03-29

### ***** "Great Idea and Execution"
This is a really cool app, it’s good to use when you’ve got some time to sit or are just hanging out. It doesn’t need a very strong connection or a powerful phone to work, and looking for buildings on it gets kind of addicting! It’s an awesome idea to crowdsource this kind of stuff, and the app functions perfectly. It’s simple and easy and has a good tutorial, so you should at least give it a try.

### ****- "iPad Functionality is missing"
Love the app and the cause, the app is simple and quick to pickup.

Would like to see more optimization for the iPad or a potential standalone app with greater tools and functionality.
-- Hajdinak, 2020-04-23

### ****- "Great app. Need more guidance"
This is really fulfilling an important need. I would like more guidance on what is the shadow of a tree and what is a round building. Thank you!

### **--- "v1.1.0 does NOT work"
8/12/2016 v1.1.0 still does NOT work. Same as reported on 7/15/2016. 

7/15/2016 v1.0 does NOT work. Tap the app icon, get black screen, and then it quits. iOS 7.1.2 on both iPhone and iPad. Sent feedback but no response.
-- what8ever, 2016-08-13

### ***** "Good feel good app"
Simple app, look at arial photos and tap once if it has the desired features, can be home/hut, roads or "tracks" depending on the tasks, tap twice for a maybe or three times for bad image. So very simple. 

I would like better definitions of a "track" since I think that means a path, so lots of paths show up which could be animal tracks or maybe even stream beds. I worry I'm flagging too many tracks. 

I think it would be good to have a gallery of normal objects. I'm sure someone is highly skilled at this task already and could provide examples of say six hut styles to help make sure we know what the look like.
-- iolaire, 2016-07-17

### ***** "Love Idea, Small Bugs"
This is an awesome idea! There are some lingering bugs tho. If you adjust the iPhone text size in settings, part of the text in the app flows off of the screen and makes it unreadable. Keep up the good work!
