Help improve humanitarian responses worldwide from the comfort of your own phone

Humanitarian organisations can't help people if they can't find them. MapSwipe is a mobile app that lets you search satellite imagery to help put the world's most vulnerable people on the map.

MapSwipe, developed in support of the Missing Maps Project, allows users to remotely contribute to humanitarian missions. Users choose a task in a crisis prone part of the world, such as spotting villages at risk of a cholera outbreak in the Democratic Republic of Congo. They then swipe through satellite images of the region, tapping the screen to mark the location of settlements, roads, rivers, and other features.

This information is fed back to mappers, who build detailed maps that can be used in the field. At present, these mappers must spend days scrolling through thousands of images of uninhabited forest or rural desert in search of small, often remote communities. With MapSwipe, members of the public can donate their time to humanitarian organizations including Médecins Sans Frontières and the Red Cross, crowdsourcing the arduous process of locating the people who need their help. With this generous contribution from users like you, professionals on the ground can get straight to work delivering life-saving aid.

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.

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.

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
