A mapathon taking place in an office


On Wednesday 8 th June 2017 we had a successful mapathon at CMAST with a live link to London and Safe house when they made 5000 changes to kulimi, 500 buildings, 200 km roads and had a great time.

If you would like to organize similar Mapathon at your office please get in touch!



You can now help us via MapSwipe app too!

Our project has now been set up on the MapSwipe app by the Missing MapsMany thanks to Gabor from Missing Maps who helped us do that!


If you don’t have access to a PC (or have just a few minutes standing in a queue or riding a bus or train!), you can still map on OpenStreetMap via MapSwipe! Just download the app on your Android phone or iPhone, and select the Prevent FGM: Singida, Tanzania 2 task:


It’s very simple after than – swipe through “screenshots” of satellite imagery and click on the tiles that have at least one building. (Click twice if you’re unsure!)

Don’t forget to save your progress, complete more tasks, level up… 

By doing that you will make it a lot easier for us to identify residential areas & extend the efforts of the Mugumu Safe House to fight FGM!


Have an old Android phone? Don’t let it go to waste

We have been running community training in rural Tanzania to get locals to map their own communities with the Maps.me app on their phones. The only problem is –  very few people in Tanzania have access to a smartphone.

But you can help

If you have an unused Android phone hidden away in your drawer, you can send it to us. We will freshen it up & donate it to selected community members in rural Tanzania who will use it to put their community on the map and train others.

If you are anywhere in the London area, you could contact Janet directly & deliver your phone this way. We could also collect phones personally in Lithuania & Tanzania, or you can just send it to us from anywhere in the world!

Please fill out this form if you’d like to donate a phone or contact us!

We are also starting a Community Change Agents program very soon, and even with the funding received from the Humanitarian OpenStreetMap Team, we still need phones more than ever.

Don’t let your old phone waste away! Donate it for a good cause – and ask your friends & relatives to do the same!

Crowd2Map has been awarded a HOT microgrant!

For the first time, Humanitarian OpenStreetMap Team (HOT) is running a microgrants scheme, and we are one of the 10 awarded projects!

Crowd2Map Tanzania is going to receive $5,000, which will enable us to buy phones and train local Community Change Agents in rural Tanzania. Community Change Agents will be able to organize mapping in their local regions. This will help us gather knowledge which would otherwise not be possible – locals will name villages, enter points of interest and otherwise support our efforts to build comprehensive maps of rural Tanzania on OpenStreetMap.

We hope that this program is going to allow us to further fight FGM, address issues related to land rights, microfinance, and youth entrepreneurship, and map as many as 346 villages.

Many thanks to HOT & their generous sponsors for this opportunity. Read this post to know more about the other grantees!

We are having a mapathon tomorrow for IWD! Join us

We are continuing to map the region of Tanzania where FGM is prevalent, and we are making a big mapping boom tomorrow, for International Women’s Day!

Mapping party will be held at Technarium, Vilnius (Lithuania), joined by satellite locations in the UK, Tanzania and elsewhere around the world!

We will be mapping this task: http://tasks.hotosm.org/project/2501

If you’d like to join us for some mapping on the day, just get in touch, or connect on the day via the links below:

Holding a remote workshop with Northampton University student group

Last month Egle (@seplute) held a mapping session over Skype with Northampton University student group. The students quickly got hooked on mapping, claiming that it was “really addictive”, and mapped a few hundred buildings in the hour or so of mapping! We had Rhobi join us to answer questions about FGM as well, and the students were really engaged.

Find some screenshots below & our slides are here: http://www.slideshare.net/seplute/crowd2map-northampton-university-mapping-session

FGM season started early

Anticipated for December, we have received word that the FGM season has started already in the Mara region of Tanzania. We are rushing to map two tasks that will help Mugumu Safe House workers to identify & reach villages at risk:



Please help & invite all your friends to do mapping!

All you need is a PC and a mouse. Here’s an excellent instructional video, and detailed PDF instructions on how to get started.

Remember – every bit of land mapped makes a difference. 

Here’s what we know about the affected girls so far:
