OpenStreetMap
I was putting together some facts and stats* on OpenAerialMap and the open drone imagery it hosts and thought it might be interesting / useful for OSM peeps as a key user group…
In case you don’t know, OpenAerialMap is a platform for making open imagery available to people that need it.
At HOT, we are working on a collaboration with communities in informal settlements in Sierra Leone as part of the Know Your City project led by Slum Dwellers International.
The remote mapping of the settlements is hard, even with the excellent drone imagery flown by OpenStreetMap Sierra Leone. The environment is really dense, roofs overlap at different heights and structures that look like one from the sky actually include multiple buildings.
However, we have found the use of 3d and 2d imagery renders in parallel to be a bit of a game changer for this mapping activity. The mesh produced from the drone images allows us to angle and tilt in a way that we can better see how roofs interact with each other, what height they are and even sometimes how buildings are divided inside. We think this has vastly improved the accuracy of what we are able to do remotely.
Activation: Libya Floods 2023
Activation Declared: Sep 14, 2023
Activation Concluded: Nov 9, 2023
Debrief Conducted by: Pete Masters, HOT, Activation Lead
The devastating events in Morocco (earthquake) and Libya (floods) happened within two days of each other on the 08 & 10 September 2023. Both have meant large scale destruction of infrastructure and thousands of tragic deaths and injuries.
OSM communities in both countries (OSM Maroc and OSM Libya), alongside partners, have responded and with huge support from mappers from the OSM community across the world.
The following diary entry is an update on a similar one from 18 September.
More than 2,500 OSM mappers have added data to support responders in Morocco. Two projects on the HOT Tasking Manager has so far been completed (mapped and validated) and there are four more available for mapping.

Approximately 1,600 mappers have so far contributed to both campaigns, creating ~220,000 buildings and ~5,000km of roads.
Validation teams at HOT and UN Mappers have been busy providing quality control and trying to keep up with the rapid pace of the mapping.
Following the earthquake in Morocco last night (08-09 Sept 2023), staff from HOT’s West and Northern Africa Open Mapping Hub and OSM Morocco agreed to launch an activation to support response efforts.
If you would like to support by mapping, please do. The first project is now on the HOT Tasking Manager and more will follow.
You can also keep track via the activation wiki page : 2023 Morocco Earthquake.
If you have questions or would like to engage, you can do so via the HOT slack or the OSM community forum.
Thanks in advance for your time and skills in support!
This OSM diary is an English translation of Yekastreet’s OSM diary post called Sobre el “Mapping Workshop 2023”. Translating and re-posting because I enjoyed it so much :D
Among the many kilometres of routes we have mapped in the seven years since Youthmappers started, our own journey as YEKAStreetMGA continues to surprise and please us the most. We have grown as a team, from our first mapathons in the barely equipped classrooms of the university, to the partnerships we are now forming with our local mapping networks. Design by design, we make the use of open data tools a little more accessible. Through methodological design (a term unthinkable for us in the early days), we have now transformed our first university meetings into structured processes to disseminate and share our knowledge with a new community of mappers.
What we have experienced as students, as women, in a socio-political context that routinely places us between non-functional institutionalism and the uncertainty of self-management in educational processes, reaffirms once again that teaching is a highly political act. Empowering. Essential in the construction of new models of society. And, in a country where making community is a crime, mapping and locating ourselves is in itself an act of humanitarian rebellion. Here we are, here we exist, more than planimetry and satellite rasters. We are vectors on the map, with direction and meaning. And our dedication and commitment to cultivating and growing the community in Central America overcomes the risks and dangers.
Central America yes, because when we speak of Latin America we make invisible the particular individuality of Central Americans, we exist between Mexico and South America, and although we share, we are indisputably different from the rest of Latin America in our struggles, way of life, needs and challenges.
In April, I asked OSM community members to help us out with a better name for the HOT unSummit (which too often was confused with something to do with the United Nations!)
We had more than 100 name suggestions, so thanks a million to everyone who put some thought into it!
The new name for the programme will be…
So I want to send a big thank you to Courtney Williamson for the suggestion - a token of our appreciation will be on the way soon!
We are working out how to make the actual programme better and will be re-launching it in the coming months. If you know of events (mappy and other) where you think there might be appetite for incorporating open mapping and OpenStreetMap for humanitarian and development purposes, please feel free to reach out (and thanks to those who have already done so!)
We know from the pilot HOT unSummit programme that we need a better name (too many people thought it referred to the United Nations!)
Can you help us think of one?
It need to encapsulate one, some or all of the following aspects…
Once we have a new name, we will update the branding and the next phase of the programme will relaunch in June.

Well, hello everyone. I’m Doctor Mehmet Faruk Uçum.
I am the responsible physician in the largest tent city in Kahramanmaraş the KAFUM tent city. It is also known as New Ataturk Park and Kahramanmaraş Fairgrounds.
Here, as the responsible physician, I provide coordination in terms of health, we have set up the family health tent and we continue to vaccinate there. I also do public health work in the field.
During this process, with my friends in the OpenStreetMap community and my friends in Istanbul, we worked together and as a result of this work, we created a map.
I used this map especially during the vaccination process to find out which tent was where, because we really lacked data in this regard. We didn’t know the location of the tents, or which number was where, so we were not able to navigate to the right tents.
Recently again, I have used it to inspect and verify alleged scabies cases within the tents. I have, for example, some tent numbers that are said to have scabies but some of them may be seen wrongly or it is possible that the wrong number is given to us but I found them on the map and took the necessary action.
In public health, we used it again to identify outbreaks… the focus of outbreaks, that is. After marking the tent numbers on the map, we determined which areas had problems, especially for acute gastroenteritis, for example. Again, if there is a problem with viral rash diseases tomorrow, this map will be used for isolation and quarantine activities.
Ruben Martin and I discuss recent highlights and what’s coming up in the humanitarian open mapping community.
Syria & Turkey earthquake response // Activations in Malawi and Ethiopia // International Women’s Day catch up // Bolivia YouthMappers // Mapping journeys to impact // Ruwa project completion // What’s coming up? // Mappy quote of the week
Syria / Turkey earthquake response: The Turkey / Syria earthquake activation continues to progress — tasking manager projects are being finished off and and the validation is catching up. ~ 9,000 mappers have contributed over 2 million buildings and more than 83,000 km of roads so far. We also published this blog to try and provide insight into where the data is going and what it is being used for…
There is also this brilliant testimony from Dr Mehmet on his use of OpenStreetMap data for public health programming in the tent cities where people displaced by the earthquake are housed.
Activations in Malawi and Ethiopia: Additionally, the OSM Malawi community has activated to support the data needs for responders following Cyclone Freddy in Malawi — you can support them with mapping, here. OSM Ethiopia are also still mapping in response to the drought and food crisis in Ethiopia, which is drastically affecting people in the region of Oromia — you can contribute here.
International Women’s Day: There was loads of stuff to catch up from from International Women’s Day this week, too… My recommendations…
Encourage you to watch and listen!

Syria / Turkey earthquake response // Community Working Group mentorship programme // OSM Ethiopia community-led activation // Community research on barriers to women’s participation in OSM // International Women’s Day // Month activites and events // Mappy quote of the week
Syria / Turkey earthquake response: The response to the Turkey Syria earthquake has continued, with more than 8,500 mappers contributing to the data.
The validation of the data is still a heavy task, and the validation team is working so hard to keep up with the volume of mapping. Please be careful with your mapping and make sure the data that you create and they review is as good as it can be! This video from Becky Candy should help you if you are new to mapping.
Also want to congratulate Said for receiving UN Mapper of the Month for his role in coordinating the data response in the days following the earthquake.
A week ago, my colleague Can (who works at HOT and is part of Yer Çizenler) got a message from Dr Çevik, a Turkish surgeon treating people injured by the earthquake in Turkey.
It said: On the first day I went to Rehaniya, when Google Maps was not working, Organic Maps guided us. The importance of such tools is enormous. Good luck to you, Can. 🔥 organic maps 🔥
Can asked him to explain and he did… You can find the video here and the transcript below.
Ruben Martin and I discuss the recent activities and what’s coming up for the humanitarian open mapping community.
Over the past few weeks, the OpenStreetMap community has mobilised in response to the devastating earthquake that hit Turkey and Syria. More than 7,500 mappers have contributed to the response so far, and 221 validators have validated over 5,870 tasks in Turkey alone — the contribution of this relatively small number of validators has been phenomenal, trying to ensure high data quality for the relief efforts.
Since 06 February when the first earthquake struck Turkey and Syria, more than 6,500 mappers have mobilised to contribute to the response through the creation and improvement of OpenStreetMap data.
On 09 Feb, I wrote a diary post about whether the OSM data being contributed by mappers and validators in Turkey and Syria was helping anybody. This one builds on that theme…
Below is a selection of maps and map products being used by responders that incorporate OpenStreetMap data (gathered through searching data sources on maps and data products on ReliefWeb, the MSF Geo Centre and through what people are reporting on the HOT disaster-mapping slack channel). Click through the links to explore the maps yourself…

Short update to the previous post on whether mappers are really helping anybody in a disaster situation…
CJ Hendrix from OCHA reached out and shared statistics on the downloads of all of the OSM datasets for Turkey, provided by HOT through HDX…
I received this question through the HOT feedback form today. Here is my response in case anyone else wants to know.
The short answer is yes, we think so - the tasking manager projects have been created based on requests from organisations who plan to use the data.
The long answer is that in the immediate aftermath, everyone is looking for resources, including data, but we get very little feedback initially as to who exactly is using it.
People and orgs are busy responding. This info usually surfaces a little later and we will update when it does. In previous disasters such as the Haiti earthquake in 2010, Philippines typhoon Yolanda in 2013, and Ebola outbreaks in West and Central Africa, we have observed that responding agencies often begin using the map data a few weeks into the response, after the initial rush to establish the basics is done. This is only possible if we start early, so that by the time responders need it the data actually exists.
One proxy we do have is that the downloads of OSM datasets provided by HOT through the HDX platform are spiking. There is a lag on the reporting (so latest numbers are from 06 Feb) but we do see them going up. HDX is a key data source for humanitarian responders.
Ruben Martin and I discuss the recent activities and what’s coming up for the humanitarian open mapping community.
Earthquake response in Turkey and Syria // The first OSM diary from State of the Map Tanzania // Thank you packs received by top performing validators // An interview with OSM Somalia // Advances in the OSM contribution decline analysis and research // OSM Malawi @ community working group // Mappy quote of the week
This is not ‘exciting’, but very significant… The open mapping / OpenStreetMap community have responded in numbers to support people affected by the earthquakes in Turkey and Syria.. Just yesterday, over 1200 people contributed to mapping tasks in Turkey. New projects have also been published for Syria. The response in Turkey is being coordinated locally by mapping NGO, Yer Çizenler, who are working to connect local partners with the data.
Sharing with you again some of the things that Ruben and I have been excited about, and some of what’s coming up, in the HOT community and across the humanitarian open mapping movement.
Things that have excited us this week…
Congrats to the HOT training working group who had an impressive 52 participants at the advanced JOSM training last weekend!
Chisom Okwuchi shared a lovely OSM diary of her experiences as a Community Working Group mentorship lead…
… and, the organising group for the mentorship program is now planning for the next phase and will be looking for mentors and mentees in the next few months!
Shout out to Kraan46, one of HOT’s global validators, who has now validated on 360 days out of the last year — an impressive feat and huge contribution!
Contribution timeline for Kraan46!
Kudos to OSM Uganda, who have established a new MOU with the Terego district on integrating OSM learning into schools.
I really like the ‘notathon’ concept, so just posting a translated version of AngocA’s original diary entry (which was in Spanish).
On Saturday 1 October 2022, a notathon was held, as is customary one week after the Latam meeting. This time it took place in Mexico, and was coordinated by BigBlueButton - OSMVideo, where several people participated.
This time DAMN-project was used to divide the areas. For the division of areas we filtered by only the notes created from the Maps.me application. This is the task of DAMN: https://client.damn-project.org/?area=2407
We showed how to use the JOSM plugin, which automatically downloads the notes, and this allows to work in several areas, without having to leave the editor.
In total 63 notes were solved, with participants mainly from Mexico (alex_mayorga, Mapeadora, Sandra, among others), but there were also attendees from Venezuela (risturiz), Argentina (Manuel Retamozo) and Colombia (AngocA).
