2014 West Africa Ebola Response
Nowadays, anyone can consult free OpenStreetMap Online maps, Routing services or even bring the Map on their Smartphone. For crisis like this Ebola Outbreak, thousand of contributors from around the world digitize rapidly the data from Satellite imagery to support the humanitarian organizations that deploy in the affected countries.
Our goal is to contribute to humanitarian relief by providing rapidly a detailed and accurate map (i.e., road network, villages, buildings, etc.) to support the humanitarian organizations. These services help locate people at risk rapidly, and facilitate the delivery of goods and services to remote areas. The various epidemiological services also can use these maps to monitor the situation.
Pierre Béland and Andrew Buck are coordinating this OpenStreetMap Response to the Ebola Outbreak.
The OSM servers, Editing tools and Map and Export products let us offer a variety of free Map and Export services to the humanitarian community. The OSM community support to these Activations is also impressive. The Humanitarian OpenStreetMap Team assures the bridge between the OSM community and the humanitarians. We partner with various international organizations and take the responsability to map quickly various areas while the international organizations deploy in the field to respond to this epdidemy and support the local communities.
Jean-Guilhem Cailton, Blake Girardot, Mikel Maron and others support in various ways (ie. Imagery processing and servers, imports, learning material, etc). Others make outreach, organize mapathons, validate the work done, facilitate the progression of the new contributors.
CartONG is supporting MSF Switzerland for the Ebola epidemic going into Guinea, providing the GIS support. One person of the staff is deployed in Guinea. Bing imagery is not available in various areas where suspected cases of Ebola are reported. Pleiades-1A images were bought by CartONG for three towns. Airbus Defence & Space and Mapbox-DigitalGlobe also contributed with free imagery. The Humanitarian OpenStreetMap Team (HOT) has been activated to coordinate the mapping effort by OSM contributors.
The American Red Cross is supporting the International Federation of Red Cross and Red Crescent societies.
Starting in July, a new contact group was providing a liaison with the World Health Organization (WHO), The United Nations Office for the Coordination of Humanitarian affairs (UN-OCHA) and various specialists.
Starting in August, contacts were established with U.S. Centers for Disease Control (CDC) team.
Until the end of April, VISOV monitored suspected Ebola cases, identifying the various travel routes. This information is useful in various ways and helps us to identify which areas to map. See the Visov Map.
July 11, Cedric Moro created a new Map to monitor suspected cases.
Map and Data Services
OpenStreetMap offers an online map and spatial database that is updated by the minute. Various online maps are based on OpenStreetMap, including Navigation tools such as OSRM. Tools and services allow data extracts for GIS specialists, routable data for Garmin GPS, GPS navigation with smartphones and other device-compatible downloads. With an Internet connection, regular syncing is possible, because there is open access to the community-contributed data as it comes in. Also bulk with downloads of OpenStreetMap data are ideal for use offline. In addition, maps can be printed to paper, if needed.
Browse the Activation Area to get a feel for the data that is currently available. Different map styles, including a special Humanitarian style, can be selected on the right side of the screen. Though some data may not render (appear) on the online map, it can be exported from the underlying database for other uses requiring more detail(See export section below).
Large poster-size maps and letter-size paper atlases of custom areas can be printed:
- FieldPapers Paper Maps with grid for field survey or general navigation purposes,
- MapOSMatic Large Paper Maps with grid, street index and POI, good for command centers, hospitals, etc.

Custom Android/OSMAnd offline file
Install by copying to OsmAnd directory on your Android device.
With the availability of small communication devices, Offline data for navigation proves to be very useful for humanitarians deployed in foreign countries. We support the humanitarian NGOs using navigation data and invite them to give us feedback on the use of these devices in the context of field deployment. Daily updates assure that the most up-to-date data is available for downloads. With limited communication in a disaster region, it is recommended that users download data in bulk before traveling to these regions for offline use.
- This OSMAnd Tutorial shows how easy it is to navigate with OSMAnd.
- Copy OSMAnd files : Files downloaded are placed in the download directory. Move these files to the osmand directory. After you rerun OSMAnd, these files will be available.
- Copy Garmin GPS files : In general, you should rename the img file to gmapsupp.img and move it to the directory called Garmin. After restarting your GPS, you should see this new map.
Reporting map errors while traveling with OSMAnd
With OSMAnd, you can notify the OSM mappers of problems with the map.
- First enable the "Edit OpenStreetMap" plug-in in OSMAnd by going to "Settings" -> "Plugin-manager" and check the "OSM editing" plug-in.
- Go to the map view in OSMAnd, and long-press near the error you found
- Click on the balloon that pops up and select "Report an error in OpenStreetMap." (if this option doesn't show up, double-check that you enabled the right plug-in)
- Write a human-readable, preferably English message, explaining how to fix the error or what is wrong.
- When you get back to a location with Internet, you can upload the bugs to notify us. Go to "Settings" -> "OSM editing" -> "Locally saved OSM POIs/Bugs" and use the bottom-left button to upload all your bugs.
The bugs will appear on the map, and will be handled when a mapper sees them. The mapper will try to correct the error using your message and the aerial pictures available. Please don't ask questions, as we will probably not be able to answer them. But please describe what's wrong and how it should be.
A message like "This hamlet is called Petifu instead of Wari" will result in a correct map, while a message like "How is this hamlet named?" is unsolvable for us.
After a mapper handles (and hopefully solves) the bug, the correction will be available the next time you download the maps.

Tools, Adaptation and Services
OSM developers communicate over the Internet through various communication channels. In 2013 they implemented the new Humanitarian Map Style, a map more adapted to humanitarian actions. This map, hosted by OpenStreetMap of France, is integrated into various online map tools.
Two OpenStreetMap tools, the Tasking Manager and the JOSM editor, are essential parts of this activation. As new imagery is available, new jobs are added to the Tasking Manager. This tool has allowed HOT to coordinate efforts of mappers around the world. Some days there were more then 200 simultaneous mappers registered on the Task Manager and editing, mainly with the JOSM editor. Other online editors, such as OSM's ID and Potlatch 2 editors, also are used for less-intensive mapping. LearnOSM.org offers material to instruct beginners and more advanced mappers in these editors.
UNMEER Routing / Travel Time Tool
Andrew Buck and Pierre Beland are coordinating this activation. The request for activation first came from Médecins Sans Frontières (Doctors Without Borders). The HOT team coordinates with CartONG, American Red Cross, UN-WHO, UN-OCHA and the Digital Humanitarian Network. This coordination contributes to a quicker and more-efficient response, and assures that a range of map products and services are offered to the humanitarian organizations that operate in the region.
The HIU unit of the State Department (MapGive initiative), Airbus Defence & Space and Mapbox-DigitalGlobe collaborate by providing free aerial imagery.
Amadou Ndong assists with mapping parties in African communities. A support team of experienced OSM members coordinates local contributors through the #hot IRC Channel. Mapping contributions from around the world through the Internet are coordinated through the use of the HOT Tasking Manager. Each contributor is assigned a square, called a "task," to map. When a task is complete, the contributor marks it "Done" on the Tasking Manager, and more-experienced contributors check their work to assure its accuracy.
Jean-Guilhem Cailton is supporting imagery processing, and TMS server. User:russdeffner assisted in the coordination by creating and updating this wiki page on behalf of the coordinator team, now a team effort.
News about this activation for Ebola
In some parts of the world, OSM members are organizing "mapathons," events where mappers gather to learn about mapping and to tackle specific map tasks. Mapathons give members an opportunity to meet-like minded mappers and to learn how to contribute to OpenStreetMap. Other mapathons are more generic, not focusing on specific tasks or crises, but providing a shared experience of mapping while improving mapping skills.
Upcoming events are listed below. Please indicate date, group and location of the mapathon. Link to more details for these events.
- Aug. 22, 2014, MapGive and American Red Cross host a mapathon at the American Red Cross building, 430 17th St. NW, Washington D.C., 2-6 p.m.

Statistics about the Ebola Effort
The humanitarian workers operating in West Africa are facing a very difficult and stressful context. To respond adequately to this epidemic, they need detailed maps of the region. The OpenStreetMap community has accepted this responsibility, and, by the beginning of August 2014, more then 700 contributors from around the world had contributed, digitizing information from aerial imagery. locating villages, adding names to identify those villages, and tracing roads and buildings.
This activation has been in two phases. At the end of March 2014, three cities in Guinea were mapped rapidly. Later coverage was extended to areas in Sierra Leone and Liberia, close to the Gueckedou area in Guinea. With the extension of the epidemic at the end of June, HOT reactivated to respond to the increasing needs of the humanitarian field workers on the ground.
The table below shows the growth of both the number of OSM contributors and the number of modifications of objects in the OSM database since the beginning of this activation.
By the beginning of May 2014 478 contributors had participated and 2.2 million objects had been modified or created in the OSM database.
By the 8th of August, the effort passed 5 million objects modified and more than 8,000 places. There were 449,743 buildings traced. Note that 8,296 of these buildings are represented by a simple node because the imagery for these zones is not detailed enough to show the outlines of the buildings. This contribution was made possible by the work of 840 volunteers around the world participating remotely through the Internet.
1POIs do not include nodes with place and building tags.
2By Sept. 1, there were 11,769 buildings represented as nodes because the imagery in some areas is not detailed enough to trace the outlines of buildings. These are included in this building statistic.
The statistics on contributor activity take account of nodes, ways and relations that were created, modified or deleted.
The net effect of these contributions on the OpenStreetMap database is remarkable. In comparison with the OSMPlanet of early 2013, the net effect on the map as of August 15 for Guinea, Liberia and Sierra Leone is :
- 62,442 km of highways added from 21,597 (+289%)
- 15,124 km of waterways added from 16,000 (+94%)
- 11,162 Places added
- 505,372 buildings added

Below are video tutorials of the various steps to do GNS Imports using JOSM.
This YouTube playlist covers configuration of JOSM for doing GNS Name Import tasks and shows the basics of getting started and how to merge name nodes into OSM. You can watch them all in order or just skip around for any that look helpful.
Bing has greatly extended his imagery coverage over the last two years. But for the Ebola outbreak, their high-resolution imagery was not available for the three main towns we need to cover and the adjacent regions. The group CartoNG has purchased imagery on behalf of MSF-Switzerland for the three largest towns in the region. Task Manager jobs have been created for these towns, and they were mapped in 20 hours by our contributors, coordinating through the Task Manager.
Our secondary priority was to trace roads and locations of villages in the wider region. We started with a Landsat 8 image taken the 23rd of March. We also had some scattered Orbview 3 (from around 1990) for a very limited region.
Higher-resolution imagery was later obtained for free by Jean-Guilhem Cailton from Airbus Defence & Space. A new program by Mapbox/DigitalGlobe to offer free imagery to OSM also came to the rescue.
How to add to JOSM
It's easy to add special imagery to JOSM from the task manager jobs, where an imagery URL is provided within the task manager. Clicking the URL should trigger JOSM remote control to add the new imagery as a layer. For more details see OSM Tasking Manager/Setting up JOSM
Bing is the 'default' Imagery available for OSM (default option in most editors). The Bing imagery coverage is not complete for the Activation area, and alternative imagery sources are provided in the Task Manager Jobs, and described below.
Mapbox / DigitalGlobe
Mapbox / DigitalGlobe imagery now contributes to complete the Bing imagery coverage.
Imagery URL for JOSM:
These Landsat 8 layers were put online by Jean-Guilhem Cailton on OpenStreetMap-France server and show natural color in the "432" image and a traditional "false color" image in the 753 layer listed below:
Imagery URLs for JOSM:
- Natural colour:
- False colour:
Imagery URL for JOSM:
These Pléiades layers were put online by Jean-Guilhem Cailton on OpenStreetMap-France server
Imagery URL for JOSM :
According to the e-mail of Jean-Guilhem Cailton on the HOT mailing list:
"Airbus D&S has offered two Spot-6 images, with 1.5 m resolution, covering the areas around Kenema and Kailahun. They are available in "natural colors," and also with a near-infrared band (NIR), in these TMS layers (that also include the Spot-6 images that were previously offered):
These are URLs for JOSM, and you must accept the Astrium / OSM license (http://tasks.hotosm.org/license/6) before accessing them. Use source=Spot-6, Airbus
They can be used (along with other imagery sources) for the current priority need to locate villages and hamlets, and access roads and tracks, in the District of Kenema.
And also to complete these elements (settlements and access roads) in the area between Kailahun and Koindu where Bing is obscured by clouds.
0.5 m resolution images should be available soon to map the buildings in the towns of Daru and Kenema, which have lower priority."

- For the first step of this activation, the VISOV group has helped us to locate areas to map, following media reports on suspected cases. For this second step, Cédric Moro has setup a new Tracking Map of Ebola cases for Sierra Leone and Liberia.
- From MSF GIS Officer Field Office - 18-April /2014: "To all OSM-Hot teams, First of all and once again, we would like to send a big THANK YOU to every single one of you. Your work is a gift to us all in the field. Building-scale mapping for such an area is a huge help for our outreach teams, and for many expats newly arrived and needing a briefing on how the outbreak is evolving. Finding remote localities and access to them is often a race against time as a few hours can make a serious difference, not only for patients, but also to arrive in time to prevent new contacts to happen and keep the outbreak from spreading further. Cross-checking between local knowledge and OSM maps allows us to work much faster"
- From MSF GIS Field Office - 2-April 2014: "A big THANK YOU from the emergency team in Gueckedou and Macenta to all of you guys in HOT/OSM! Your work speed and quality was far beyond our expectations. MapsKits are already distributed to the field teams and received an enthousiastic welcome from our staff, both international and local. As people carry on fighting against Ebola, it is heart-warming to feel presence and support from the international mapping community. Thanks to everyone!"
