Typhoon Haiyan (Wikipedia), also known as Typhoon Yolanda, is a tropical cyclone that devastated the Philippines. It first made landfall at Guiuan, Eastern Samar on the morning of November 8, 2013, and then proceeded to Tacloban City (map), where a storm surge laid waste to much of the area. The typhoon then caused destruction in northern Cebu, Panay island, and northern Palawan before exiting the country towards Vietnam.

Jan 1st 2014, 1,670 voluntary contributors of the OpenStreetMap project from 82 countries have contributed to map for the typhoon Yolanda / Haiyan humanitarian response. They did this mainly from their home with their personal computer communicating and coordinating on the internet. The Humanitarian OpenStreetMap Team (HOT) acts as a bridge between the OpenStreetMap Community and traditional Humanitarian Responders.

OpenStreetMap offers an online map which is updated by the minute. Meanwhile various tools and services allow data extracts for GIS specialists, Routable Garmin GPS data, OSMAND, and other device-compatible downloads. With an internet connection regular syncing is possible with open access to the community contributed data as it comes in, but OpenStreetMap's bulk data downloads are ideal for use offline. Of course the maps are also printed to paper. Aid agencies such as the Red cross delivered poster-size maps to field teams.

HOT Updates

History of this intervention

  • Thursday 7th Nov: The day before the Typhoon struck Tacloban city, OpenStreetMap contributors started to map the city.
  • Sunday 10th Nov: We declared an official Humanitarian Activation, which indicates that this is the highest priority for our organization and asked others to help us.
    • We setup coordination with various actors including OCHA, the American Red Cross and the US State Dept Humanitarian Information Unit (HIU).
    • The International Charter 'Space & Major Disasters' also activated, the various imagery providers realigning satellites to obtain post-disaster imagery.
    • Our imagery specialists started to look for Imagery, adapt it and host it on servers for access by the mappers.
    • We planned a revised humanitarian mapping workflow with a tagging scheme for damaged buildings and infrastructures and adaptation of the various tools to deliver appropriate maps.
  • Monday 11th Nov : The European Commission released the first post-disaster imageries of Tacloban.
  • Wednesday 13th Nov : HIU delivers Post-disaster imagery from Digital Globe and the first Post-disaster Task Manager job is available for mappers to look at damaged buildings of Tacloban.


Reactivity of the OSM Community

  • Friday 15th Nov: More then 900 OpenStreetMap mappers have contributed to this project. In a week, they have modified more than 2,000,000 objects on the map.
  • Saturday 16th Nov: At the request of the US government, for humanitarian reasons, DigitalGlobe renders public for 30 days the pre and post-disaster imageries related to the Hayian typhoon.
  • Tuesday 19th Nov: Over 1,200 OpenStreetMap mappers have modified more than 3,000,000 objects for the project.
  • Sunday 24th Nov: Over 1,500 OpenStreetMap mappers have modified more than 3.8 million objects for the project.
  • Wednesday 11th Dec: Over 1,600 OpenStreetMap mappers have modified more than 4.5 million objects for the project.


Tools adaptation and services

The various OSM developers communicate over 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-fr, is integrated in various online map tools. For this activation, we decided to show the damaged buildings on this map and to better integrate the various paper maps in the humanitarian workflow. The developers responded quickly and we were able to deliver these maps 10 days after the typhoon.

The Tasking Manager and the JOSM editor are essential parts of this Activation. As new imagery are available, new jobs are added to the Tasking Manager. It 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. ID editor is also used for less intensive mapping. LearnOSM.org offers learning material for beginners and more advanced mappers.

  • Monday 11th Nov:
  • Wednesday 13th Nov:
    • Navigation Offline Data for Android smartphones : Experimental hourly updated Philippines map for OsmAnd available here: http://osmd.ch/haiyan/ (install by copying to OsmAnd directory on your Android device). With limited communications in the disaster region, it is recommended to download offline data before travelling to this region.
    • Paper Maps : Various field teams that start to deploy are requesting Paper maps. We recommend to people that travel to the disaster zone to print and bring paper maps with them and to download Geofabrik extracts of Routable GPS Garmin files and OSMAND offline data.

  • Friday 15th Nov: uMap Personal Online Map Service adds an option for Map overlays with Dynamic requests to external services like Xapi or Overpass. This lets extract various data from OSM (See example).
  • Saturday 16th Nov: Humanitarian Map Style is adapted for humanitarian actions. Revision is made for Damaged buildings (orange) and Collapsed buildings (red). This Humanitarian layer is integrated in various online maps. Red Cross and others are accessing the Humanitarian Map tile service hosted on OpenStreetMap-fr servers. See Harry Wood Sample Map describing how to add to an OpenLayers Online map.
  • Monday 18th Nov: 10 days after the typhoon, Humanitarian Map Style is available with tools such as
    • FieldPapers Paper Maps with grid for field survey,
    • MapOSMatic Large Paper Maps with grid, street index and POI and
    • Osmose Validation / Correction tool.

With the Humanitarian style integrated, these three tools show the buildings damaged or destroyed. Better field survey and quality control is possible. We have produced in coordination with the Red Cross detailed maps that help identify infrastructure at risk and severely affected areas. Navigation Products extracted from the OSM database are also facilitating field teams road navigation in the region. Updates to the OSM database are immediately reflected on the maps and in the various Data extracts available.

Coordination

Andrew Buck, assisted by Maning Sambale and Pierre Béland, are coordinating this activation. We coordinate with the Red Cross and the Digital Humanitarian Network. Regions requiring mapping are coordinated through the use of the HOT Tasking Manager.

Support Team

Contributors from 82 countries collaborate to this Activation through internet. In such a context, various communication medias are used to coordinate. The support team communicates via the irc://irc.oftc.net #hot IRC channel. You can join the Support Team and the Coordinators on the IRC for discussions or help for mapping. You can also talk with other mappers or the support team by installing mumble and connecting to our server talk.hotosm.org

Public e-mail communication among HOT Team members can be found at Humanitarian OSM Team (HOT) Mailling-List. The first posting was "Preparations for Typhoon Haiyan" which appeared the day before landfall. Thereafter, the majority of posts to the e-mail list in November 2013 related in some way to the typhoon response.

Effort made

With the dispersion of the population in numerous islands and with the extent of the damages, Up-to-Date maps is an essential aspect of the management of this crisis. Tremendous efforts have been made by the OpenStreetMap community. The developers are adapting tools to provide up-to-date maps rapidly to humanitarian field workers. Hundred of contributors are also tracing over Satellite imagery to update continuously the maps.

Mapping response

The first week of this Activation, intense work was done by OSM contributors to update the base map for the affected zones using pre-Disaster Imagery (mostly Bing Imagery). From, Nov 14, Post-Disaster imagery from various providers started to be available. As these imagery arrive, new tasks will be added. Your help is welcomed for remote mapping and is essential for a rapid response and the success of this operation.

Tacloban City, Leyte (population: ~220,000) has been hit hard. Important Relief efforts will be localised there. New reports indicate international and local aid workers are beginning to arrive. We have already pretty much mapped every building in the city based on pre-typhoon Bing imagery (second-pass validation is always welcome mind you). Other mapping areas are laid out in various task manager jobs :

Available Imagery

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

Bing is the basic Imagery available for OSM. It provides high-res Imagery for most of the affected areas. However, other high-res imageries are sometime used for areas where more recent imagery is provided.

DigitalGlobe

In support of Operation Damayan, the US Government has requested that DigitalGlobe imagery be temporarily released and licensed to the public for humanitarian purposes.

This imagery is available under the NextView licence for 30 days, starting on Nov. 16, 2013. (It appears that this period of time could be renewed, depending on operational need, according to this tweet).

To use it for mapping, go to http://tasks2.hotosm.org/job/1003 , Workflow tab, read and agree to the NextView licence, and click on the given wms: URL in the Workflow tab.

(You may also have to copy/paste the wms URL manually into JOSM preferences)

Humanitarian Information Unit set up a service for North Cebu post-disaster image as TMS: http://hiu-maps.net/hot/1.0.0/cebu-post-flipped/{zoom}/{x}/{y}.png

TMS and WMS services for priority areas are also hosted on OSM France servers, under NextView license (unlimited in time), as described in these posts: https://lists.openstreetmap.org/pipermail/talk-ph/2013-December/004884.html

https://lists.openstreetmap.org/pipermail/talk-ph/2013-December/004896.html

CNES - Astrium

For the first time in the history of the International Charter Space and Major Disasters, CNES and Astrium, producer and distributor, released the Pleiades images acquired within the Charter under a free license.

The raw imagery files are available online on a public ftp server, for whichever innovative use you may see fit to support disaster and recovery efforts: ftp://ftp.astrium-geo.com/Philippines/

You can for example print them on paper for wall posters, or for quick paper maps to walk around damaged areas with a view from the sky, to go navigate in the field on a road network riddled with fallen trees, etc, etc, etc...

Tacloban Pleiades-1 image was used for example to produce post-disaster high resolution imagery atlases of Tacloban City, Palo and Santa Fe municipalities, with a pdf map for each barangay or village, on request from responders in Tacloban who wanted to plan the relief work of NGOs: http://wms.openstreetmap.fr/philippines-yolandaph-pleiades/


Esri hosts web services: http://disasterresponse.maps.arcgis.com/home/item.html?id=3f6a9b3cf73642c28071b67efec4cd04

Enhancing Bing Imagery

Since the Bing Imagery is partly low contrast you might wish to enhance it. An ancient JOSM binary exists with which you can do so, but a lot of plugins don't work with it anymore - buildings-tools amongst them. Go here for details: Enhance Imagery.
