Remote HOT Activation in the Philippines for Typhoon Yolanda/Haiyan

The Humanitarian OpenSteetMap Team (HOT) has activated to provide geographic base data in areas affected by typhoon Yolanda/Haiyan in the Philippines. Currently we are supporting the active OpenStreetMap Philippines community and we have activated in conjunction with our partners at the Digital Humanitarian Network(DHN). For more information about what other DHN partners are doing please read their blog post about the activation. We are also working closely with United Nations Office for the Coordination of Humanitarian Affairs (UNOCHA) and the American Red Cross (ARC) to determine if they have mapping needs which we can help fulfill.


Here are OpenStreetMap related resources that may be useful to responders.

Since our preparation began two days before the typhoon's landfall we have mapped the following:

  • Merged 1,240 place names from GNS data
  • Mapped 29,845 buildings
  • Traced 3,036 residential landuse areas

If you are a response organization and have specific mapping needs please contact us at Over 100 people have helped contribute to OpenStreetMap in the affected areas during this time. To view the extent of where this information is being added Pascal Neis has created an activity map of the area.
