About OpenStreetMap

OpenStreetMap offers an online map (and spatial database) which is updated by the minute. Various tools and services allow data extracts for GIS specialists, Routable Garmin GPS data, Smartphone GPS navigation, 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, with OpenStreetMap's bulk data downloads ideal for use offline. In addition, maps can also be printed to paper.

Browse the Activation Area to get a feel for the data that is currently available. Different map styles including an Humanitarian style can be selected on the right side, and some data may not render (appear) on the map, but could be exported from the underlying database (See export section below).

Exporting OpenStreetMap data

Visit the HOT Export Tool there are several exports in the area impacted by the floods.

History of this Activation

Reactivity of the OSM Community

  • February 12 - HOT contacts OSM Bolivia for needs assessment.

HOT Activates

  • February 12 - HOT receives a notification that UNOSAT will be responding and may need assistance.
  • February 13 - Gap in building data identified, first mapping project released.

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 - France, is integrated in various online map tools.

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. Online editors are also used for less intensive mapping. LearnOSM offers learning material for beginners and more advanced mappers.


This Activation is being coordinated by Blake Girardot and Russell Deffner of HOT.

Support Team

Support being provided by Nate Smith, Cristiano Giovando and Rebecca Firth of HOT.
