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).

Paper Maps

Poster size Maps and normal sized paper atlases of custom areas can be printed:

  • See OSM_on_Paper for an overview and list of platforms and services for printing maps.
  • We suggest FieldPapers Paper Maps with grid for field survey or general navigation purposes.

Exporting OpenStreetMap data

See Downloading data for instructions on getting large scale map data. See Shapefiles if you need this format to export to GIS tools.

Offline Road Navigation with small devices

With the availibility of Small communication devices, Navigation Offline data proves to be very useful to the humanitarians deployed in foreign countries. We support the humanitarian NGO's using navigation data and invite them to give us feedback on the utilization of these devices in the context of field deployment.

  • See Software/Mobile for more information on using OSM in portable devices.
  • See also Mobile Mapping on LearnOSM.org for information on mapping in the field.

History of this Activation

Reactivity of the OSM Community

  • 1 March 2019 - After inquiries as to what HOT might be able to help with in regards to the situation in Venezuela, the Disaster Coordination Leads decided to go ahead and initiate an activation to help with the refugee situation growing in Colombia and launched a buildings mapping effort for the city of Barranquilla.


  • HOT Disaster Coordinators: Theo Andrae and Russell Deffner
  • OSM Colombia Lead(s): Fredy Rivera

Support Team

  • HOT Support Team: Tyler Radford, Rebecca Firth, David Garcia, Ralph Aytoun, Jorge Martinez Gomez

Effort made

  • In about 36 hours from publishing the Barranquilla Buildings project, 26 Advanced Mappers made nearly 20,000 changes to the map, including the addition of just under 3000 buildings
  • 72 hours after launching the response, 37 Advanced Mappers have contributed 5250+ buildings in Barranquilla, Colombia
  • 5 days from activation, 46 Advanced Mappers have contributed just under 10,000 buildings
  • 1 week into response 49 Advanced Mappers have made almost 100,000 changes to the map including almost 14,000 buildings (resultmaps.neis-one.org)
  • Just over 3 weeks into response (23rd March) 99 Advanced Mappers have made 352,288 changes to the map including 61,000 buildings.
  • At the time of archiving the project (28 October 2020) 195 contributors had mapped 407,882 buildings!

Available Imagery

Imagery availability is good in the area.

OSM Default Imagery Sources

DigitalGlobe Premium appears to be the most recent across Barranquilla. Bing you may find easier to trace if nothing has changed.

  • Bing provides a global imagery data source that is the 'default' Imagery available for OSM (default option in most editors).
  • DigitalGlobe provides a Premium global imagery source that should be reviewed as it is likely the most recent imagery in the area. It also has little to no offset with the existing mapping and is relatively cloud free.

Alternative Imagery Sources

How to add/use Alternative Imagery

  • In many cases better imagery is available than the default; when possible we set up a remote link directly via the Tasking Manager, so there is nothing to do, the iD editor and (as long as enabled) JOSM will automatically add the imagery.
  • Additionally, with JOSM, it's relatively easy to add special imagery if the license is appropriate for tracing into OSM. For more details see JOSM Imagery Help
