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 Area of Interest 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

  • OCHA Poster Map (A0)


  • MapOSMatic Salgar urban area

Poster size Maps and normal sized 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.

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.

New imagery with high resolution (20cm/px) is avaible thanks to Federación Nacional de Cafeteros.


Bing is the 'default' Imagery available for OSM (default option in most editors). The Bing imagery coverage for the area is good, alternative imagery sources may be provided in the Task Manager Jobs, and/or described below.

There are offsets in the area of interest for Bing imagery, please refer to this video to learn how to make proper adjustments


Mapbox provides a good alternative if there are clouds or just for a second view.

Iniciative undergoing

  • 21/05/2015:[Drone Aerial Pictures offer] Jorge Luis Rodriguez, Geodrone SAS Manager offer drone for aerial pictures, requires support for travel expenses. This is his message send to talk-co list: "Actualmente soy el gerente de una empresa de asesoría y consultoría en vehículos aéreos no tripulados, GeoDrone S.A.S, y queremos poner a disposición de la OCHA, OpenStreetMap, UNGRD, nuestros plataformas y equipo de trabajo, que comprende Drones o UAVs de tipo Ala fija, Multirotor, y personal calificado en las áreas de geomática, fotogrametría y percepción remota. Nosotros podemos destinar 3 personas de nuestro personal técnico, para el levantamiento de las imágenes aéreas junto con las plataformas necesarias, así mismo el post-procesamiento de la información que se adquiera en campo. Lo único que requerimos, es el apoyo por parte de ustedes en cuanto al desplazamiento y la estadía en el lugar de la zona afectada."
  • 22/05/2015: Thanks to Creative Commons Foundations support, transport is now possible from Medellín to Salgar, post-disaster aerial pictures are planned to be taken this weekend.
  • 23/05/2015: Task could not be acomplished because close of aerial space due President of Colombia visit. OSM Colombia community maintain focus and is looking for new resources for logistics to rerun.
  • 15/06/2015: Succesfuly around 15 Ha. of imagery were taken using UAV thanks to Geodrone SAS and Fredy Rivera from Querty. More aerial pictures to come.

Lessons learned: Predisaster imagery requires to map high elements as power/communication towers, so UAV flights could be better planned. Bests practices and firts mapping results will be shared at 16/06/2015 crisis coordination room, with aid and goverment institutions.
