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 (example) 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.

Accessing OpenStreetMap data

See Downloading data for instructions on getting large scale map data, or see the focused exports below:

Ready-made exports of areas mapped during this Activation are listed below, or can be found by searching for "#peruearthquake2019" in the HOT Export Tool. Currently available:

This map shows the extent of the export regions

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 for information on mapping in the field.
