HOT Red Cross mapping project 2012

The ICRC (International Committee of the Red Cross) is looking for some support from the HOT community to digitize on top of a satellite image they have acquired over the city of Tierralta. Frédéric Bonifas is a key contact point. The ICRC will use the image and the OSM tracing to work on a Water and Sanitation project.

The following is information from his mailing list post

What to map ?

There aren't really any roads left to map

The ICRC is very interested in the landuse (buildings and natural features)

How-to use the imagery ?

The image is 50 cm resolution, comes from the WV2 sensor (DigitalGlobe) and was acquired the 12th of March 2011. coverage map

To add the imagery in JOSM :

  • Open the preferences and go to the WMS/TMS tab
  • Click on the "+" at the bottom right to add the new imagery, a dialog window opens
  • At the top, give a name to the imagery, e.g. "Tierralta ICRC". At the bottom, in the "Imagery URL" field, paste this :
  • Click OK and the imagery is now available in the "Imagery" menu.
  • When you zoom in or out, you need to right-click on the name of the

imagery in the "layers" list and the click on "change resolution"

The source tag to use is "ICRC, DigitalGlobe 120311"

What comes next ?

Once a large part of the imagery is digitized in OSM, the ICRC team in Tierralta will use Walking-Papers to enhance the map with POIs and street names.
