> == Context ==
> 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 in North-West of
> The image is 50 cm resolution, comes from the WV2 sensor (Digital
> Globe) and was acquired the 12th of March 2011.
> The ICRC will use the image and the OSM tracing to work on a Water and
> Sanitation project.
> == What to map ? ==
> The ICRC is very interested in the landuse (buildings and natural
> features), but the roads can of course also be mapped !
> == How-to use the imagery ? ==
> 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.
> I would like to document this on the OSM wiki but the Wikiproject
> Colombia is in Spanish. Could someone from the Colombian community add
> this imagery in the wiki where relevant ?
> This workflow went well and efficiently in Walikale, Congo. You can
> read this article on the ICRC website talking about this collaboration
> Hope we will do even better this time !
> I am available if you need any other information.
