Hi, (Sorry for writing in English on talk-co but I don't speak Spanish unfortunately).
== 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 Colombia. 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 : http://maps.itos.uga.edu/ArcGIS/services/GIST/CO_HOT/ImageServer/WMSServer?FORMAT=image/png&VERSION=1.1.0&SERVICE=WMS&REQUEST=GetMap&Layers=0&SRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox} * 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 : http://www.icrc.org/eng/resources/documents/interview/2012/mapping-interview-2012-04-05.htm Hope we will do even better this time ! I am available if you need any other information. Best Fred _______________________________________________ Talk-co mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-co
