2013 Sudan floods
| Information about this intervention |
|
Early August 2013, Khartoum, the Capital city of Sudan, experienced extremely heavy rains that have turned into floods, houses falling, areas drowning, victims. This also causes problems of drinking water supply and sanitation. You can follow the current situation on this Crowdmap. The Humanitarian Response is led on the field by nafeersudan.com (Facebook NafeerInitiative). On mid-September, MapAction, member of the Digital Humanitarian Network like HOT, has deployed two HIM experts in Khartoum to support the information management in the recovery phase. Having direct partners in the field, users of the OSM data, is a real opportunity to get better understanding about the needs of baseline data provided by OSM. Map of the affected zone (uMAP). This wiki page is to coordinate remote mapping for HOT contributors around the world. |

Mapping Priorities
Remote Mapping, Khartoum
There are several Tasking Manager jobs which provide micro-tasks to mapping contributors.
First tasks have been made from Areas of Interest identified by the Dartmouth University (see the umap):
New tasks have been made from a check between the Formosat 2 August 8 &9 analysis made by UNOSAT, and NextView Digital Globe WorldView-2 imagery from August 8 and 11. This imagery is available through the TM jobs, once agreed the License Aknowledgement. Offset have been informed in the offset DB pluging for JOSM so please use it:
Areas to be mapped are popular, remote neighborhoods. Please map all the streets and buildings in the task area in order to show the pre-crisis situation, on which damage analysis will be done.
Identification of priorities and local facilities to support displaced people
If you are in contact with local NGO, or you have knowledge of the area, you can contribute to geolocate and describe various public facilities and shelters. Please report any established priorities expressed by the local NGOs to the HOT Discussion list. This will facilitate the coordination with the HOT contributors.
