Hello All, >From a DigitalGlobe standpoint, our preference is to mark the imagery as >"Source=DigitalGlobe" as opposed to NextView. Again, just a preference and >obviously low in importance compared to the task at hand. Also, the >DigitalGlobe WV2 imagery available through Bing Maps should have similar/equal >horizontal accuracy (depending on the elevation data used, I'm assuming >SRTM90m in this case) as the imagery available through NextView (<3.5 m CE90 >Geolocation accuracy) . In the case of QuickBird, this will have a lower >accuracy (CE90 23m Geolocation accuracy) compared to WV2.

This imagery has now been "pan-sharpened" and is available online as Tile Mapping Service, on an OpenStreetMap France server (image processing was performed on a server donated with hosting by Fondation d'entreprise Free, using free software, Gdal and Orfeo toolbox). It is interesting to look at imagery from both dates, as water levels may be different in various places, and they do not cover exactly the same area. Access requires acceptation of NextView license, and it is requested that "source=NextView" be mentioned when the imagery is used for mapping. To check that you have accepted this license, please go through the "Workflow tab" on http://tasks.hotosm.org/job/303 (Aug. 11 imagery) and http://tasks.hotosm.org/job/304 (Aug. 8 imagery) to get the TMS URLs (in JOSM format). (OSM account required). The imagery has not been accurately positioned with ground control points. Please adjust its offset before using it for tracing, using, for example, available Bing imagery, or available GPS tracks. Séverin has already registered offsets for the August 11 imagery in the offset database, available through the imagery_offset_db JOSM plugin.

New HOT Tasking Manager jobs have been made from a check between the Formosat 2 August 8 &9 analysis made by UNOSAT<http://unosat-maps.web.cern.ch/unosat-maps/SD/FL20130806SDN/UNOSAT_A3_Khartoum_Floods_FS2_20130809_Landscape.pdf>, and NextView panchromatic imagery from August 11 (the situation in the hit areas did not improve fron taht time due to the heavy rains). This imagery is available through the TM jobs, once agreed the License Aknowledgement . Offset exist but have been informed in the offset DB pluging for JOSM: * Task Manager Job 303<http://tasks.hotosm.org/job/303> * Task Manager Job 304<http://tasks.hotosm.org/job/304> 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. All the information is accessible from here: http://wiki.openstreetmap.org/wiki/2013_Sudan_floods and the TM jobs themselves Thanks for those who have already participated and those who will join!

Hi, 19-Aug 2013 is the world humanitarian day [1] Within this initiative, we are proposing to join a remote mapping campaign targetting the most flooded areas of Khartoum (Sudan). Details on this crisis are available through Relief Web: flood report [2], sudan weekly report [3]. More info about the HOT response on the English [4] and French [5] wiki page for this disaster. 3 Jobs have been set on the HOT Tasking manager: - Task no 289 [5]: a few tasks are left with mapping of streets and buildings - Task no 292 [6]: neighborhoods located South East from the town where streets only have to be mapped in this first task. - Task no 293 [7]: neighborhoods located West from the River where streets/ roads only have to be mapped given the size of the area Thanks in advance for all of those who will be part of this mapping Best, Severin [1] = <http://worldhumanitarianday.org/fr> [2] = http://reliefweb.int/map/sudan/sudan-flash-floods-06-aug-2013 [3] = http://reliefweb.int/report/sudan/sudan-humanitarian-bulletin-issue-32-5-11-august-2013 [4] = http://wiki.openstreetmap.org/wiki/2013_Sudan_floods [5] = http://tasks.hotosm.org/job/289 [6] = http://tasks.hotosm.org/job/292 [7] = http://tasks.hotosm.org/job/293 ---------- Forwarded message ---------- From: Severin MENARD <[email protected]<mailto:[email protected]>> Date: Wed, Aug 14, 2013 at 6:05 PM Subject: Floods in Khartoum, Sudan To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Hi, The floods are still hitting Khartoum.

You can follow the current situation on khartoumflood.crowdmap.com. The Humanitarian Response is led on the field by UNDP. I just created a TM job for the most affected area: http://tasks.hotosm.org/job/289. Others will follow. I will also create a wikipage. Please map all the streets and building on the area in order to get the pre-crisis situation, on which damage analysis will be done.
