  • This map illustrates satellite-detected areas of IDPs in the UNMISS Malakal base as seen by the WorldView-2 satellite on 26 September 2015. Imagery acquired on this date shows that the IDP camp extent has increased compared with the previous UNOSAT analysis. Imagery also shows that shelters installed outside the UNMISS base are still increasing. Note that IDP occupied areas include improvised shelters and, in some cases, administrative support and other structures which gives a total number of 536 Camp infrastructure buildings and 7,791 Shelter structures. As can be seen from the imagery, PoC 1, 2, 3 and 4 are the initial or old Protection of Civilians (PoC) zones, Sector 1 and 2 are the new PoC extensions while Sector 3 is a contingency area mainly for administrative structures and Sector 4 is void of any infrastructure at the moment. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

  • This map illustrates satellite-detected shelters in the area of the Rukban border crossing on the Syrian- Jordanian border. Using a satellite image collected by the Deimos-2 satellite on 24 April 2016, UNOSAT located 6,104 probable shelters in the open desert along and near the Jordanian side of the border about 25 kilometers southwest of the Al Waleed border crossing. This is an 81 percent increase in apparent shelters visible compared to the previous UNOSAT analysis done using an image collected 03 February 2016. Due to the very small size, the irregularity of the shelters and the cloud cover it is likely that some shelters may have been missed in this analysis, or some shelters were included erroneously. In addition, the border in this area is poorly surveyed and in dispute and has thus been depicted as a zone for the purposes of this map. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.
  • This map illustrates satellite-detected shelters and other buildings at the Al Zaatari refugee camp in Mafraq Governorate, Jordan. As of 12 October 2015 a total of 26,963 shelters were detected as well as 2,130 infrastructure and support buildings within the 534.4 hectares of the camp. Between 26 April 2015 and 12 October 2015, a total of 4,310 shelters closed or were moved, and a total of 2,296 shelters were constructed, and the number of shelters has thus decreased by about 2,268 since the previous UNITAR-UNOSAT assessment. This indicates an approximate 7.76% decrease in the number of shelters between 26 April 2015 and 12 October 2015. This is a preliminary analysis and has not yet been validated in the field; structure locations subject to a spatial error margin of +/- three meters.

  • This map illustrates topographic features in the planned Kalobeyei site, Turkana County, Kenya using a Digital Elevation Model derived from imagery with 1m resolution. UNITAR-UNOSAT built water levels scenarios that represents the potentially affected areas along the modelled stream network assuming a static raising of waters of 1 meter, 2 meters and 3 meters. Streamlines and static water levels has been extracted from a Hydrologically Conditioned version of the DEM derived from WorldView-2 Imagery with 5 m resolution. The model shows spatial distribution of potential water levels in the basin based on the elevation extracted from the DEM but does not represent a current flood scenario. This is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.
  • Summary: A total of 324 spatially distinct IDP shelter concentrations were identified as of 24 November 2013 within Mogadishu, representing a decrease of 56 IDP sites since the last UNOSAT analysis which used an image from 13 June 2013. An estimate of the total number of IDP structures located in Mogadishu indicates a minimum figure of at least 55,000 mostly informal shelters. The number of IDP camps has significantly reduced in multiple areas of Mogadishu. This report is the sixth in a series of IDP analyses done by UNOSAT since 2011 and is based on a time-series analysis of shelter concentrations within the city of Mogadishu using multiple satellite images acquired between 30 March 2011 and 24 November 2013. This assessment has not yet been validated in the field. Please send feedback to UNITAR/UNOSAT.
