    This map illustrates satellite-detected areas of destruction in the town of Leer as seen by the GeoEye-1 satellite on 2 February 2014. UNOSAT analysed all structures in the town to verify reports of damage and determined that a large portion of the town has been destroyed, primarily by fire. A total of 1,556 burned or otherwise destroyed structures (including tukuls, other residential structures, and outbuildings) were identified throughout the town, as well as 26 destroyed commercial structures. Several active structural fires and smoke plumes (see inset) are also visible as of 2 February, as are indications of looting. This is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
  • This map illustrates potential satellite-detected inundated areas and water south of Sar-E Pol city, Afghanistan. UNOSAT analyzed imagery from the KOMPSAT2 satellite collected 05 May 2014 in response to heavy rainfall occurring on 23-24 April 2014. UNOSAT extracted areas of water and inundated soils to indicate likely flood affected lands. This map includes both permanent water bodies, such as streams, and potential flood waters together due to limitations in source data. It is likely that flood waters and inundation have been systematically underestimated along highly vegetated areas and within built-up urban areas because of the special characteristics of the satellite data used. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR /UNOSAT.

  • This map illustrates the camp for internally displaced persons (IDPs) in the UNMISS base at Juba airport as seen by the WorldView-1, Pleiades and WorldView-2 satellites on 30 January, 19 January, 7 January 2014 and 28 December 2013. As of 28 December 2013 a significant portion of the airport was used by IDP?s shelters, occupying approximately 7 ha. Imagery acquired on 30 January 2014 shows that the total area of IDP?s occupies about 9 ha, compared to the 7.9 ha detected on 7 January 2014. Note that IDP occupied areas include improvised shelters and, in some cases, administrative support and other structures. Analysis indicates the extent of the IDP camp on 30 January is largely unchanged from the previous analysis done using an image from 19 January 2014. 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 areas of IDP shelters in M Poko Airport in Bangui, Central African Republic. Using satellite images acquired on the 28 December 2013 by the QuickBird satellite, UNOSAT reviewed the airport grounds and delineated 22.3 ha of area where IDPs are living in shelters and in the open. Imagery acquired on 20 January 2014 shows that the IDP camp extent has increased compared with the previous UNOSAT analysis. The total area of IDPs occupies 26.8 ha as of 20 January 2014, although imagery shows areas where terrain has been cleared and shelters have been relocated. Note that IDP occupied areas include improvised shelters and, in some cases, administrative support and other structures. An area of expansion is also visible in the image as of 20 January 2014, indicating preparations are underway to accommodate increased numbers of refugees in the near future. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

    This map illustrates probable IDP shelter in Kismayo, Somalia as seen in satellite imagery collected by the WorldView-1 satellite on 5 March 2014. In this area UNOSAT located 1,969 shelters in 57 apparent IDP settlements. However, poor image quality, density of shelters, and varied construction material introduces significant uncertainty into this analysis. The IDP settlement areas were also compared to an image from 11 August 2013 collected by the Pleaides satellite to give indications on whether settlements were new, had closed, or were increasing or decreasing in size. 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 areas of destruction in the town of Malakal as seen by the WorldView-2 satellite on 18 January 2014. UNOSAT identified a total of 515 destroyed residential and related structures and a total of 58 warehouse or commercial structures were identified throughout the area analyzed, with the heaviest damage in the downtown area and along primary roads bordering the town. In addition, multiple indications of looting are evident in the warehouse area and in residential areas along the southeast edge of town. 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 urban areas that were affected by flash flooding along the Matanikau River in Honiara, capital city of the Solomon Islands. Analysis was conducted using a Resurs-P panchromatic image acquired the 08th and the 13th of April 2014. Traces of waters can be seen in urban areas along the Matakinau River and ~ 100 houses seem to have been washed out and/or flooded by the flash flooding event in the identified areas. A bridge in the Chinatown neighbourhood appears to be totally destroyed, however the main bridge further north seems intact. The exact limit of flood affected zones is uncertain because of the sensor characteristics of the satellite data and the nature of the vent (flash flood). This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

  • Este mapa representa áreas inundadas detectadas por satélite en los alrededores de la ciudad de Trinidad, en el departamento de Beni, Bolivia, usando datos de RISAT-1 obtenidos el 18 de Marzo de 2014. Las signaturas de agua han sido detectadas principalmente en los alrededores de la ciudad, no habiéndose observado masas de agua en el interior de la misma. Es probable que la extensión de las inundaciones haya sido infra estimada a lo largo de las zonas construidas, dadas las especiales características de la imagen de satélite utilizada. Este es un análisis preliminar que aún no ha sido validado en el terreno. Por favor envien sus comentarios a UNITAR /UNOSAT.
  • This map illustrates satellite-detected areas of destruction in the town of Bor as seen by the WorldView-1 satellite on 19 January 2014. UNOSAT identified a total of 1,962 destroyed residential and related structures and a total of 93 warehouse or commercial structures were identified throughout the area analyzed, with the heaviest damage in the downtown area of government buildings. The destroyed structures comprise an estimated 8.4% of the total number of pre-conflict structures in Bor. This analysis covers only the period from 25 December 2013 to 19 January 2014 and damage occurring before that time may not have been identified. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
  • This map illustrates locations of destroyed structures in Bossangoa, Central African Republic. Using a satellite image acquired 28 February 2014 and compared to images from 22 January 2014 and 5 December 2013, UNOSAT reviewed the town of Bossangoa and surrounding areas to locate signs of destroyed structures. A total of 1,234 destroyed structures were located in the area, though structures marked as destroyed on 5 December are classed as "probable" due to the lack of a previous image for comparison. Some of the destruction detected in the 28 February 2014 image was likely a result of burning given the blackened structural remains visible in the imagery. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

    This map illustrates the refugee camp currently under construction in Al Azraq, Jordan using an image collected by the WorldView-2 satellite on 28 December 2013. As of 28 December 2013 a total of 3,174 structures were detected in the camp, 2,431 infrastructure and support buildings and 743 tent structures. Preparations are continuing so as to accommodate additional incoming refugees. The previous analysis done by UNOSAT using an image from 14 September 2013 detected a total of 2,689 infrastructure, support buildings and shelters. This is an increase of approximately 18%. Paved and unpaved roads have likewise increased significantly and define the transportation network in and around the camp. Water and sanitation services are also under development in multiple camp zones suitable for supporting thousands of proximate shelters. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

    This map illustrates water bodies at the Tokwe Mukorsi Dam, Masvingo Province, Zimbabwe, as detected by TerraSAR-X on 11 February 2014. The flooded area above the dam has greatly increased due to recent heavy rains and currently encompasses about 2,300 ha. Using a WorldView-1 image acquired on 2 January 2012, UNOSAT located a total of 751 structures in 143 homestead locations that would be submerged by the current flood water extent. It is likely that flood waters have been systematically underestimated along highly vegetated areas along main river banks because of the special characteristics of the satellite data used. This analysis 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 7 January 2014 a total of 28,093 shelters were detected as well as 1,735 infrastructure and support buildings within the 531.8 hectares of the camp. Between 30 September 2013 and 7 January 2014, a total of 4,982 shelters closed or were moved, and a total of 6,868 shelters were constructed, and the number of shelters has thus increased by about 2,171 since the previous UNITAR/UNOSAT assessment. This indicates an approximate 8.4% increase in the number of shelters between 30 September 2013 and 7 January 2014. 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. Shelters grouped under plastic sheeting were estimated by average household size and may be a source of error. Please send ground feedback to UNITAR/UNOSAT.
