    This map illustrates satellite-detected areas of flood affected land as detected in satellite imagery acquired by the TerraSAR-X satellite on 09 August 2014 in Khartoum State, Sudan. The area surrounding Khartoum City and Umdurman was inundated by floods caused by heavy rains. Areas to the South of Umdurman seem to have been flooded and many other areas including Umdaba and East Nile seem to be affected by varying levels of water and saturated soils. The flooded area over Khartoum city has decreased slightly since the previous analysis using an image from 8 August 2014. It is likely that flood waters have been systematically underestimated along highly vegetated areas along main river banks, and within built-up urban areas because of the 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 extent of the snow cover caused by the storm "Huda" that moved through the Middle East region striking Lebanon, Jordan, and the West Bank from about 7-12 January. This analysis was based on satellite imagery collected by the MODIS sensor on the NASA Terra satellite on 12 January 2015. As seen in the imagery the snow has covered a very extensive part of the Lebanon and Syria. Due to cloud cover present on the imagery an extensive portion of the area of interest could not be analysed. This is a preliminary analysis and has not yet been validated in the field.

    This map illustrates satellite-detected shelters and other buildings at the Al Zaatari refugee camp in Mafraq Governorate, Jordan. As of 06 July 2014 a total of 29,982 shelters were detected as well as 1,880 infrastructure and support buildings within the 534.4 hectares of the camp. Between 06 April 2014 and 06 July 2014, a total of 4,257 shelters closed or were moved, and a total of 2,774 shelters were constructed, and the number of shelters has thus decreased by about 1,298 since the previous UNITAR/UNOSAT assessment. This indicates an approximate 4.1% decrease in the number of shelters between 06 April 2014 and 06 July 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.

    This map illustrates probable IDP shelters in Kismayo, Somalia as seen in satellite imagery collected by the WorldView-1 satellite on 3 May 2014. In this area UNOSAT located 2,952 shelters in 64 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 05 March 2014 collected by the WorldView-1 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 landslide damage in the village of Ab Barek, Badakshan, Afghanistan. Following heavy rains in the region, a landslide partially buried Ab Barek on 2 May 2014. Using a satellite image acquired 5 May 2014 by the WorldView-2 satellite, UNOSAT delineated the landslide area. In addition, areas of IDPs, relief operations, and water pooling due to the landslide are indicated as of 5 May. The 5 May 2014 image was compared to an image from 7 June 2013 in an attempt to determine how many structures were buried, and a total of 87 such structures were located. However, between 7 June 2013 and the occurrence of the landslide Ab Barek had changed and grown considerably, and thus its possible additional buried structures exist which are not identified in this analysis. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
