Satellite detected water extents between 03 and 07 November 2021 over South Sudan

**UNOSAT code: FL20211015SSD**  This map illustrates cumulative satellite-detected water using VIIRS in South Sudan between 03 to 07 November 2021 compared with the period between 20 to 24 October 2021. Within the cloud free analyzed areas of about 630,000 km2, a total of about 33,500 km2 of lands appear to be affected with flood waters. Water extent appears to have decreased of about 2,700 km2 since the period between 20 to 24 October 2021. Based on Worldpop population data and the detected surface waters, ~935,000 people are potentially exposed or living close to flooded areas.

Geodata of Elevation Map of Kalobeyei, Turkana County, Kenya

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.

Geodata of Update: Al Zaatari Refugee Camp, Mafraq Governorate, Jordan

This map illustrates satellite-detected shelters and other buildings at the Al Zaatari refugee camp in Mafraq Governorate, Jordan. As of 26 April 2015 a total of 29,231 shelters were detected as well as 1,966 infrastructure and support buildings within the 534.4 hectares of the camp. Between 11 November 2014 and 26 April 2015, a total of 2,676 shelters closed or were moved, and a total of 2,723 shelters were constructed, and the number of shelters has thus decreased by about 12 since the previous UNITAR/UNOSAT assessment. This indicates an approximate 0.04% decrease in the number of shelters between 11 November 2014 and 26 April 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. 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.

Geodata of Snow cover extent over West Bank, Israel, Jordan, Lebanon and Syria

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.

Potentially affected area by volcanic eruption effect of the 4 Dec 2021 in Java Province, Indonesia as of 10&11 Dec 2021

**UNOSAT code: VO20211205IDN**  This map illustrates the potentially affected areas by Lahar and Pyroclastic density currents (PDCs) including geological information of Mount Semeru, Java province, Indonesia as detected by satellite images acquired after the eruption of the Mount Semeru on 4 Dec 2021. UNITAR-UNOSAT analysis used Pleiades images acquired on 10 & 11 Dec 2021 to estimate the affected area by Lahar and Pyroclastic density currents. Within the analyzed area, about 3,220 ha appear to be affected. 

Based on Worldpop population data and affected area by Lahar and pyroclastic density currents, about 8,400 people are potentially exposed or living close to pyroclastic density area.

In addition, base on Esri 2020 Land Cover, potentially affected in tree area ~2,100ha, scrub/shrub area ~ 400 ha, cropland ~ 165 ha, built area ~ 140 ha.

Important note: Pyroclastic density currents (PDCs) are perhaps the most hazardous events to local areas during explosive volcanic eruptions.

Satellite detected waters over Cochabamba department, Bolivia

This map illustrates satellite-detected standing water over the Cochabamba department in Bolivia, as of the 10 February 2018, following the heavy rainfalls that caused severe flooding in the area. The analysis was conducted using Sentinel -1b and Radarsat-2 images as of 9, 10 and 12 February 2018 respectively. UNITAR-UNOSAT identified in the analyzed area of the Cochabamba Department, around 1,300 Ha of land seem to be inundated, which almost 35% ,450 Ha, are in the province of Punata. It is likely that flood waters have been systematically underestimated within built-up urban areas because of the special characteristics of the satellite data used.
