Mariupol Updated Building Damage Assessment Overview Map - Livoberezhnyi and Zhovtnevyi Districts

**UNOSAT code: CE20220223UKR** This map illustrates a satellite imagery based damage analysis within an area of interest (AOI) in the residential area of Mariupol City, Ukraine. Based on imagery collected on 14 March 2022 and 21 June 2021, analysts found that 773 out of 17,594 structures sustained visible damage in the AOI. This represents approximately 4% of the structures. Out of these, 62 are destroyed, 315 severely damaged, 321 moderately damaged and 75 possibly damaged. This includes 8 schools and 4 health facilities. This analysis is based on structures visibly damaged as of 14 March 2022 as seen in marginally degraded satellite imagery. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT).

**UNOSAT code: CE20220223UKR** This map illustrates a satellite imagery-based Rapid Damage Building Assessment (RDBA) of the Mariupolska Hromada, Ukraine. The RDBA divides the city into 500m x 500m cells, each of which is analyzed to determine whether or not there are damaged buildings inside the cell. Based on imagery collected on 26 March 2022, analysts found that 556 cells out of 3,456 sustained visible damage. This represents approximately 16% of the cells over the Hromada. Note that not all 6,456 cells include buildings. Numerous craters are also visible in the fields but were not taken into account for this analysis. This analysis is based on structures visibly damaged as of 26 March 2022 as seen in marginally degraded satellite imagery affected by precipitation, seasonality, and other limiting factors. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to United Nations Satellite Centre (UNOSAT).

**UNOSAT code: CE20220223UKR** This map illustrates a satellite imagerybased Rapid Damage Building Assessment (RDBA) in the North of Kharkiv, Ukraine. The RDBA divides the area of interest into 500m x 500m cells, each of which is analyzed to determine whether or not there are damaged buildings inside the cell. Based on imagery collected on 21, 22 and 23 March 2022, analysts found that 72 cells out of 1,866 cells in the North of Kharkiv sustained visible damage. This represents approximately 4% of the cells over the city. This analysis is based on structures visibly damaged as of 21, 22 and 23 March 2022 as seen in marginally degraded satellite imagery affected by precipitation, seasonality, and other limiting factors. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to United Nations Satellite Centre (UNOSAT).

**UNOSAT code: CE20220223UKR** This map illustrates a satellite imagery based Rapid Damage Building Assessment (RDBA) in Sumy City, Ukraine. The RDBA divides the city into 500m x 500m cells, each of which is analyzed to determine whether or not there are damaged buildings inside the cell. Based on imagery collected on 20 and 22 March 2022, analysts found that 5 cells out of 1,111 cells sustained visible damage. This represents approximately 0.4% of the cells over the city. This analysis is based on structures visibly damaged as of 20 and 22 March 2022 as seen in marginally degraded satellite imagery. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to United Nations Satellite Centre (UNOSAT).

**UNOSAT code CE20220223UKR** This map illustrates a satellite imagery based building damage assessment in the city of Kremenchuk, Ukraine. Based on imagery collected on 29 June 2022, the analysis showed 26 structures with visible damage. Out of these, 1 is destroyed, 7 severely damaged, 3 moderately damaged and 15 possibly damaged. Inset 1 shows a building identified as severely damaged on 29 June 2022. While no complete count of buildings for Kremenchuk is available, an open source dataset, which is visibly incomplete, indicates at least 19,209 structures in the area. This analysis is based on visibly damaged structures as of 29 June 2022, as seen in marginally degraded satellite imagery affected by light clouds and other limiting factors. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to United Nations Satellite Centre (UNOSAT).

**UNOSAT code CE20231007PS** UNOSAT's satellite-detected damage and destruction to buildings within the area of interest in the Gaza Governorate, Gaza Strip, based on an image collected on 15 October 2023 compared to an image collected on 10 October 2023 (partially clouded), and 10 May 2023 shows a total of 533 destroyed structures, 640 severely damaged structures, and 1273 moderately damaged structures, for a total of 2246 affected buildings as of 15 October 2023. The most affected area appears to be the one south of Ash Shuja'iyeh neighborhood (inset 1), with clouds covered on the 10 October 2023 image. Among the new affected structures, UNOSAT identified two school compounds, namely the Elnoor W Alaml School, moderately affected, and the Islamic University of Gaza, previously cloud-covered and now severely damaged. Additionally, UNOSAT identified 45 affected road sections, either by impact craters or by debris. This is a preliminary analysis and has not yet been validated in the field.
