Sewage in Vistula on Sentinel-2 images
The plume of sewage flowing into the Vistula is visible in satellite images. On 28th August, at 11:56 a.m., the Sentinel-2 satellite captured the moment of sewage falling into water, four hours after the start of the emergency discharge procedure into the Vistula.
The Crisis Information Centre CBK PAN prepared a situational map showing the place of discharge based on the Sentinel-2 optical satellite imagery acquired on 28th August (the day of failure) and 31st August. The Sentinel-2 images have been pre-processed, and thanks to the use of a colour composition in unnatural colours, the sewage stream along the left bank of the river is visible.
In the following days, the Crisis Information Centre will monitor the availablity and quality of satellite images for this area and provide updated situational maps.
