Use of Landsat Satellite Images in the Assessment of the Variability in Ice Cover on Polish Lakes

Despite several decades of observations ice cover in Polish lakes, researchers have not broadly applied satellite images to date. This paper presents a temporal and spatial analysis the variability occurrence on lakes Drawskie Lakeland hydrological years 1984–2022 based data from Landsat missions 4, 5, 7, 8, 9. The range was determined value Normalised Difference Snow Index (NDSI) blue spectral band (ρλblue). determination extent adopted ρλblue values 0.033 0.120 as threshold values. covered 67 with an area 0.07 18.71 km2. A total 53 were analysed, 14 39 out which showed full partial cover, respectively. cluster permitted designation two groups characterised by approximate cover. obtained results analysed context morphometric parameters lakes. It evidenced that is surface lakes; their mean maximum depth, volume, length, width; height location above sea level. analyses subsequent scenes allowed for preparation maps probability permit complete its within each Monitoring individual well reference subject traditional offers new research possibilities many scientific disciplines focused these ecosystems.
