192 Large Scale Coastal Erosion Monitoring From Sar Imagery Over A 25 Years Time Span

192 Large Scale Coastal Erosion Monitoring From Sar Ima Mélissande machefer isardsat. Landsat images have been employed to assess shoreline changes along the eastern coast of ghana on a large spatial scale (lamptey et al., 2022; puplampu et al., 2023). the primary scope of the present work is to present a novel methodology for identifying and quantifying erosion and accretion zones, by leveraging the potential of sar data from.

Pdf Sea Level And Coastal Erosion Require Large Scale Monitoring The size of the observed changes can differ strongly between coastal stretches. the length of cross shore land erosion or active zone accretion exceeds 50 m in about 13% of the transects, while. More specialized tasks in coastal science can leverage these large datasets, through image premasking, preclassification, transfer learning, and so forth, but ultimately more powerful data driven models will inevitably require more specialized labeling in support of specific coastal science or monitoring objectives (e.g., seale et al. These space observations have largely improved our understanding of sea level variability, and have allowed a precise monitoring of sea level rise, with a global mean rate of 3.35 ± 0.4 mm yr and an acceleration of 0.12 ± 0.7 mm yr 2 over 1993–2017 (wcrp global sea level budget group 2018, ablain et al. 2019). It investigates remote sensing's capability to assess coastal ecosystems, follow land use changes, monitor shoreline dynamics, and aid in disaster response. the research emphasizes remote sensing's vital role in analyzing the effects of climate change, sea level rise, and human activities on coastal habitats.
