This study systematically identifies and analyzes geometric distortions, specifically layover and shadow effects, in Sentinel-1 imagery across the Republic of Serbia. Тhe research quantifies these distortions caused by slant observation geometry. The primary contribution is a unique, publicly available spatial dataset representing distortion distribution for both ascending and descending orbits at a national scale. The analysis evaluates the magnitude of these effects across diverse topographic profiles, establishing a quantitative benchmark for assessing Sentinel-1 data usability.
The dataset generated and analyzed during this study is publicly available in the Zenodo repository at: https://doi.org/10.5281/zenodo.18380990 , and mirrored in the associated GitHub repository: https://github.com/milosbassa/radar_distorsion_masks
