Spatial outputs of temporal correspondence methods for Sentinel-2 monitoring of post-catastrophic landscape dynamics on Khortytsia Island (Ukraine)

This dataset contains the complete set of spatial classification outputs generated from a Sentinel-2 time series acquired over Khortytsia Island (Ukraine) between 22 March 2021 and 15 April 2026. The classification products were produced using six temporal correspondence methods: axis-distance, spectral ellipse distance (geometric), Euclidean distance, Mahalanobis distance, Linear Discriminant Analysis (LDA), and Random Forest. The archive includes classified GeoTIFF maps for each observation date, primary cluster maps, supercluster maps, temporal correspondence outputs, graph-based supercluster models, validation tables, temporal diagnostics, and additional intermediate products generated throughout the analytical workflow. These data support the reproducibility of the associated methodological study and enable independent comparison of temporal correspondence methods for monitoring post-catastrophic landscape dynamics following the 2023 Kakhovka dam failure.
