Multi-Temporal Sentinel-2 Land Cover Dataset for Cianjur Regency, Indonesia (2021–2023)

This dataset provides a multi-temporal land cover dataset derived from Sentinel-2 MSI Level-2A imagery for Cianjur Regency, West Java, Indonesia. The dataset covers three observation periods representing pre-earthquake (2021), earthquake-year (2022), and post-earthquake (2023) conditions associated with the 21 November 2022 Cianjur earthquake. The dataset includes annual cloud-masked Sentinel-2 composites at 10 m spatial resolution, six spectral index layers (NDVI, EVI, mNDWI, NDBI, NDBaI, and NBR), training and validation reference datasets, classified land cover maps in raster and vector formats, land cover change products, and classification accuracy assessment outputs. Land cover classification was performed using a Random Forest algorithm implemented in Google Earth Engine and categorized into seven dominant land cover classes. All dataset components are provided in standard geospatial formats (GeoTIFF, Shapefile, and GeoJSON) and are accompanied by supporting documentation to facilitate transparency, reproducibility, and reuse. The dataset is intended to support land cover change analysis, environmental monitoring, disaster impact assessment, and geospatial modeling in earthquake-prone regions.
