Unsupervised Automated Remote Sensing Monitoring of Crop Lodging for the Entire Pre- and PostDisaster Process

This dataset supports the study “Unsupervised Automated Remote Sensing Monitoring of Crop Lodging for the Entire Pre- and Post-Disaster Process.” It contains a Sentinel-2 Level-2A surface reflectance time series covering Bohetai Township, Zhaoyuan County, Daqing City, Heilongjiang Province, China, from January 19, 2018, to December 25, 2020. Images with scene-level cloud cover below 20% were selected and deduplicated by acquisition date, resulting in 108 observations.

Each image was clipped to the administrative boundary of Bohetai Township, resampled to a spatial resolution of 10 m, and projected to WGS 84/UTM Zone 51N (EPSG:32651). Each observation contains bands B02, B03, B04, B05, B06, B07, B8A, and B11, together with the Scene Classification Layer (SCL). The dataset can support crop growth curve construction, time-series anomaly detection, vegetation index calculation, crop lodging monitoring, and related agricultural remote-sensing research.
