Classification Methodology

The map was generated using the classifier "SACLASS2" developed by JAXA, integrating multi-temporal Sentinel-2/MSI optical data and ALOS-2/PALSAR-2 SAR data. This approach captures the distinct phenological characteristics of South Asian agricultural cycles.

Accuracy Assessment

The national-scale map achieved robust overall accuracy across both periods, validating the reliability of multi-temporal satellite data integration.
