Global Computable Seamless Data Cube


Global 30-m Seamless Data Cube of Land Surface Reflectance

The ​​Global 30-m Seamless Data Cube (SDC)​​ (2000–2022) integrates Landsat 5/7/8/9 and MODIS Terra data to produce a gap-free surface reflectance product. Unlike other Landsat-based datasets, it offers ​​improved land change detection​​ and ​​spatiotemporal consistency​​, making it ideal for large-scale land cover and land use change studies.
