Mapping agricultural drought in the Dong Nai river basin with Google Earth Engine
By integrating Landsat 8 satellite imagery with the NDVI, LST, and VTCI indices on the Google Earth Engine platform, researchers from the Southern Institute of Water Resources Planning have developed an agricultural drought-zoning map for the Dong Nai River Basin for 2014–2024. Comparisons with reference drought indices and field survey findings suggest that the approach has potential for identifying drought-prone areas, particularly agricultural areas outside the service areas of irrigation infrastructure.
