The administrative map contains layers presenting all administrative levels shared by the Global Administrative Map. The data are freely available for academic use and other non-commercial use. Administrative layers are in shape file format, and it uses Geographic longitude-latitude projection (EPSG 4326).

Soil and climatic maps
Climatic data shared within this platform consists of dekadal (10 days) precipitation (mm) and potential evapotranspiration (mm). The Dekadal precipitation data is calculated from daily data (1998 -2013 for Vietnam and 2011-2020 for Bangladesh) downloaded from NASA Prediction of Worldwide Energy Resources. Potential evapotranspiration (PET) is computed from solar radiation (Mj/m2/day) and temperature (oC) following the Hargreaves' method. Map layers are resampled using the Thin Plate Spline method and stored in Geotiff format at a resolution of 5 arc minutes with Geographic longitude-latitude projection (EPSG 4326).

The data contains three layers for concentration (g/kg) of sand, silt, and clay particle sizes that make up soil texture or mineral fraction of the soil. The data is extracted from global soil texture layers at the depth of 0- 30cm with the Geographic longitude-latitude projection (EPSG 4326) shared by the Global gridded soil information. Soil texture layers have been resampled to a resolution of 5 arc minutes from the original resolution of 8 arc seconds.

The rice calendar and production layers of Bangladesh and Vietnam can be extracted from the Rice Atlas -- a spatial database consisting of data on rice planting and harvesting dates by growing season and estimates of monthly production for all rice-producing countries. The map layers are stored in shape file format and it uses Geographic longitude-latitude projection (EPSG 4326).
The rice calendar and production layers are available at IRRI Dataverse.
AWD Suitability maps
Samples of AWD suitability maps were developed for Bangladesh and Vietnam using the MapAWD tool, following the method introduced by Nelson et al. (2015) and Sander et al. (2017). The map is stored in Geotiff format, using Geographic longitude-latitude projection (EPSG 4326).
