Description

USDA Texture Class at soil depths of 0-20 cm and 20-50 cm.

In areas of dense jungle (generally over central Africa), model accuracy is low and therefore artefacts such as banding (striping) might be seen. Soil property predictions were made by Innovative Solutions for Decision Agriculture Ltd. (iSDA) at 30 m pixel size using machine learning coupled with remote sensing data and a training set of over 100,000 analyzed soil samples. Further information can be found in the FAQ and technical information documentation. To submit an issue or request support, please visit the iSDAsoil site.
