Time: 6:00 AM - 7:35 AM
Moderator: N/A
Mapping African soils at 30m resolution - iSDAsoil - Eastern Time Zones

“iSDAsoil” combines remote sensing data and other geospatial information with carefully stratified point samples subjected to spectral analysis and traditional wet chemistry reference analysis. State of the art machine learning techniques were used to create digital maps of 17 agronomically important soil properties at 3 depths, including estimates of uncertainty.

iSDAsoil is designed to encourage sharing and we hope that the owners of other soil and agronomic data, in industry and academia, will share their datasets to help create ever more accurate maps. If you would like to access the resource ahead of the session, please visit the iSDAsoil website:

This interactive session will include a detailed demonstration of the resource, panel member feedback on use and prospects of iSDAsoil, answering FAQ received ahead of the session, and an open discussion with session participants on user experience and further developments.

I am a trained farmer and holding a PhD in agronomy. The last 20 years I am working with spectroscopic applications in the agricultural space. Since more than a decade I have changed the focus on bringing research to business and creating impact for farmers. Currently my team and I are paving the way for making analytical and advisory services for the big mass of African farmers available and affordable.
