Possible contribution of remote sensing to soil monitoring

A slideshow for a lecture given for the online training activity “Supporting Capacity Building in Soil Monitoring in Europe” organised for Task T5.4 of PREPSOIL project (CSA, Horizon EUrope).

It is based on the results of Task 5.2 and shows that:

• Although necessary, soil monitoring methods based on in situ observations or soil sampling are costly, give estimates with low spatial & temporal resolutions, and provide no information on uncertainties outside the characterized sites; 
• RS provides access to certain soil information or makes soil property covariates available with a spatial resolution and revisit frequency that can be very high;
• By using both soil data and other data including RS data, digital soil mapping makes it possible to obtain precise property maps, as well as uncertainty maps.
