Abstract

The AA. describe a new method to map intra-plot soil surface heterogeneities at a 5 cm spatial resolution. Their approach unites aerial image classification acquired at very high spatial resolution (VHSR) with local soil sampling. This method has been applied to a plot area located on the hillslopes of Burgundy vineyards (Monthelie, France), where decennial erosion data were already available, in order to assess the effect of soil surface characteristics and slope angle on erosion intensity and localisation. From this method, 4 classes of radiance were distinguished and interpreted as 4 soil surface state classes (SSC), defining specific areas within the studied plot. These SSCs have been characterised by their grain-size distribution, their organic carbon, calcium carbonate, and total nitrogen contents. This work shows that the spatial distribution of soil erosion is related to the local slope steepness but also to the spatial distribution of stoniness that results from water and tillage erosion processes
