 This article describes an environmental remote sensing application using a UAV to reduce data gaps between field and satellite scale in soil erosion monitoring in Morocco, utilizing a serious iFixed Wing aircraft equipped with a digital system camera and employing two different geofereasing approaches for creating high-resolution DTM and ortho-image mosaics. The resulting data products were used to quantify gully and bad land erosion and analyze landscape development for larger extents. This article was authored by Johannes B.
