2.3.2. Slope Rasters

Various derivatives of raster data show a positive impact on classification results. According to Haburaj et al. [12], the spectral slope between red, green, and blue channels—while introducing more noise—can help to identify organic material in the images. Slope rasters were therefore created for both the RGB and the multispectral image data, leading to two and five additional raster layers, respectively.
