A novel approach for the representation of multispectral samples in a planar pentagon plot
Original language description
Graphic representation of multispectral samples in remote sensing is usually limited to single-band histograms or red-infrared scattergrams reflecting the importance of these two spectral bands for vegetation studies. Here a novel straightforward method of graphic representation of five bands in two-dimensional space, a pentagon plot is proposed, in which spectral bands are assigned to vertexes of the pentagon. Each multispectral sample is represented by a set of vectors pointing towards the respective vertices with their starting point in the centre of the pentagon. The magnitude of the vectors is given by reflectance values. The position of the sample in the plot is determined by vector addition. This is followed by scaling in the radial direction to achieve a better distribution of points in the plot area. The potential of a pentagon plot to analyse the content of a multispectral dataset is explored with examples of different sites using Sentinel-2 data. Different surface classes appear as distinct patches in the plot while gradients such as an increase in the amount of vegetation or suspended particles in water bodies are represented by localized curves in the plot. Furthermore, the use of the pentagon plot for quick characterisation of a satellite image, based on randomly selected points, is proposed.
