Descriptive analysis of spectral curves by attributes

The user will be able to learn how to observe soil spectra patterns (characteristic of the spectral curve of the soil sample(s)), according to its physical, chemical and mineralogical characteristics through BraSpecS system filter commands. For example, if the user wishes to know what the spectral pattern of a sandy soil is like. Just select in the "Texture" filter the option "Arenosa" and the image of the average spectral curve of all BSSL spectral data of samples of sandy soils will be generated. The user can either familiarize themselves with the pattern of it, or can compare his own spectral curve (acquired with his own equipment) with the figure presented on the site. The filtering can still be more or less selective since the following filters are available: State, WRB classification, SiBCS classification in different hierarchical levels, sample collection layer, that is, whether surface or subsurface data is desired.
