Digital image analysis of outcropping sediments: Comparison to photospectrometric data from Quaternary loess deposits at Şanoviţa (Romania) and Achenheim (France) doi
The possibility to use colour data, as extracted from two selected loess-paleosol sequences, is discussed here. Colour data are a fast and inexpensive method of proxy data generation. We compare the outcome from analysing outcrop images taken by digital cameras in the field and spectral colour data as determined under controlled laboratory conditions. By nature, differences can be expected due to variations in illumination, moisture, and sample preparation. Outcrop inclination may be an issue for...
