Quantitative mapping of the soil rubification process on sand dunes, using field and airborne sensors Academic Article uri icon

abstract

  • Remote sensing of soils plays a major role in both soil survey and soil mapping applications. Traditional methods such as air photos and satellite images suffer from low spectral resolution and, thus, provide only limited spectral information about the targets explored. For soil survey applications, high-resolution imaging spectroscopy may be a key factor in implementing accumulated spectral-soil knowledge. Because the IS technology provides a near-laboratoryquality reflectance and emittance spectrum for each single picture element (pixel), it allows the identification of objects based on the spectral absorption features of the chromophores (Goetz et al. 1985, Clark and Roush 1984). In this regard it can be used to assess mineral changes on the soil surface and to better provide spatial view of pedogentic processes. One of the fundamental pedogenesis processes taking place along the …
