ABSTRACT: Traditional method of soil survey is expensive, slow, and must be carried out by experienced researchers. Thus, advances in soil observation technologies and the need to obtain information quickly by modern techniques have intensified the use of proximal sensing. This study characterized surface reflectance spectra (A horizon) and related them to traditional soil classification, based on morphological, physical, and chemical properties of representative pedogenetic profiles, developed in two toposequences of the Distrito Federal, Brazil. In the toposequences, 15 soil […]

ABSTRACT Knowledge of soils is increasingly important for their correct use in agriculture, in urban growth, and in conservation of natural resources, among other purposes. However, there is a lack of qualified professionals for pedological characterization and mapping, particularly at scales of greater detail. Due to this shortage and due to advances in computational tools and remote sensing, Digital Soil Mapping (DSM) arose in order to assist and expedite pedological survey activities. Thus, the aim of this study was to […]
