Predicting Runoff Risks by Digital Soil Mapping [PDF]

Revista Brasileira de Ciência do Solo, 2016
ABSTRACT Digital soil mapping (DSM) permits continuous mapping soil types and properties through raster formats considering variation within soil class, in contrast to the traditional mapping that only considers spatial variation of soils at the boundaries of delineated polygons. The objective of this study was to compare the performance of SoLIM (Soil

Using deep learning for Digital Soil Mapping [PDF]

SOIL, 2018
Abstract. Digital soil mapping has been widely used as a cost-effective method for generating soil maps. However, current DSM data representation rarely incorporates contextual information of the landscape. DSM models are usually calibrated using point observations intersected with spatially corresponding point covariates.

Compilation of novel and renewed, goal oriented digital soil maps using geostatistical and data mining tools

Hungarian Geographical Bulletin, 2015
Due to former soil surveys and mapping activities significant amount of soil information has accumulated in Hungary. Present soil data requirements are mainly fulfilled with these available datasets either by their direct usage or after certain specific ...

Mapping waterlogging of soils using digital terrain models [PDF]

Hydrological Processes, 1995
AbstractMaps of the potential waterlogging of soils were generated using hypotheses about the effect of topography on the soil water regime inspired by Beven and Kirkby's concept of saturation overland flow. The procedure was validated by comparing the simulated maps with maps derived from a 1: 25 000 soil survey for two contrasting catchments.

A review on digital mapping of soil carbon in cropland: progress, challenge, and prospect

Environmental Research Letters, 2022
Cropland soil carbon not only serves food security but also contributes to the stability of the terrestrial ecosystem carbon pool due to the strong interconnection with atmospheric carbon dioxide.
