Soil-terrain modelling and erosion analysis at field scale level, a case study

open access: yesSoil and Water Research, 2009
Pedometrical methods and digital soil mapping represent a progressive approach to the evaluation of various terrain-related soil processes. A detailed digital terrain model was used for the analysis of erosion - sedimentation situation and description of

Probability maps as a measure of reliability for indivisibility analysis [PDF]

open access: yesSpatium, 2005
Digital terrain models (DTMs) represent segments of spatial data bases related to presentation of terrain features and landforms. Square grid elevation models (DEMs) have emerged as the most widely used structure during the past decade because of their ...
