Semi-Automated Classification of Landform Elements in Armenia Based on SRTM DEM using K-Means Unsupervised Classification

open access: yesQuaestiones Geographicae, 2017
Land elements have been used as basic landform descriptors in many science disciplines, including soil mapping, vegetation mapping, and landscape ecology. This paper presents a semi-automatic method based on k-means unsupervised classification to analyze

Study on Fractal Characteristics of Evolution of Mining-Induced Fissures in Karst Landform

open access: yesEnergies, 2022
The karst landscape is widespread in the southern region of China. As a result of underground mining activities, the original stress equilibrium is disrupted, causing the redistribution of stress in the overlying rock layer, inducing the longitudinal ...

Habitat and Landform Types Drive the Distribution of Carabid Beetles at High Altitudes

open access: yesDiversity, 2021
The high altitude mountain slopes of the Dolomites (Italian Alps) are characterized by great habitat and landform heterogeneities. In this paper, we investigated the effect of Nature 2000 habitat and landform types in driving the high altitude ground ...

Extracting Terrain Texture Features for Landform Classification Using Wavelet Decomposition

open access: yesISPRS Int. J. Geo Inf., 2021
Accurate landform classification is a crucial component of geomorphology. Although extensive classification efforts have been exerted based on the terrain factor, the scale analysis to describe the macro and micro landform features still needs standard ...

Consequence of interaction between soil erosion processes and dryland landforms [PDF]

open access: yesSustainable Earth Trends, 2021
Soil is directly linked to climate through the exchange of carbon between the atmosphere and the pedosphere. Anthropogenic-geomorphic disturbances and accelerated soil erosion processes stimulate spatial heterogeneity in the distribution of soil biotic ...
