Expansion of the Sahara Desert and shrinking of frozen land of the Arctic. [PDF]

open access: yes, 2020
Expansion of the Sahara Desert (SD) and greening of the Arctic tundra-glacier region (ArcTG) have been hot subjects under extensive investigations. However, quantitative and comprehensive assessments of the landform changes in these regions are lacking ...

Regional‐Scale Landscape Response to an Extreme Precipitation Event From Repeat Lidar and Object‐Based Image Analysis

open access: yesEarth and Space Science, Volume 9, Issue 12, December 2022., 2022
Abstract Extreme precipitation events may cause flooding, slope failure, erosion, deposition, and damage to infrastructure over a regional scale, but the impacts of these events are often difficult to fully characterize. Regional‐scale landscape change occurred during an extreme rain event in June 2012 in northeastern Minnesota.

A Deeper Look Into the 2021 Tyrnavos Earthquake Sequence (TES) Reveals Coseismic Breaching of an Unrecognized Large‐Scale Fault Relay Zone in Continental Greece

open access: yesTectonics, Volume 41, Issue 12, December 2022., 2022
Abstract Large magnitude (Mw ∼ ≥6) earthquakes in extensional settings are often associated with simultaneous rupture of multiple normal faults as a result of static and/or dynamic stress transfer. Here, we report details of the coseismic breaching of a previously unrecognized large‐scale fault relay zone in central Greece, through three successive ...

Integrating plot‐based and remotely sensed data to map vegetation types in a New Zealand warm‐temperate rainforest

open access: yesApplied Vegetation Science, Volume 25, Issue 4, October/December 2022., 2022
We demonstrated a new workflow to extend and map a national classification into a new area. Three associations could be mapped using remotely sensed predictors alone (Sentinel and LiDAR), whereas two also required environmental predictors. Our map will guide the indigenous peoples of the area to manage threats to valued communities and their species ...

An Ontology for Submarine Feature Representation on Charts [PDF]

open access: yes, 2013
A landform is a subjective individuation of a part of a terrain. Landform recognition is a difficult task because its definition usually relies on a qualitative and fuzzy description.

Granite Landscapes, Geodiversity and Geoheritage—Global Context

open access: yesHeritage, 2021
Granite geomorphological sceneries are important components of global geoheritage, but international awareness of their significance seems insufficient. Based on existing literature, ten distinctive types of relief are identified, along with several sub ...

Landform Classification in Raster Geo-images [PDF]

open access: yes, 2004
We present an approach to perform a landform classification of raster geo-images to obtain the semantics of DEMs. We consider the following raster layers: slope, profile curvature and plan curvature, which have been built to identify the intrinsic properties of the landscape. We use a multi-valued raster to integrate these layers. The attributes of the
