On the uncertainty of stream networks derived from elevation data: the error propagation approach [PDF]

, 2010
DEM error propagation methodology is extended to the derivation of vector-based objects (stream networks) using geostatistical simulations. First, point sampled elevations are used to fit a variogram model.

The true 3-D surface reconstruction using a multi-UAV cooperation method

, 2023
Geomorphometry research largely relies on 3-dimentional land surface models, especially for natural landforms with steep slopes and large complex artificial structures. The traditional Digital Elevation Model (DEM) encounters difficulties in representing

Assessing multifunctional mountain landscape in an Eastern European framework

Geographical Research, Volume 64, Issue 2, May 2026.
The research introduces the Biocultural Resilience Index (BRI), a novel tool for assessing multifunctional landscape sustainability. By integrating biological, cultural, and socio‐economic indicators, the BRI identifies vulnerable areas and informs strategies for sustainable management.

Automated Feature Extraction and Classification of Submerged Cultural Heritage Assets in the Puck Lagoon via Multisensor Remote Sensing

Archaeological Prospection, Volume 33, Issue 2, Page 397-421, April/June 2026.
ABSTRACT This study presents a strong framework for the detection and classification of Submerged Cultural Heritage Assets (SCHA) in shallow marine environments using the integration of multibeam echosounder and airborne LiDAR bathymetry with object‐based image analysis and fuzzy logic–based classification.

The scale free and scale - bound properties of land surfaces: fractal analysis and specific geomorphometry from digital terrain models [PDF]

, 1990
The scale-bound view of landsurfaces, being an assemblage of certain landforms, occurring within limited scale ranges, has been challenged by the scale-free characteristics of fractal geometry.

Surface network extraction from high resolution digital terrain models

Journal of Spatial Information Science, 2021
A surface network is a topological data structure formed by a set of thalwegs and ridges on a digital terrain model. Its computation relies on the detection of saddles on the terrain.

Asymmetric Changes in the Cooling Capacity of China's Lakes

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Lakes significantly influence local climate, yet a systematic assessment of their cooling effect across diverse regions remains limited. This study develops a multi‐metric (spatial extent, magnitude, and efficiency) framework to evaluate the spatiotemporal patterns of Lake Cooling Capacity (LCC) for 265 major Chinese lakes from 1980 to 2022 ...

Cryoconite holes geomorphometry, spatial distribution and radiative impact over the Hells Gate Ice Shelf, East Antarctica

Annals of Glaciology
Cryoconite holes are structures characteristic of the glacierised ablation areas, formed from dark sediment deposition which melt the glacier ice leading to their cylindrical structure formation. The present study focuses on an unstudied blue ice area of

Assessing Relative Gully Morphometric Change After Extreme Rainfall Events: A UAV‐Based GIS Framework Applied to the 2024 DANA in Southern Spain

Transactions in GIS, Volume 30, Issue 1, February 2026.
ABSTRACT Climate change is intensifying the frequency and impact of extreme weather events, particularly in vulnerable Mediterranean environments. This study investigates relative morphometric changes within a gully system in the Guadalmedina River basin (Málaga, southern Spain) triggered by the 2024 DANA (Depresión Aislada en Niveles Altos), a high ...

High‐Resolution Ensemble Modelling of Coral Distributions in the Northern Gulf of Mexico Based on Geomorphometry: Coral Diversity and Benthic Habitat Fragmentation From Oil and Gas Infrastructure to Inform Spatial Planning

Aquatic conservation
The northern Gulf of Mexico is home to several species of corals that provide a wide range of ecosystem services to other organisms. Oil and gas infrastructure, such as platforms and pipelines, form an extensive network throughout the northern Gulf of ...
