REVISED PROGRESSIVE MORPHOLOGICAL METHOD FOR GROUND POINT CLASSIFICATION OF AIRBORNE LIDAR DATA

open access: yesInternational Journal of Built Environment and Sustainability, 2019
Airborne Light Detection and Ranging (LiDAR) has been very effectively used in collecting terrain information over different scales of area. Inevitably, filtering the non-ground returns is the major step of digital terrain model (DTM) generation and this

Extraction of thalweg networks from DTMs: application to badlands [PDF]

open access: yesHydrology and Earth System Sciences, 2010
To study gully spatial patterns in the badlands using a continuous thalweg vector network, this paper presents methods to extract the badlands' thalweg network from a regular grid digital terrain model (DTM) by combining terrain morphology indices with a

Forest Biomass Mapping Using Continuous InSAR and Discrete Waveform Lidar Measurements: A TanDEM-X/GEDI Test Study

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
This article addresses the implementation of an above ground biomass (AGB) estimation scheme relying on the height-to-biomass allometry at stand level in the context of the synergistic use of continuous TanDEM-X (bistatic) interferometric synthetic ...

Internal Permafrost Structure of Geomorphologically Distinct Palsas in Northern Sweden Revealed by Quasi‐3D ERT

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost in northern peatlands occurs within individual palsas or extensive peat plateaus and controls local carbon storage. These permafrost landforms are complex, and their internal structure remains poorly understood. We used quasi‐3D electrical resistivity tomography (ERT) measurements, supported by UAV‐LiDAR topography, frost probing ...

Integrating SfM, LiDAR and TLS for High‐Resolution Monitoring of Palsa Surface Changes and Degradation Dynamics

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Understanding fine‐scale surface changes is crucial for quantifying ecosystem dynamics and detecting landscape changes. Palsas, comparably small peatland elevations with an ice‐rich permafrost core, undergo natural cycles of growth and degradation. They can also serve as indicators of climate change in subarctic regions. Because they typically

Ditch network extraction and hydrogeomorphological characterization using LiDAR-derived DTM in wetlands

open access: yesHydrology Research, 2013
While much emphasis has been placed on the importance of hydrology as a driving force for wetlands, few small stream drainage networks have been mapped. Light Detection and Ranging (LiDAR) data can provide very high-precision topographic maps over large areas, and have been used to extract drainage networks in forested areas, vineyards, and high ...
