Paleoseismic Evidence of Recent Co‐Seismic Ruptures in Western Tierra del Fuego, Chile

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The Magallanes‐Fagnano fault (MFF) in Tierra del Fuego (TDF) is a major left‐lateral transform boundary between the South American and Scotia plates. While surface ruptures associated with the 1949 earthquakes have been documented in Argentina east of the Fagnano Lake, their extension to the west remained uncertain.

FILTERING PHOTOGRAMMETRIC POINT CLOUDS USING STANDARD LIDAR FILTERS TOWARDS DTM GENERATION

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Abstract. Digital Terrain Models (DTMs) can be generated from point clouds acquired by laser scanning or photogrammetric dense matching. During the last two decades, much effort has been paid to developing robust filtering algorithms for the airborne laser scanning (ALS) data.

Least Squares Compactly Supported Radial Basis Function for Digital Terrain Model Interpolation from Airborne Lidar Point Clouds

Remote Sensing, 2018
To overcome the huge volume problem of light detection and ranging (LiDAR) data for the derivation of digital terrain models (DTMs), a least squares compactly supported radial basis function (CSRBF) interpolation method is proposed in this paper.

Migrating and Nonmigrating Neutral Mass Density Tides From GRACE‐FO Observations for Solar Minimum Conditions

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This study presents the migrating and nonmigrating thermospheric neutral mass density tides from the Gravity Recovery And Climate Experiment Follow‐On (GRACE‐FO) observations under solar minimum conditions (year 2020). The observed densities are first mapped to a reference altitude of 500 km using an empirical model (NRLMSIS 2.0) to remove the

Up-to-date high-resolution understory terrain extraction based on satellite stereo photogrammetry and spaceborne LiDAR

Forest Ecosystems
Accurate digital terrain models (DTMs) are essential for a wide range of geospatial and environmental applications, yet their derivation in forested regions remains a significant challenge.

Structure‐Aware Unsupervised Transmission Corridor Structure Extraction From 3DEP Lidar Using Graph Attention Embeddings and Reinforcement‐Learned DBSCAN

Transactions in GIS, Volume 30, Issue 5, August 2026.
ABSTRACT Transmission corridors are critical components of power delivery infrastructure, and their large‐area monitoring increasingly relies on national‐scale airborne lidar programs. This study presents an unsupervised, scalable framework for extracting transmission corridor structures (including conductors and supporting towers) from U.S. Geological

Algorithm for Extracting Digital Terrain Models under Forest Canopy from Airborne LiDAR Data

Remote Sensing, 2014
Extracting digital elevationmodels (DTMs) from LiDAR data under forest canopy is a challenging task. This is because the forest canopy tends to block a portion of the LiDAR pulses from reaching the ground, hence introducing gaps in the data.

Beyond the panacea narrative: Evaluating the capabilities and limitations of remote sensing for biodiversity net gain in England

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Five priorities for integrating remote sensing into biodiversity net gain in England, highlighting the need for transparent, validated, and interpretable approaches that complement, rather than replace, ecological field surveys. Abstract In England, biodiversity net gain (BNG) is a relatively new mandatory approach applied to many development sites ...

Characterisation of the surface morphology of an alpine alluvial fan using airborne LiDAR [PDF]

Natural Hazards and Earth System Sciences, 2008
Alluvial fans of alpine torrents are both natural deposition areas for sediment discharged by floods and debris flows, and preferred sites for agriculture and settlements.
