Estimation of Parameters in Inhomogeneous Neyman‐Scott Processes Using Presence/Absence Data

Environmetrics, Volume 37, Issue 2, March 2026.
ABSTRACT Environmental monitoring is of particular importance for studying biodiversity and ecosystems. Many environmental monitoring programs emphasize plant registrations as part of their inventory responsibilities. Among the various methods available for surveying plant communities, we focus on presence/absence (P/A) sampling due to its ...

High‐resolution LiDAR and stereo‐DEMs for debris flow analysis in the Western Ghats, India: Sediment volume computation and run‐out modeling

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
The 2020 Pettimudi debris flow in the Western Ghats of India killed 70 people. Our study using stereo‐DEM, UAV‐based LiDAR data, and field data estimated the sediment loss as 17 × 104 m3. Abstract Computation of sediment volume and accurate modeling of run‐out using high‐resolution digital elevation models (DEMs) are essential for assessing debris flow

Long‐Range Time‐Correlated Single‐Photon Counting Lidar 3D‐Reconstruction From a Moving Ground Vehicle

Journal of Field Robotics, Volume 43, Issue 2, Page 1178-1192, March 2026.
ABSTRACT Time‐correlated single‐photon counting (TCSPC) lidar enables high‐resolution 3D imaging at kilometer range. While previous works have covered long range TCSPC 3D imaging from either stationary or airborne platforms, this is, to the best of our knowledge, the first attempt that use a moving ground vehicle. Fusing measurements taken at different

Pollution to Solution: Understanding and Addressing Microplastic Contamination in the Environment

Environmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT In general, plastic pollution results from the unintentional release of macroplastic materials into the environment as well as the deliberate production and usage of small plastic particles (micro‐ and nano‐sized plastic particles) in a variety of consumer products micro and nanoplastics in filtrate freshwater and marine environments because ...

Automatic glacier surface analysis from airborne laser scanning

, 2007
Glaciers are interesting phenomena to scientists, mountaineers and tourists. Glaciers have a great impact on the local economy, power generation and water supply. Furthermore, the behaviour of glaciers is influenced by climate variations, such as changes in temperature. Monitoring glaciers can therefore give valuable insight to glaciologists.

Spatial Variability of Sea State in the German Bight and Influence of Offshore Wind Farms

Wind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT Offshore wind farms are growing worldwide and increase the source of renewable energy. However, as the extent and density of offshore wind farms increase, there is growing importance to understand the interactions with physical systems and the marine environment, in particular, the sea state.

ALB Evaluation for NOAA charting requirements [PDF]

, 2013
The National Oceanic and Atmospheric Administration (NOAA) acquires hydrographic data around the coasts of the US and its territories using in-house surveys and contracting resources. Hydrographic data are primarily collected using sonar systems, while a

Beyond discrete visibility estimates: single‐scan LiDAR provides an efficient method for 3D viewshed estimation

Wildlife Society Bulletin, Volume 50, Issue 1, March 2026.
We demonstrated a new approach for estimating fine‐scale 3‐dimensional (3D) visibility based on single scans from a terrestrial laser scanner. Our method produced results that were comparable to traditional 2D visibility estimates assessed with profile boards but provides comprehensive information across all directions and continuous distances ...

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...
