Ground‐based robotic remote sensing for standardized biodiversity monitoring in coastal habitats

Remote Sensing in Ecology and Conservation, EarlyView.
Illustrated workflow of the proposed citizen‐to‐robot monitoring pipeline: (i) expert‐validated citizen observations are translated into AI models, (ii) deployed on a ground‐based robotic platform for proximal sensing of coastal dune habitats, (iii) enabling standardized detection of ecological targets (e.g., Pancratium maritimum & Brithys crini), and (

Registration of Aerial Optical Images with LiDAR Data Using the Closest Point Principle and Collinearity Equations

Sensors, 2018
Registration of large-scale optical images with airborne LiDAR data is the basis of the integration of photogrammetry and LiDAR. However, geometric misalignments still exist between some aerial optical images and airborne LiDAR point clouds. To eliminate

Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

Remote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.

Airborne lidar observations of water vapour variability and transport [PDF]

, 2012
Water vapour, a minor constituent of the earth’s atmosphere, plays a major role in the radiation budget and the water cycle with important implications for weather and climate. Due to the heterogeneous distribution of its sources, evaporation, and sinks,

Coherent Doppler Lidar for Human Motion Detection Under Dense Foliage Obscuration [PDF]

EPJ Web of Conferences
Heavily foliated environments pose challenges for aerial surveillance systems because dense tree canopy obscures the view from airborne sensors. While direct detect foliage penetrating airborne lidar systems have proven effective at locating fixed ...

A review of the research and advancements in MSDF monitoring for the remote sensing of soil and water conservation in China

River, EarlyView.
Abstract With the advancement of remote sensing technology, the accuracy of satellite remote sensing data has continuously improved, and the precision of large‐scale soil and water conservation monitoring has steadily increased. However, owing to differences in sensor acquisition and processing methods, monitoring data obtained through various ...

Airborne Lidar Measurements.

The Review of Laser Engineering, 1995
Since the early 1980's, airborne lidar systems have been used for making remote measurementsof ozone, water vapor, and aerosols in studies of many important atmospheric processes. Recent ozone and aerosol investigations have been conducted in the troposphere over thetropical Atlantic and western Pacific and in the Arctic stratosphere, and water vapor ...

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric
