Historic cartography of L'Aquila city as a support to the study of earthquake damaged buildings [PDF]

, 2013
The city-center of L'Aquila suffered big damages from the main seismic event (6th April 2009, 3:32 a.m., local time; Ml=5.8, Mw= 6.2) of the seismic sequence that included hundreds of aftershocks (more than 30 of them 3.5<5.0) (INGV, 2009). Causes and

Meander‐Bend Erosion Dynamics Along a Gravel‐Bed River: Insights From Short‐Term UAV Monitoring

River Research and Applications, EarlyView.
ABSTRACT Riverbank erosion is a natural process in meandering rivers that contributes to sediment supply and geomorphic diversity, yet it can threaten infrastructure and human activities within the floodplain. Recently, many studies have used high‐resolution remote sensing technologies to measure bank erosion, but they often focus on technical aspects ...

High resolution satellite imagery orientation accuracy assessment by leave-one-out method: accuracy index selection and accuracy uncertainty [PDF]

, 2008
The Leave-one-out cross-validation (LOOCV) was recently applied to the evaluation of High Resolution Satellite Imagery orientation accuracy and it has proven to be an effective method alternative with respect to the most common Hold-out-validation (HOV),

Using time‐series remote sensing to identify and track individual bird nests at large scales

Remote Sensing in Ecology and Conservation, EarlyView.
Time‐series airborne imagery can potentially track individuals over time to collect information beyond one‐off counts. Using weekly UAS‐based imagery of wading bird colonies, we develop an automated approach to identifying nests. Our algorithmic approach detected 68–74% of known nests and exhibited similar performance to human review of imagery ...

Deep learning‐based super‐resolution reconstruction and improved YOLOv9 for efficient benthos detection: a case study at Lake Hamana, Japan

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

Practical Methodology for Developing Visions for Carbon‐Neutral Cities and Communities

Sustainable Development, EarlyView.
ABSTRACT Cities and communities play important roles in sustainable development and climate change mitigation. This study presents a novel framework for developing carbon‐neutral visions for cities and communities. We established five “principles,” investigated options encompassing four parameters (management, goal setting, actions, and quantification),

Sargassum Lung Syndrome: Air Flow Obstruction and Bronchial Inflammation Are Observed After Prolonged Exposure to Sargassum Gas Emissions in the Eastern Caribbean

Environmental Toxicology, EarlyView.
ABSTRACT Sargassum inundation of Caribbean and American shorelines is a growing environmental hazard. Hydrogen sulfide (H2S) and ammonia (NH3) produced by decomposing Sargassum could be involved in airway obstruction and bronchial inflammation. The study was undertaken to evaluate the effects of exposure to H2S and NH3 gases emitted during Sargassum ...

Why you need to use ground control points (GCP) for drone mapping

GEOmedia
The article explains why Ground Control Points (GCPs) remain essential in drone mapping, even with the advent of RTK/PPK drones. GCPs act as reliable reference markers that correct positional errors, ensuring that aerial imagery aligns accurately with ...
