A procedure for delineating a search region in the UAV-based SAR activities
We propose a simple geometrical approach for delineating a region above which an Unmanned Aerial Vehicle (UAV) should fly to support the Search and Rescue (SAR) activities.

Surface network extraction from high resolution digital terrain models
A surface network is a topological data structure formed by a set of thalwegs and ridges on a digital terrain model. Its computation relies on the detection of saddles on the terrain.

Asymmetric Changes in the Cooling Capacity of China's Lakes
Abstract Lakes significantly influence local climate, yet a systematic assessment of their cooling effect across diverse regions remains limited. This study develops a multi‐metric (spatial extent, magnitude, and efficiency) framework to evaluate the spatiotemporal patterns of Lake Cooling Capacity (LCC) for 265 major Chinese lakes from 1980 to 2022 ...

The true 3-D surface reconstruction using a multi-UAV cooperation method
Geomorphometry research largely relies on 3-dimentional land surface models, especially for natural landforms with steep slopes and large complex artificial structures. The traditional Digital Elevation Model (DEM) encounters difficulties in representing

ABSTRACT Climate change is intensifying the frequency and impact of extreme weather events, particularly in vulnerable Mediterranean environments. This study investigates relative morphometric changes within a gully system in the Guadalmedina River basin (Málaga, southern Spain) triggered by the 2024 DANA (Depresión Aislada en Niveles Altos), a high ...
