Multi-model Approach for Tree Detection and Classification in Wallonia Region (Belgium) Open
Forests play a pivotal role in global ecosystems by sequestering carbon, preserving biodiversity, and providing valuable resources for both humans and wildlife. Monitoring and management of these forests require accurate, up-to-date inform…

Window-Based Morphometric Indices as Predictive Variables for Landslide Susceptibility Models Open
The identification of areas that are prone to landslides is essential in mitigating associated risks. This is usually achieved using landslide susceptibility models, which estimate landslide likelihood given local terrain conditions and th…

How robust are landslide susceptibility estimates? Open
Much of contemporary landslide research is concerned with predicting and mapping susceptibility to slope failure. Many studies rely on generalised linear models with environmental predictors that are trained with data collected from within…

Geomorphic analysis of transient landscapes in the Sierra Madre de Chiapas and Maya Mountains (northern Central America): implications for the North American–Caribbean–Cocos plate boundary Open
We use a geomorphic approach in order to unravel the recent evolution of the diffuse triple junction between the North American, Caribbean, and Cocos plates in northern Central America. We intend to characterize and understand the complex …
