The defended thesis presents innovative research on the vertical accuracy of global digital elevation models (DEMs) with emphasis on the TanDEM-X DEM as the latest addition to the global DEMs. It is based on three scientific papers: Study 1  – TanDEM-X DEM Accuracy: Published in Remote Sensing of Environment—the leading journal in the field—this study…

Choosing the Optimal Global Digital Elevation Model forStream Network Delineation: Beyond Vertical Accuracy The Importance of Digital Elevation Models (DEMs)Global digital elevation models (DEMs) are vital for various hydrological applications, including stream network delineation and flood modeling. However, their accuracy often suffers from vegetation and building offsets, making bare-earth DEMs a promising alternative. This study…

We are delighted to announce that a member of our team, Jan Komárek, has been selected as an evaluator of project proposals within the prestigious Biodiversa+ program. This program focuses on biodiversity research, and its 4th call, titled „Biodiversity and Transformative Change“ (BiodivTransform), represents an ambitious initiative supporting innovative projects aimed at nature conservation and…

A new article by Elisa Marchetto and her team addresses the growing issue of biases and uncertainties in large-scale biodiversity databases, which are essential for biodiversity research and conservation on a continental scale. Expansion of Biodiversity Databases and Their Limitations The growth of biodiversity databases, such as BIEN and sPlot, presents crucial opportunities for research…

Mapping Indicator Species of Segetal Flora for Result-Based Payments in Arable Land Using UAV Imagery and Deep Learning A recent study published in Ecological Indicators (December 2024) explores an innovative approach to monitoring indicator species of segetal flora in arable fields using UAV imagery and deep learning. The research, conducted by Caterina Barrasso and colleagues,…

Research Article by Vítězslav Moudrý. Introduction to GEDI Data Filtering The Global Ecosystem Dynamics Investigation (GEDI) mission collects terrain and canopy height data using spaceborne lidar. While it provides invaluable forest and grassland height metrics, accurately using GEDI data requires filtering out noisy and low-quality observations affected by environmental and acquisition conditions. This study aims…

In a newly published study, researchers led by Vítězslav Moudrý have conducted a detailed analysis of three global canopy height maps: the Global Forest Canopy Height (GFCH), the High-Resolution Canopy Height Model of the Earth (HRCH), and the Global Map of Tree Canopy Height (GMTCH). The study, titled „Comparison of three global canopy height maps…

We are thrilled to congratulate Michela Perrone, who has successfully completed her PhD at the Department of Spatial Sciences. Her remarkable journey was supported by her supervisors, Marco Malavasi and Vítězslav Moudrý, who guided her every step of the way. The EarthBridge project also played a key role, with Prof. Anna Cord from the University…
