Author: Kateřina Gdulová Global radar-based Digital Elevation Models (DEMs), such as TanDEM-X and SRTM, are widely used to represent different aspects of the Earth’s surface. However, one key question often goes unaddressed: Are these DEMs digital terrain models (DTMs) or digital surface models (DSMs)? These models are used as both DTMs and DSMs, sometimes without…

Author: Tomáš Klouček Darkness, once an integral part of life on Earth, is now rapidly vanishing. The spread of artificial lighting—often excessive, misdirected, or poorly regulated—has created a form of pollution that is both overlooked and far-reaching. Known as light pollution, it disrupts ecosystems, affects human health, and fundamentally alters our relationship with the night…

Author: Michal Kučera To make the most of my PhD journey, I sought early experience through a short research exchange at the University of Bonn. I wanted to immerse myself in a concentrated research environment, which I believed would help me refine my research concept and uncover connections with other scholars’ work. By engaging with…

Author: Dominika Prajzlerová Species Distribution Models (SDMs) are powerful tools that help scientists understand where species live—and why—by linking species occurrences to environmental conditions. These models often use remote sensing (RS) data from satellites to describe habitat conditions across large areas. But one key question often goes overlooked: When is the best time to acquire…

Author: Giorgi Kozhoridze A joint research initiative between the Czech University of Life Sciences in Prague and Tel Aviv University aimed to explore a frequently neglected impact of invasive plant species: their capacity to alter the local climate. Concentrating on the delicate coastal sand dunes of the eastern Mediterranean, the research investigated how two invasive…

Author: Juan Alberto Molina Valero These days, with drones and satellites capturing stunning views from above, it’s easy to forget that some of the most powerful tools for understanding our forests are still on the ground. In our recent study, we explored how a ground-based laser scanning tool—called terrestrial laser scanner (TLS)—can help us measure…

Author: Vitezslav Moudry Recent months have been marked by the completion and evaluation of student theses. It should come as no surprise that the students I have supervised have often worked with laser altimetry data in some way and that these theses are closely related to what we are doing in EarthBridge. Two studies validated…

Author: Jan Komárek Drones have revolutionised environmental monitoring, promising on-demand, high-resolution data collection in places satellites can’t reach. But beneath the hype lies a harsher reality: weather. I analysed meteorological records from 31 Czech locations (2016–2024) and found that drones are actually grounded about 75 % of the time. Here’s why—and what we can do…

Author: Jan Komárek From March 2nd to 8th, 2025, we had the opportunity to participate in the 2nd Polar Winter School in Hvanneyri, Iceland, organized by the Czech University of Life Sciences Prague in collaboration with Landbúnaðarháskóli Íslands and the Nordic Snow Network. The event brought together students and experts from 14 countries, focusing on…
