Spectral diversity beyond the Spectral Variation Hypothesis: what comes next?
Author: Michela Perrone Nearly three decades ago, the Spectral Variation Hypothesis (SVH) proposed a tremendously simple idea: the spectral diversity of vegetated landscapes (essentially, the spatial variation in reflectance detected by remote sensing) could serve as a proxy for plant species richness. The promise of biodiversity mapping from space quickly gained traction, especially with multispectral…

We are building corner reflectors!
How Can a Satellite Detect Movement on Earth? Author: David Moravec Electromagnetic radiation behaves like a wave. When a satellite equipped with a microwave antenna sends a radar signal toward Earth, it receives a reflected wave in return. But here’s the trick—waves have phases (they oscillate up and down like ocean waves). By measuring the…

Vítězslav Moudrý in Dresden
I visited TU Dresden twice in the last two weeks. During the first visit, I worked intensively with Xiao Liu on the revision of our paper, which focuses on using GEDI to assess changes in forest vertical structure over time. The opportunity to work and discuss the text together in person was very refreshing compared…

Successful PhD Defense of Kateřina Gdulová! 🎓
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…

Members of the EarthBridge team collaborated on a new article.
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…

Addressing multiple facets of bias and uncertainty in continental scale biodiversity databases
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…
