TESSERA: Temporal Embeddings of Surface Spectra for Earth Representation and Analysis Open
Satellite Earth-observation (EO) time series in the optical and microwave ranges of the electromagnetic spectrum are often irregular due to orbital patterns and cloud obstruction. Compositing addresses these issues but loses information wi…

SPREAD: A large-scale, high-fidelity synthetic dataset for multiple forest vision tasks Open
We present the Synthetic Photo-realistic Arboreal Dataset (SPREAD), a state-of-the-art synthetic dataset specifically designed for forest-related machine learning tasks. Developed using Unreal Engine 5, SPREAD goes beyond existing syntheti…

An app for tree trunk diameter estimation from coarse optical depth maps Open
Trunk diameter is related to the overall health and level of carbon sequestration in a tree. Trunk diameter measurement, therefore, is a key task in both forest plot and urban settings. Unlike the traditional approach of manual measurement…
