New deFOREST Pipeline Fuses Satellite Data for Advanced Deforestation Detection

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new deforestation detection pipeline called deFOREST that fuses optical and radar satellite data for enhanced sensing. The system constructs anomaly maps from optical data using a discrete Karhunen-Loéve expansion, quantifying anomalies without requiring prior knowledge of data distribution. These optical anomaly maps are then combined with radar data and classified using a Hidden Markov Model. Tested in the Amazon forest with Sentinel-1 and Sentinel-2 data, the deFOREST approach demonstrated superior accuracy compared to existing hybrid methods, particularly in regions with sparse optical data due to cloud cover.

    deFOREST: Fusing Optical and Radar satellite data for Enhanced Sensing of Tree-loss

    arXiv:2510.14092v2 Announce Type: replace-cross Abstract: In this paper we develop a deforestation detection pipeline that incorporates optical and Synthetic Aperture Radar (SAR) data. A crucial component of the pipeline is the construction of anomaly maps of the optical data, wh…
