New Satellite Mapping Reveals Vast Undetected Trees in Tropics, Highlighting Overlooked Losses

A recent study published in Nature Communications unveils that 17.31% of tropical tree cover—equivalent to 395.9 million hectares (Mha)—has been consistently overlooked by global forest monitoring systems. Using high-resolution satellite imagery (<5m) and an advanced automated algorithm, an international research team mapped previously undetected tree cover (PUTC) across pan-tropical regions from 2015–2022. Their findings highlight significant net losses and critical blind spots in current forest conservation efforts.

AI-Powered Radar Technique Reconstructs Cities in 3D with Greater Detail and Accuracy

A team of Chinese researchers has developed a powerful new method to create highly detailed 3D models of cities using radar data, helping overcome long-standing challenges in urban mapping. By combining artificial intelligence (AI) with building geometry, the new technique—called Geo-SETRA—can produce clearer, more complete images of urban landscapes, potentially transforming how cities are monitored, planned, and protected.

Haishao-1 Satellite Ushers in New Era of Low-Latitude Earth Observation

A new study published in The Innovation on May 12, 2025, highlights the launch of Haishao-1 (HS-1), China's first low-inclination orbit Synthetic Aperture Radar (SAR) satellite—marking a breakthrough in global Earth observation. Developed by the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences, in collaboration with the Innovation Academy for Microsatellites and AIRSAT Technology Group, HS-1 combines a lightweight design with high-performance imaging capacities. Uniquely positioned in a low-inclination orbit, the satellite is specifically designed to fill long-standing observational gaps in equatorial and tropical regions—areas that are frequently obscured by clouds and under-observed by conventional polar-orbiting satellites by delivering detailed, frequent radar imagery with remarkable clarity.
