A Moral Case for a Humanitarian Satellite: At what point does inaction become unconscionable? What does it say about our world when we spend over $54 billion a year on defense and intelligence satellites to spy on each other - yet cannot dedicate even one satellite to saving lives? We take pic...

It's about time that the space race included missions that actually help the people.

Big Bird: A global dataset of birds in drone imagery annotated to species level Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 diffe...

In this work led by Josh Wilson, we labelled 4824 drone-based images containing 49990 birds from 101 species and trained a bird detection and ID model. The model achieved precision = 0.91 for detection & 0.65 for species/age/sex classification.

How can a β€œDigital Twin” help to build a more resilient agricultural future?

The #EOAgriTwin project creates virtual replicas of agricultural systems to monitor crop conditions under various stressors.

In two weeks, world leaders and tech executives will descend on Delhi for the AI Impact Summit 2026. There, power brokers will paint a pretty picture of the role AI will play in saving the world - from sharing prosperity to fixing climate change.

🌍 Geospatial data science in 2025 still comes down to two words: foundation models. And over the past months, we’ve had the chance to put that idea into practice for global flood mapping.

Photograph taken from the International Space Station by astronaut Nichole Ayers, capturing a rare gigantic jet β€” an upward lightning discharge shooting from a thunderstorm about 90-100 km high into the upper atmosphere. The jet appears as a vivid purple and blue column of light that finely branches out toward the top where it turns into a vivid red color. It's rising from a brightly illuminated cloud top, surrounded by diffuse city lights from Northern Mexico and South Texas. Behind it is the curved limb of Earth with a green band from the airglow layer indicating the edge of the atmosphere. A portion of the space station’s robotic arm is visible in the foreground.

On July 3rd, astronaut Nichole Ayers photographed a rare Gigantic jet from the ISS. These upward directed electrical discharges extend 90-100 km high into the atmosphere.

Our team had the opportunity to access SPOT6/7 data (1.5 m resolution) for Mozambique! We produced ~21 million individual field delineations for 2023, which allow unique insights into the spatial distribution of agriculture, field size and the linkages between agriculture and forest cover change!

The reason behind it is oftentimes constrained access to satellite imagery at very high spatial resolution needed in these systems (also see bsky.app/profile/phil...).

The literature on field delineation in smallholder systems remains relatively scarce and progress is slow overall (although cudos to the colleagues working on it). Therefore we donΒ΄t have field delineations at policy-relevant scales (e.g. national) where they are most needed.

Smallholder-dominated landscapes are entirely different from the mechanized and consolidated landscapes (which are oftentimes considered for benchmarking AI models).

Despite free access to petabytes of satellite data, cloud computing platforms, and a wealth of high-performing computer vision models, satellite-based field delineation simply doesnΒ΄t work in landscapes dominated by smallholders (fragmented, heterogeneous, and dynamic)!

We have decided to ban the use of GenAI for research, writing & creative work at our organization.

In fact, we make people sign an agreement saying that their research, analysis, writing, and creative work are *theirs* and not done by GenAI.

Peer review meltdown in one diagram.

Greater emphasis on glamour journals leads people to try their luck with mediocre papers. This drains the review pool (they often have to be re-reviewed elsewhere). That drops the accuracy of peer review, creating more incentive to submit mediocre papers…
