Recording Every Moment of Earth? The Arrival of 'Virtual Satellites', the AI That Sees Through Clouds

Imagine if the map app you use every day did more than just give you directions. What if it could tell you in real-time how the trees in your neighborhood forest have grown over the past five years, how much crops in a neighboring country have withered due to drought, or even what’s happening under a dense jungle hidden by thick clouds? It would be like having a giant microscope focused on the entire planet.

Until now, we have observed Earth through “photos” taken by satellites in space. However, satellite imagery is heavily influenced by the weather. Even a little bit of cloud cover can hide the surface, making them useless, and a single photo makes it difficult to understand the complex causes of changes happening on that land. Google DeepMind recently announced a new artificial intelligence model, ‘AlphaEarth Foundations’, which overcomes these limitations by understanding and reconstructing all changes on Earth as data.

This technology is more than just a camera. Christopher Brown, a research engineer at DeepMind, describes it as a ‘Virtual Satellite that can map Earth anytime, anywhere.’ Google launched an AI model that functions like a virtual satellite – here’s how it works I’ll explain, like a smart friend telling a story, how AI is creating a “sophisticated replica” of our planet and why this is an important change for our lives.

Why It Matters

The Earth we live on is changing rapidly at this very moment. Climate change is melting Arctic glaciers, causing unexpected wildfires, and shifting crop harvest times. However, the Earth is so vast and complex that it is nearly impossible for humans to monitor it individually or perfectly track those minute changes with conventional satellite imagery alone.

AlphaEarth Foundations integrates vast amounts of observation data scattered across the globe. Through this, it creates a ‘Digital Twin’ of Earth (a virtual implementation of a real object using software) that reacts in real-time like a living organism.

This digital twin grants us three major capabilities:

1. Guardian of Environmental Protection: It captures indiscriminate deforestation in jungles or the spread of marine pollution much faster and more accurately than the human eye.
2. Forecaster for Agriculture: By analyzing the health of farmland worldwide, it helps predict and prepare for food crises in advance.

3. Evidence of Climate Change: By showing precisely how the Earth has changed over the past several years with detailed figures, it supports scientists in creating better environmental policies. [AlphaEarth Foundations: A “virtual satellite” to map…

The Explainer: Seeing Earth in 64 Colors

The way AlphaEarth observes the world is completely different from our eyes. To understand this magical technology, let’s use two analogies.

First Analogy: A Painter with 64 Special Glasses

Our eyes see the world by combining three primary colors: red, green, and blue (RGB). However, AlphaEarth uses a whopping 64 dimensions (criteria for classifying information) when processing data. AlphaEarth Foundations helps map our planet in unprecedented detail

To put it simply, if a regular painter paints with only three colors of paint, AlphaEarth uses 64 colors that include special information such as infrared rays invisible to humans, soil moisture, and the rough texture of the surface. Researchers selected the three most essential parts of this complex data and converted them into colors familiar to our eyes, completing a precise map that even non-experts can understand at a glance.

Second Analogy: A Super-Powered Magnifying Glass That Sees Through Fog

The biggest enemy of satellite photography is clouds. If clouds cover an important observation point, the ground becomes pitch black. However, AlphaEarth has the ‘ability to infer the truth beyond the clouds.’

In other words, in regions where clouds are frequent year-round, such as Ecuador in South America, it was impossible to properly check farmland with conventional satellites. However, AlphaEarth combines past records with current minute signals to draw the appearance of the land hidden behind clouds in detail, much like a local resident who knows the way perfectly even on a foggy day. AlphaEarth Foundations helps map our planet in unprecedented detail AI fills in the missing information itself to complete the map.

Difference in Precision: Sees Areas as Small as a Volleyball Court

How detailed is the map that AlphaEarth creates? According to data released by DeepMind, each pixel (the smallest unit of an image) of the map represents a 10x10 meter area of the actual surface. AlphaEarth.ipynb - Colab

A 10-meter square is roughly a bit larger than one side of a volleyball court. It is a truly remarkable technical advancement to be able to track changes in every corner of our neighborhood playground on an annual basis while covering the entire vast Earth.

Where We Stand

Currently, Google DeepMind has released a massive dataset to the world, including annual satellite embeddings (data converted into a sequence of numbers for computers to easily understand) from 2017 to 2024. AlphaEarth.ipynb - Colab

This data is already active in the field. It is being used to observe how ice in Antarctica is changing or to predict harvest times for Ecuadorian farmland that was hidden by clouds. Google launches ‘AlphaEarth Foundations,’ an AI for mapping the… We have reached a stage where vast observation information pouring in from all over the world is woven into one giant stream, dynamically showing how the Earth breathes and evolves.

What’s Next

In the future, thanks to this ‘virtual satellite,’ we can look forward to a world like this:

• Disaster Response Faster Than Light: When a flood or wildfire occurs, it can accurately identify scenes hidden by smoke or clouds, helping rescuers travel the safest route.
• Smart Personalized Agriculture: Precision agriculture will become possible, analyzing the soil condition of a specific area and informing farmers that "now is the optimal time to sow seeds."
• Unlocking the Secrets of Earth’s Ecosystems: By proving through data how global ecosystems are connected, we will be able to find and solve the root causes of environmental pollution that we were previously unaware of. AlphaEarth Foundations helps map our planet in unprecedented detail

AI’s Take

AlphaEarth is not just an AI that draws pretty maps. It is an ambitious challenge by Google DeepMind to understand the ‘massive system that is Earth’ itself by weaving hundreds of millions of fragmented data points into one giant intelligence. We look forward to AI acting as a reliable ‘Earth doctor,’ checking and managing the health of our planet by looking into every corner, even the blind spots that human eyes cannot reach.
