Google Launches AI System That Uses Trillions of Images to Map Earth’s Changing Surface

In a technological leap for geospatial science, Google has introduced an artificial intelligence model capable of integrating trillions of images and data points into dynamic, global maps that document changes in land and shallow waters at any location or time. The system, which researchers compare to a “virtual satellite,” promises to streamline the laborious task of analyzing satellite data and unite disparate sources such as satellite imagery and radar. While experts praise the scale and potential efficiency gains, they urge Google to be more transparent about the model’s operations and emphasize that scientists will need to validate the accuracy of any derived maps independently.
