TorchGeo 0.6 marks a significant step forward in geospatial machine learning by offering new datasets, data modules, and pre-trained models for satellite image analysis. Over 11 months, 23 contributors worked on this update, which introduces groundbreaking tools for deep learning applications in Earth observation.
TorchGeo’s integration with Microsoft, specifically through the PyTorch ecosystem, enhances its power. Microsoft supports PyTorch, the deep learning framework that TorchGeo is built on.
Background and Purpose
The growing need for geospatial machine learning is driven by the thousands of satellites orbiting Earth, capturing vast amounts of data. Traditionally, deep learning models required millions of manually labeled images from specific satellite sensors to function effectively. Even self-supervised learning, which eliminates the need for labels, still demanded a large volume of sensor-specific images. This posed challenges for using newly launched or commercial satellites.
TorchGeo 0.6 solves these problems by providing models that can work with any satellite imagery, regardless of whether the model was trained on it. This makes it more accessible and flexible, particularly for newly launched or expensive sensors.
