Short summary
Monitoring our planet with satellites produces massive datasets too large for researchers to handle. We created a new global database that condenses 25 years of Landsat and MODIS observations into a highly efficient format (Analysis-ready embedding vectors) using AI. By reducing data size by over 340 times while maintaining high accuracy, we allow global studies to be run on standard PC. Makes planetary research accessible to everyone and helps us better track environmental changes over time.
