🌍 GeoChrono: Long-Term Temporal Understanding in Remote Sensing

GeoChrono is a multimodal LLM for reasoning about multi-temporal satellite image sequences. Upload a chronological sequence of remote sensing images (each labeled with its year), ask a question, and the model will reason about land cover changes and temporal patterns.
