GeoRoPE: Ground-Aware Rotary Adaptation for Remote Sensing Foundation Models

GeoRoPE is a proposed spatial adaptation method for remote-sensing foundation models (RSFMs) that addresses scale mismatches during downstream adaptation by providing ground-aware positional corrections. It employs Geo-Coordinate Calibration (GCC) to rescale token-grid offsets based on ground distances and Geo-Frequency Calibration (GFC) to adjust RoPE frequencies for scene-specific adaptations. This lightweight adapter enhances cross-resolution robustness and improves scale-sensitive representation learning in RSFMs, making it a significant advancement for practitioners working with heterogeneous remote sensing data.
