Remote sensing spatiotemporal prediction aims to infer future trends from historical spatiotemporal data, e.g., videos and time series images, has a broad application prospect in many fields. The foundation model is a promising research direction for spatiotemporal information mining because of its robust feature extraction capability, and has made rapid progress in natural scenes. Nevertheless, due to the spatially multi-scale and temporally multi-scale properties in remote sensing data, these methods still encounter bottlenecks when applied to remote sensing. Therefore, we propose a foundation model for remote sensing spatiotemporal prediction via spatiotemporal evolution decoupling, abbreviated as RingMo-Sense. Considering spatial affinity, temporal continuity, and spatiotemporal interaction, we construct spatial, temporal, and spatiotemporal triple-branch prediction networks. Specifically, we use parameter-sharing and progressive joint training strategies to achieve stable long-range prediction and parameter reduction simultaneously. In addition, we build a remote sensing spatiotemporal dataset by collecting various remote sensing videos and time series images. The experimental results on six downstream spatiotemporal tasks demonstrate that the proposed model yields competitive performance.
