Researchers have developed GroundSet, a new large-scale dataset designed to improve the spatial understanding capabilities of multimodal large language models in remote sensing. The dataset includes 3.8 million annotated objects across 510,000 high-resolution images, featuring 135 semantic categories and grounded in cadastral vector data. Evaluations show that while current models like Gemini struggle with zero-shot spatial reasoning in this domain, high-fidelity supervision using GroundSet effectively enhances standard architectures without requiring complex modifications.
