Satellite images are crucial for applications like environmental monitoring, disaster management, and urban planning [1, 2]. It is still difficult for non-experts to interpret such complex images. To solve this, we propose a Visual Question Answering (VQA) system specifically for satellite images, allowing users to pose natural language queries and get image-based responses. Our method combines CNNs for visual feature extraction, BERT-based models for understanding questions, and a multimodal fusion mechanism. Trained on RSVQA and Sentinel-2 datasets, the system attained more than 92% accuracy on tasks such as flood identification, land cover classification, and urban analysis. Through this research, access to geospatial intelligence for planning, monitoring, and emergency response is improved.

摘要

Satellite images are crucial for applications like environmental monitoring, disaster management, and urban planning [1, 2]. It is still difficult for non-experts to interpret such complex images. To solve this, we propose a Visual Question Answering (VQA) system specifically for satellite images, allowing users to pose natural language queries and get image-based responses. Our method combines CNNs for visual feature extraction, BERT-based models for understanding questions, and a multimodal fusion mechanism. Trained on RSVQA and Sentinel-2 datasets, the system attained more than 92% accuracy on tasks such as flood identification, land cover classification, and urban analysis. Through this research, access to geospatial intelligence for planning, monitoring, and emergency response is improved.
