     "description": "This dataset is designed for the task of building detection in urban environments using image segmentation. It includes high-resolution aerial or satellite images of urban areas, paired with corresponding segmentation masks that delineate building footprints. The dataset is structured into training, validation, and test sets, and is suitable for developing and evaluating models for urban climate analysis and automated building detection.",
