Major-TOM/Core-S2L2A-249k-Clay-v1_5
收藏资源简介:
该数据集包含预计算的图像嵌入,这些嵌入是基于Core-S2L2A-249k卫星影像子集,使用Clay v1.5基础模型生成的。Clay是一个开源的地球观测基础模型,采用Masked Autoencoder (MAE)架构,具有动态补丁嵌入功能。数据集以GeoParquet文件格式分发,包含1024维的嵌入向量以及相关的空间元数据。每个嵌入向量对应于一个Sentinel-2 L2A影像芯片,经过预处理和模型推理后生成。数据集适用于跨模态检索和其他地球观测应用。
This dataset contains pre-computed image embeddings for the Core-S2L2A-249k satellite imagery subset, generated using the Clay v1.5 foundation model. Clay is an open-source foundation model for Earth observation, using a Masked Autoencoder (MAE) architecture with dynamic patch embeddings. The dataset is distributed as a single GeoParquet file, containing 1024-dimensional embedding vectors along with spatial metadata. Each embedding vector corresponds to a Sentinel-2 L2A image chip, generated through preprocessing and model inference. The dataset is suitable for cross-modal retrieval and other Earth observation applications.
