Major-TOM/Core-S2L2A-249k-OlmoEarth-Base
收藏资源简介:
该数据集包含了针对Core-S2L2A-249k卫星影像子集的预计算图像嵌入,这些嵌入是通过OlmoEarth-Base基础模型生成的。OlmoEarth是一个地球系统基础模型,专门用于处理Sentinel-2 L2A和6个派生地理空间地图的数据。数据集采用GeoParquet文件格式分发,包含了768维的特征向量、时间戳、产品标识符、地理空间元数据等信息。数据集适用于跨模态检索,可以与EarthEmbeddingExplorer网络应用程序配合使用。
This dataset contains pre-computed image embeddings for the Core-S2L2A-249k satellite imagery subset, generated using the OlmoEarth-Base foundation model. OlmoEarth is an Earth-system foundation model trained on Sentinel-2 L2A and 6 derived geospatial maps. The dataset is distributed as a single GeoParquet file, including 768-dimensional feature vectors, timestamps, product identifiers, geospatial metadata, etc. It is suitable for cross-modal retrieval and can be paired with the EarthEmbeddingExplorer web application.
