收藏资源简介:
S2-100K数据集是一个用于训练SatCLIP模型的全球采样多光谱Sentinel-2 L2A图像块数据集。它包含100,000个256×256像素的图像块,每个图像块有12个波段(B01, B02, B03, B04, B05, B06, B07, B08, B8A, B09, B11, B12),数据类型为uint16,并且每个图像块都有对应的经度/纬度坐标。数据集的文件布局包括元数据文件、索引文件和分片存储的图像块文件。每个图像块以GeoTIFF格式存储,具有UTM区域坐标参考系统(CRS)和10米的分辨率。数据集的使用方法包括直接流式加载部分分片、将图像块与坐标配对以及下载整个数据集。数据集的原始来源是Microsoft Azure Blob Storage,本仓库是一个已验证完整的副本。数据集采用MIT许可证,与上游SatCLIP项目一致。
The S2-100K dataset is a re-hosted version of the dataset used to train the SatCLIP model. It consists of 100,000 globally sampled multi-spectral Sentinel-2 L2A image patches, each of size 256×256 pixels with 12 bands (B01, B02, B03, B04, B05, B06, B07, B08, B8A, B09, B11, B12) in uint16 format, along with longitude/latitude coordinates for each patch. The datasets file layout includes metadata files, index files, and sharded image patch files. Each patch is stored in GeoTIFF format with a UTM zone coordinate reference system (CRS) and 10-meter resolution. The dataset provides methods for streaming a few shards directly, pairing patches with their coordinates, and downloading the entire dataset. The original dataset was hosted on Microsoft Azure Blob Storage, and this repository is a verified-complete copy. The dataset is licensed under MIT, matching the upstream SatCLIP project.
