收藏资源简介:
FireWatch SFT数据集是一个包含与野火相关的Sentinel-2卫星图像对(火灾前后的时间序列图像)的数据集。通过dNBR(差异归一化燃烧指数)生成变化掩膜,并为每个图像块生成变化描述文本行和(存在区域时的)带有归一化边界框的接地行。数据集分为训练集(187条)、验证集(空)和测试集(48条)。数据集布局包括JSONL文件、PNG图像块和元数据JSON文件。数据集的生成和处理依赖于特定的CLI命令和环境变量设置。
FireWatch SFT is a dataset containing temporal Sentinel-2 image pairs (pre/post around a wildfire-relevant event date) over a fixed AOI. The dataset uses dNBR-style burn signal to drive a change mask and emits a change caption row for each tile, along with a grounding row with normalized bounding boxes when regions exist. The dataset is split into train (187 entries), validation (empty), and test (48 entries) sets. The dataset layout includes JSONL files, PNG image chips, and metadata JSON files. The generation and processing of the dataset rely on specific CLI commands and environment variables.
