OpenEarthMap-SAR
收藏资源简介:
OpenEarthMap-SAR是由日本理化学研究所和东京大学联合创建的一个高分辨率合成孔径雷达(SAR)数据集,旨在支持全球土地覆盖制图。该数据集包含5033张1024×1024像素的图像,覆盖了日本、法国和美国的35个地区,提供了8类土地覆盖标签,包括裸地、草地、开发空间、道路、树木、水体、农业用地和建筑物。数据集通过预训练的OpenEarthMap模型生成伪标签,并部分手动标注以提高质量。该数据集适用于城市规划、环境监测、灾害响应和可持续发展等领域,旨在解决高分辨率SAR图像在复杂地理条件下的土地覆盖分类问题。
OpenEarthMap-SAR is a high-resolution Synthetic Aperture Radar (SAR) dataset jointly created by RIKEN and the University of Tokyo, aiming to support global land cover mapping. This dataset includes 5033 images with a resolution of 1024 × 1024 pixels, covering 35 regions across Japan, France and the United States, and provides 8 categories of land cover labels, namely bare land, grassland, developed space, roads, trees, water bodies, agricultural land and buildings. The dataset generates pseudo labels via a pre-trained OpenEarthMap model, with partial manual annotations added to improve annotation quality. This dataset is applicable to fields such as urban planning, environmental monitoring, disaster response and sustainable development, and is designed to address the land cover classification challenge of high-resolution SAR images under complex geographic conditions.
