With climate change predicted to increase the likelihood of landslide events, there is a growing need for rapid landslide detection technologies that help inform emergency responses. Synthetic Aperture Radar (SAR) is a remote sensing technique that can provide measurements of affected areas independent of weather or lighting conditions. Usage of SAR, however, is hindered by domain knowledge that is necessary for the pre-processing steps and its interpretation requires expert knowledge. We provide simplified, pre-processed, machine-learning ready SAR datacubes for four globally located landslide events obtained from several Sentinel-1 satellite passes before and after a landslide triggering event together with segmentation maps of the landslides. From this dataset, using the Hokkaido, Japan datacube, we study the feasibility of SAR-based landslide detection with supervised deep learning (DL). Our results demonstrate that DL models can be used to detect landslides from SAR data, achieving an Area under the Precision-Recall curve exceeding 0.7. We find that additional satellite visits enhance detection performance, but that early detection is possible when SAR data is combined with terrain information from a digital elevation model. This can be especially useful for time-critical emergency interventions. Code is made publicly available at https://github.com/iprapas/landslide-sar-unet.

通过卫星图像和机器学习对行星进行大规模分析是一个梦想，这一梦想不断受到难以获取高度代表性的高分辨率图像的成本的阻碍。为了纠正此问题，我们在这里介绍WorldStrat数据集。 The largest and most varied such publicly available dataset, at Airbus SPOT 6/7 satellites' high resolution of up to 1.5 m/pixel, empowered by European Space Agency's Phi-Lab as part of the ESA-funded QueryPlanet project, we curate nearly 10,000独特位置的SQKM，以确保全世界所有类型的土地用途分层：从农业到冰盖，从森林到多种城市化密度。我们还丰富了通常在ML数据集中代表不足的地点的人：人道主义兴趣的地点，非法采矿地点以及有风险的人的定居点。我们以10 m/pixel的可自由访问的下分辨率Sentinel-2卫星的多个低分辨率图像为暂时匹配每个高分辨率图像。我们伴随着该数据集的开源Python软件包，以：重建或扩展WorldStrat数据集，训练和推断基线算法，并使用丰富的教程学习，所有这些都与流行的EO-Learn Toolbox兼容。我们特此希望能够促进ML在卫星图像中的广泛应用，并可能从免费的公共低分辨率Sentinel2图像中发展出昂贵的私人高分辨率图像所允许的相同的分析能力。我们通过训练并发布了有关多帧超分辨率任务的几个高度计算效率的基线来说明这一特定点。高分辨率空中图像是CC BY-NC，而标签和Sentinel2图像为CC，而BSD下的源代码和预训练模型。该数据集可从https://zenodo.org/record/6810792获得，并在https://github.com/worldstrat/worldstrat上获得。

高分辨率遥感图像用于广泛的任务，包括对象的检测和分类。然而，高分辨率图像昂贵，而较低的分辨率图像通常是可自由的可用的，并且可以由公众用于社会良好应用范围。为此，我们使用从Spacenet 7挑战的PlanetsCope图像策划多个频谱多图像超分辨率数据集作为高分辨率参考和与低分辨率图像相同的图像的多个Sentinel-2重新定位。我们介绍了将多图像超分辨率（MISR）应用于多光谱遥感图像的第一个结果。此外，我们还将辐射级一致性模块引入MISR模型，以保持哨声-2传感器的高辐射分辨率。我们表明MISR优于一系列图像保真度指标的单图像超分辨率和其他基线。此外，我们对建筑描绘的多图像超分辨率的效用进行了第一次评估，显示利用多个图像导致这些下游任务中的更好的性能。
