Sentinel-1 SAR data
收藏资源简介:
该数据集包含118张由Sentinel-1卫星在2014年10月至2017年4月期间获取的SAR图像,这些图像覆盖了挪威北部两个山区。图像经过辐射定标、下采样和地理编码处理,并转换为分贝值。数据集通过专家手动标注产生了二进制分割掩模,用以区分雪崩和非雪崩像素。该数据集用于训练深度学习模型,以实现对雪崩的精确检测和分割,对于研究雪崩监测和预警具有重要意义。
This dataset comprises 118 SAR images acquired by the Sentinel-1 satellite between October 2014 and April 2017, covering two mountainous regions in northern Norway. The images have undergone radiometric calibration, downsampling, and geocoding, and been converted to decibel values. Binary segmentation masks were manually annotated by experts to differentiate between avalanche and non-avalanche pixels. This dataset is employed for training deep learning models to achieve accurate avalanche detection and segmentation, and holds substantial significance for research on avalanche monitoring and early warning.
