x-oscd

The Onera Satellite Change Detection dataset addresses the issue of detecting changes between satellite images from different dates.
<br>
It comprises 24 pairs of multispectral images taken from the Sentinel-2 satellites between 2015 and 2018. Locations are picked all over the world, in Brazil, USA, Europe, Middle-East and Asia. For each location, registered pairs of 13-band multispectral satellite images obtained by the Sentinel-2 satellites are provided. Images vary in spatial resolution between 10m, 20m and 60m.
<br>
Pixel-level change ground truth is provided for all 14 training and 10 test image pairs. The annotated changes focus on urban changes, such as new buildings or new roads. These data can be used for training and setting parameters of change detection algorithms.

ONERA卫星变化检测数据集（Onera Satellite Change Detection Dataset）旨在解决不同时期卫星影像间的变化检测任务。
该数据集包含2015年至2018年间由哨兵-2号卫星（Sentinel-2）获取的24组多光谱影像对。影像采集点遍布全球，涵盖巴西、美国、欧洲、中东及亚洲区域。针对每个采集点位，均提供由哨兵-2号卫星获取的13波段多光谱卫星影像配准对，其空间分辨率覆盖10米、20米与60米三个档位。
针对全部14组训练影像对与10组测试影像对，均提供了像素级变化地面真值标注。标注的变化区域聚焦于城市变化场景，例如新建建筑或新修筑道路。该数据集可用于训练变化检测算法并调试其参数。
