Ida-BD: pre- and post-disaster high-resolution satellite imagery for building damage assessment from Hurricane Ida

Ida-BD is a dataset with 87 pre- and post-disaster satellite imagery pairs with a very high resolution (0.5m/pixel) from Hurricane Ida 2021 in Louisiana, USA. Ida-BD was obtained from the WorldView-2 (WV2) satellite with very high-resolution images taken in Nov. 2020 and Jul. 2021 for pre-disaster and Sep. 2021 for post-disaster. The satellite imagery was collected close to New Orleans city in Louisiana, USA, one of the most impacted areas during Hurricane Ida in late Aug. 2021. Similar to the xBD dataset, we use polygons to represent building segments and provide four damage categories. All annotations were done by the in-house team with quality control.

Ida-BD是一款包含87组灾前与灾后卫星影像对的数据集，影像分辨率高达0.5米/像素，数据采集自2021年美国路易斯安那州飓风艾达（Hurricane Ida）受灾区域。该数据集通过世界视图-2（WorldView-2，WV2）卫星获取，其中灾前影像采集于2020年11月与2021年7月，灾后影像采集于2021年9月。卫星影像的采集区域位于美国路易斯安那州新奥尔良市周边，该区域是2021年8月末飓风艾达受灾最严重的区域之一。与xBD数据集类似，本数据集采用多边形标注建筑物地块，并划分了四类损毁等级。所有标注工作均由内部团队完成并经过质量管控。
