WHU-CD数据集（未经网站修改）

1. 简介该数据集聚焦地震后重建区域的变化分析，涵盖 2011 年 6.3 级地震受灾及后续重建区域，包含 2012 年 4 月获取的航空图像（覆盖 20.5 平方公里、12796 座建筑物）和 2016 年对应区域数据（16077 座建筑物）；通过 30 个 GCP 手动地理校正，精度达 1.6 像素，提供 “before_change”（2012 年，用于训练地震后未大规模重建前的 CNN 建筑提取模型）和 “after_change”（2016 年，用于训练同期 CNN 模型）两个 100% 重叠的子数据集，同时公开建筑矢量图、栅格地图及对应图像，便于测试变化检测算法效果

1. Dataset Overview: This dataset focuses on change analysis of post-earthquake reconstruction areas, covering regions affected by the 2011 Mw 6.3 earthquake and their subsequent post-disaster reconstruction zones. It includes aerial imagery acquired in April 2012 (spanning 20.5 square kilometers, with 12,796 buildings) and corresponding regional data from 2016 (covering 16,077 buildings). All imagery was manually georectified using 30 Ground Control Points (GCPs), achieving a positional accuracy of 1.6 pixels. The dataset provides two fully overlapping sub-datasets named "before_change" (from 2012, used for training CNN-based building extraction models prior to large-scale post-earthquake reconstruction) and "after_change" (from 2016, used for training concurrent CNN models). Additionally, building vector maps, raster maps, and their corresponding imagery are publicly released to facilitate the evaluation of change detection algorithms.
