Hi-UCD (ultra-High Urban Change Detection) series datasets are designed for deep learning based urban semantic change detection.
- 2023/9/10 Hi-UCD mini is released.
- 2024/7/18 Hi-UCD is released.
The Hi-UCD mini dataset can be downloaded through the Google Drive link. Please submit a download request through the link and I will process your request as soon as possible.
The characteristics of Hi-UCD:
- 40800 pairs ultra-high resolution images (0.1 m) for Tallinn, Estonia.
- Focus on refined urban semantic change detection.
- Include 2 years of images, 9 land cover classes and 48 semantic change classes.
- Tasks that can be performed on this dataset: semantic segmentation, binary change detection, semantic change detection, etc.
The Hi-UCD dataset can be downloaded through the Baidu Drive link and OneDrive link.
If you want to get the test scores, please join our hosted benchmark platform: semantic change detection.
