• 2021/12/13, Pre-trained urls for HRNet have been updated.

• 2021/12/10, LoveDA has been included in Torchgeo.

• 2021/11/30, The contests have been moved to new server: LoveDA Semantic Segmentation Challenge, LoveDA Unsupervised Domain Adaptation Challenge.

• 2021/11/11, LoveDA has been included in MMsegmentation. 🔥🔥 The Semantic Segmentation task can be prepared follow dataset_prepare.md.🔥🔥

1. 5987 high spatial resolution (0.3 m) remote sensing images from Nanjing, Changzhou, and Wuhan
2. Focus on different geographical environments between Urban and Rural
3. Advance both semantic segmentation and domain adaptation tasks
4. Three considerable challenges:
   • Multi-scale objects
   • Complex background samples
   • Inconsistent class distributions

If you use LoveDA in your research, please cite our coming NeurIPS2021 paper.

The LoveDA dataset is released at Zenodo and Baidu Drive Code: 27vc

You can develop your models on Train and Validation sets.

Category labels: background – 1, building – 2, road – 3, water – 4, barren – 5,forest – 6, agriculture – 7. And the no-data regions were assigned 0 which should be ignored. The provided data loader will help you construct your pipeline.

Submit your test results on LoveDA Semantic Segmentation Challenge, LoveDA Unsupervised Domain Adaptation Challenge. You will get your Test scores smoothly.

Feel free to design your own models, and we are looking forward to your exciting results!
