Download Due to Zenodo's file size limitations, we are releasing different parts of CBF and GBD in different versions. See the below for specific information: 1. China's first sub-meter building footprints (CBF) derived by deep learning: part1: version12 (v12), City 1 to 210, https://doi.org/10.5281/zenodo.10473278 part2: version13 (v13), City 211 to 356, https://doi.org/10.5281/zenodo.10475803 2. Global Building Dataset (GBD): This dataset comprises approximately 800,000 images(512*512) with diverse architectural styles worldwide. It can be served as training and test samples for building extraction in different regions globally. In order to enhance usability, we did not break the continuity of the image and published it in 1024*1024 size. Version description link v1 All labels.
