高分辨率卫星图像标注数据集（xBD）

“xBD”包含了大约70万个建筑物在8种不同的自然灾害之前和之后的卫星图像，包括地震、野火、洪水和火山爆发。它覆盖了约5000平方公里的地区，包括印度和非洲的洪水、老挝和巴西的大坝倒塌以及加利福尼亚和希腊历史性的致命火灾。 If you are seeking the latest and most complete xView2/XBD datasets, use the links below. Downloads are provided in multiple parts; the full dataset and metadata occupy approximately 51GB (compressed) on disk. Download each file separately using the links below.

This download doesn't contain any of the images, just metadata around the location of the image and its origin. Download Geotransforms (~500 KB) SHA1: 0b3bda08084ac102d8b540261ebbba0094203a2f If you are downloading data for the first time, use the links above to obtain the full datasets and metadata. Now that the xView2 Challenge is complete, the downloads below are provided for continuity only. For returning users or those who are looking to replicate historical or academic results, those files are still available for download. The files above contain the same imagery as the files below; only the formatting and metadata are different. Please be respectful of bandwidth and download only the appropriate version.

Compute the SHA1 checksum of each downloaded file using a command like shasum -a 1 FILENAME , then compare the result computed from your local file to the SHA1 strings above. If the hashes match, then your file is good. If your result does not match the SHA1 hashes above, something has gone wrong with your download and you should re-download, perhaps using a more reliable connection. Downloads are provided as GZIP tarball archives. The full dataset with metadata is provided in parts. Download and verify each file. After all downloads have completed and all your hashes match the values above on this page, you can recombine the parts using the following command: cat xview2_geotiff.tgz.part-a? > xview2_geotiff.tgz to obtain the full archive. Finally, decompress each .tgz or .tar.gz file using a command like: tar -xvzf FILENAME To maximize download speed, your download links are customized to stream data from a nearby server. If your download is interrupted, you may need to reload this page to obtain fresh download links. Please be respectful of download bandwidth, and re-download data only when necessary. We have gotten feedback that some unzip programs report errors on large archives. Unfortunately, this is due to various non-standard archive protocols. If you get such an error (perhaps while using a tool like 7-zip), try using tar or the archive/unzip tool packaged with your OS.
