Full datasets with GEOTIFF metadata
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. Then read section 3 below to verify then recombine the parts into the full archive.

Download full data with metadata (part 2/ab) (~9.8GB)
Download full data with metadata (part 3/ac) (~9.8GB)
Download full data with metadata (part 4/ad) (~9.8GB)
Download full data with metadata (part 5/ae) (~9.8GB)
Download full data with metadata (part 6/af) (~2.3GB)
Recombined archive: xview2_geotiff.tgz (~51GB)
Building Transforms from XBD
If you are looking for mapping information related to the XBD dataset, use the link 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)
Datasets from the Challenge
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.
Download Challenge training set (~7.8 GB)
Download additional Tier3 training data (~17.3 GB)
Download Challenge test set (~2.6 GB)
Download Challenge holdout set (~2.6 GB)
2. Verify file integrity
SHA1 hashes are provided to verify integrity of your downloaded
files. Compute the SHA1 checksum of each downloaded file using a command
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.
3. Merge and unpack the files
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
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
TL;DR: Download, verify, merge, decompress.
Note: Stale links and interrupted downloads
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.
