1. Object Classes

Here are the parent and child denominations for all 60 object classes in xView. Parent classes are at the headings of each column. The only exception is the last column 'None', which corresponds to classes that have no parent.

Full satellite images gathered from DigitalGlobe’s WorldView 3 (WV3) satellites span a total area of over 1,400 square kilometers at 0.3 meter ground sample distance (GSD) resolution. The dataset was prepared in ways that are typical for satellite imagery, including ortho-rectification, pan-sharpening, RGB dynamic range adjustment, and atmospheric correction. xView contains more than 1 million labeled instances across 60 object categories. The fields in the geoJSON files include:

Field Name	Description
TYPE_ID	The bounding box label class ID
CAT_ID	DigitalGlobe's unique ID for image strips
IMAGE_ID	The image chip filename on which a feature is marked
BOUNDS_IMCOORDS	Bounding box in pixel coordinates [xmin, ymin, xmax, ymax] of the image chip in which it is marked
COORDINATES	Coordinates in longitude-latitude form for bounding box points

The GeoTIFF files are broken into two sets: RGB and 8-band. The 8-band set contains 8-band multispectral GeoTIFF images labeled as image_id.tif where image_id is a unique integer. Similarly, the RGB set containes pan-sharpened 3-band RGB GeoTIFF images with the same naming convention.

The dataset was segmented into three sets, training, validation, and test, which have roughly 60, 20, and 20 percent of the images respectively. Restrictions were placed on the splits so that each set had enough instances of each category to perform a fair analysis. As with many challenges, all participants will have access to the train and validation images, but during the challenge, labels are provided for only the train dataset. The private test set will be used to evaluate final submissions after the Challenge deadline.

Verify file integrity

SHA1 hashes are provided to verify integrity of your downloaded files. Compute the SHA1 checksum of your 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 they are identical, then your file is good.

ZIP decompression errors

If you encounter warnings or errors about offsets or "extra bytes at beginning of file" when decompressing these zip files, this is a known issue for decompressing files over 4 GB. The source files have been verified, but you may need to upgrade your decompression tool. On Windows, please use 7zip to decompress. On Mac, please use 7zip or The Unarchiver. On Linux you may need to upgrade your `unzip` binaries. Alternatively, download the gzipped tarball files (and decompress using a command like tar -xvzf FILENAME ).

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.
