Abstract

xView is a new large-scale dataset for the advancement of object detection techniques and overhead object detection research. This satellite imagery dataset enables research progress pertaining to four key computer vision frontiers. We utilize a novel process for geospatial category detection and bounding box annotation with three stages of quality control. Our data is collected from WorldView-3 satellites at 0.3m ground sample distance, providing higher resolution imagery than most public satellite imagery datasets. We compare xView to other object detection datasets in both natural and overhead imagery domains and then provide a baseline analysis using the Single Shot MultiBox Detector. xView is one of the largest and most diverse publicly available object detection datasets to date, with over 1 million objects across 60 classes in over 1,400 km2 of imagery.

The xVIEW dataset has been fully described in a paper which is freely available via arXiv.org: We encourage you to download and read the paper for more details.

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.

ZIP and TGZ files contain identical data, the only difference is the compression software used to create the archive. The size of correponding ZIP/TGZ files is approximately equal, choose the one that is more convenient for you. Please do not waste bandwidth downloading both.

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.
