EarthworkSat 7K A satellite imagery dataset for finding earthwork on construction sites, and for estimating its volume. About 7,400 annotated earthwork instances in 14 cities across Europe and Asia. The images are Google Earth screen captures at a pixel size of about 0.13 m, taken between 2018 and 2025. A separate set of 505 instances at 14 further locations is paired with public airborne LiDAR, so each of those instances has a reference volume in cubic metres. What is in the repository Tiles and masks pair by filename: images/CPH/src CPH 2019 08 25 0001.jpg goes with masks/CPH/src CPH 2019 08 25 0001 mask.png . The split is by city: nine cities train, Oslo and Istanbul validate, and Copenhagen, Munich and Milan are the test set. The test cities are never seen in training, so the benchmark measures how a model transfers to a new city. Volume For the 505 volume instances the mask marks the deposit and the CSV row gives its reference volume, computed from national airborne LiDAR by integrating height above the lowest point inside the boundary. Each CSV also has a split column: finetune if the instance was used to adapt the segmentation model to the volume imagery, heldout if it was k…
