Megalith-CC0
A CC0-filtered version of the Megalith-10m dataset. The images have also been persisted to an independent public S3 bucket, supported by the AWS Open Data Registry program, for durability.
Why filter by CC0?
The images in Megalith-10m, having been gathered from Flickr, have attached licenses of CC0 and public domain. However, it is not clear if users assigning the public domain license to their works understand the implications of the public domain… See the full description on the dataset page: https://huggingface.co/datasets/Spawning/megalith-cc0.StockImages-CC0
