This map plots over 150 massacres of Australia's aboriginal people.
Researchers who worked on the project say it's the "most comprehensive map yet" on the subject. The map covers massacres in the country from 1788 to 1872 during the frontier wars when the British colonized Australia.
Massacres — defined as six or more deaths — were confirmed using evidence, like accounts from Aborigines and settlers.
Researchers say the current estimate is low and that there are likely more to add.
Some say it's important to get evidence-based data on this topic because it's largely been understudied.
