More than 6,500 volunteers have supported the accurate identification of approximately 1,000 prehistoric burial mounds in the Netherlands in just four months, proving the value of involving volunteers in archaeology.

In 2018, the Heritage Quest project was launched to harness the power of citizen scientists, utilizing crowd-sourcing to identify archaeological features on lidar imagery of the central Netherlands.

Through the involvement of thousands of people online, prehistoric burial mounds were identified across the region in a short amount of time. However, the accuracy of crowd-sourced data has been questioned in the past, as the majority of volunteers are not professional archaeologists.

"While the volume of data exceeded our expectations, we faced a key challenge common to large citizen science projects: how reliable are the detections made by volunteers?" states lead author of the research, Dr. Quentin Bourgeois from Leiden University.

To assess the accuracy of the data, the authors performed a ground-based survey of 380 sites identified during the study, examining them in person to determine whether they were in fact prehistoric barrows. Their results are published in the journal Antiquity.
