02 / The methodFrom extent to review

One area.
Several ways to see it.

TerraTrace turns national terrain data into a structured review workflow. A ranked candidate is a prompt to investigate, never a confirmed archaeological site.

Detection draws on published work in Polish ALS archaeology, including Bakuła, Ostrowski and Zapłata (2014), Banasiak and others (2022), and Jakubczak, Tyszkiewicz and Leloch (2025). TerraTrace packages that approach as a reviewable workflow.
