In this study, we investigated which types and categories of cultural remains that were most likely to be detected and classified correctly in a manual interpretation of digital terrain models derived from laser scanner data. Not surprisingly, large remains were easier to detect than small ones, and remains with a distinct geometric shape were easier to find than those with an irregular shape. The two types of cultural remains that had the highest joint probability to be both detected and correctly classified were charcoal kilns and grave mounds. However, hollow roads were always classified correctly once detected, but many were not found during the interpretation.
