Today, detection of cultural heritage in forests usually is carried out by means of interpretation of terrain models generated from laserdata.Knowledge of which factors that affect the interpretation results is therefore important. This project’s main goal is to assess the effects of point density and smoothing of terrain models on the detection success of cultural remains in forests. The analyzes are based on data from 9 square blocks of 0.25 square kilometers where an intensive field effort was carried out by people with archaeological expert competence to establish a ground truth. Then four experienced archaeologists interpreted nine different DTMs with different properties from each block using a visualization software. The analysis based on a randomized complete block design will reveal the effects of point density and smoothing.
