ResumenThe interpretation of archaeological features in LiDAR-derived digital terrain models is very dependent on visualization techniques. Different methods have been proposed to highlight microtopographies, since the >simple> hillshade, which can be easily computed in any GIS software, to more complex ones like Local Relief Models (LRMs). LRMs are an interesting visualization technique that allow us to discriminate between positive and negative microtopographies at a local scale and that can be easily combined with other data sources, maintaining the original elevation units and representing real changes in elevation rather than calculations based on steepness and direction of slope or exposure to light. This study analyzes the potential of mathematical morphology to generate LRMs. In this sense, a morphological approach was developed to map on an automated way positive and negative microtopographies.
