Object-based landform delineation and classification from DEMs for archaeological predictive mapping

► Archaeologists currently rely on visual interpretation of DEMs to analyse landform. ► Object-based image analysis (OBIA) is a new tool to extract landform from DEMs. ► OBIA was tested to see whether it could match visual interpretation. ► The results show that OBIA produces good results, is quicker and more objective. ► A contextual framework for classification of landform still needs to be developed.
