Geomorphology of the Arrabida Chain (Portugal)

Geomorphological maps are crucially important in geomorphology studies, allowing the representation of topographic and geological data in an interpretative, dynamic and appealing way. In this paper, a medium-scale (1:70,000) geomorphological map is presented with the objective of facilitating the analysis and interpretation of the Plio-Quaternary landscapes of the Arrabida Chain, central-west Portugal. The map results from the combination of field and laboratory techniques, including aerial-photo interpretation, digital terrain data analysis and the morphometric study of landforms.
