Landscape is an area formed by the interactions between humans and nature, which bring various characteristics to the area. Landscape Character Assessment (LCA) methods enable more accurate description, mapping, and evaluation of features within the landscape. Also, landscape characterization and classification is facilitated by the advances of Geographic Information Systems (GIS), which constitute a very efficient tool for analysis and overlay mapping. This paper explores and tests an application of Landscape Character Assessment (LCA) methodology at a regional scale in Ziban region, Algeria, combining natural and cultural attributes using GIS. The first stage of overlay of attributes is followed by the verification of draft map involving a visual assessment on-site in order to develop the final classification and assessment describing each landscape character area and type. The study results show that Ziban region has a rich structure with diversified landscapes created by unique natural and cultural landscape values composed of 36 different character areas and 19-character types. The main contribution of this research consists in developing a typology for Ziban landscape and providing useful results for decision-making related to the future management of landscape character in the Algerian context, which has undergone strong pressure related to urbanization, industry, transport, desertification, and tourism.
