Abstract: Like other subjects in iconographic studies, map has been criticized for its subjective selectivity in representing landscapes, making design disciplines to explore how this selectivity can be used to more effectively intervene contemporary dynamic landscapes. In order to clarify the ambiguity in such explorations’ methodology, this paper made a comparative analysis of four individuals and teams who have conducted mapping-based investigations of contemporary landscapes. The findings show that contradictions in ordinary landscapes were the focus of research, and subjective experience of landscapes were emphasized in relevant data collection processes. Maps served as the medium for integrating multiple data types, with specific techniques differing according to site conditions and aesthetic preferences. Some researchers sought design practice opportunities by first expanding their social influence, others started with small things by means of micro spatial regeneration.
