Foreign digital landscape research has experienced long-term and complete system construction and the expansion and in-depth research field. A comprehensive and systematic review of it has important reference value for domestic digital landscape research. Using the scientific metrology software CiteSpace, the foreign literature in the SCI core journals from 2000 to 2020 in the “Web of Science” database are used as the research object to show the national differences, institutional distribution, disciplinary cooperation networks, research trends, knowledge base and hot frontiers of international digital landscape research. Studies have shown that: (1) The development process of digital landscape abroad is complete. Scholars in Europe and the United States have built the early knowledge framework of knowledge networks. Chinese academic circles started late but have a rapid development momentum; (2) The research direction is diverse, the network system is complete, and the methods are used for reference. The cutting-edge technologies and model methods of multiple disciplines have obvious characteristics of interdisciplinary integration. (3) The research hotspots of various stages in the field of digital landscape are very different. At this stage, research on environmental and climate improvement based on the comfort of human groups, new information sources represented by social media and data in landscape analysis and research LiDAR is a hot research field.
