This paper aims to present the structure of landscape interpretation and reconsider the concept of landscape by depicting the process by which landscape emerges as observer-specific “meaning”. For this purpose, we will focus on the existence of “knowledge,” which is said to have the function of directing human consciousness and encouraging the assignment of meaning, and grasp the relationship between its reality and landscape interpretation. By approaching the reality of “knowledge” and structurally understanding the interpretation of landscape, we empirically demonstrated that landscape as a phenomenon is momentarily “constructed” by the observer and that “environmental knowledge” drives it.
