EXPLORATION OF THE METHOD OF TRACING THE BOUNDARY AND PATTERN OF THE IMPERIAL GARDEN BY FOLLOWING THE TRACES OF HISTORY – TAKING CHANGCHUN GARDEN AS AN EXAMPLE

Abstract. In the process of digital restoration of cultural heritage, for the disappeared royal gardens, where information is relatively scarce, the process of accurate digital restoration usually encounters a problem of how to effectively use the fragmented and limited historical and status quo information for discernment, to achieve accurate digital alignment restoration of the disappeared royal gardens in the region, and to complete the overall digital restoration of boundaries and patterns. Taking Changchun Garden as an example, this paper uses recent status quo mapping, aerial photography and current status quo structures as the basis, historical archival materials, style house plans, early mapping, early aerial photography and various historical documents as the starting point for the credibility and priority of various materials, and uses the iconic remaining information of key locations, such as buildings, water systems and fences, through historical traces, relative positions and proportional relationships. The identification of the 'line' is done by using the 'point' to determine the location of the wall in the east, north, west and south directions, thus defining the boundary and pattern of the historical Changchun Garden. This approach is based on the disappearing royal gardens and the digital restoration process can be effective in completing the task of solving problems and giving ideas and directions to those working in the relevant fields.
