Applicability of 3DVE indicator for cultural heritage landscape management

Abstract

Uniformly control of the height of buildings owned by individuals to protect cultural heritage landscape causes social conflicts. Thus, it is necessary to introduce an indicator that can simultaneously evaluate the criteria for control of the height of buildings (CCBH) for urban development and cultural heritage landscape management. We developed 3D Visual Exposure (3DVE) as a useful indicator to review the validity of the CCBH around cultural heritage. By using the 3DVE, it was possible to calculate visibility and we succeeded in mapping the opportunity of view on 3D geospatial information and evaluating landscape variation with statistics through changing building heights around cultural heritage. We predict that the 3DVE presented in this study will have high utilization as an indicator for the cultural heritage landscape management.
