LANDSCAPE VISIBILITY/INVISIBILITY ANALYSIS SYSTEM, LANDSCAPE VISIBILITY/INVISIBILITY ANALYTICAL METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a landscape visibility/invisibility analysis system capable of performing visibility/invisibility analysis of analysis object facilities in an area by taking account of influences such as trees in natural environment.SOLUTION: The landscape visibility/invisibility analysis system according to the present invention includes: a plant community setup section that arranges plant community models in which plant models obtained by modeling types of respective trees comprising respective plant communities, are disposed, at each of areas of the plant communities within a range subjected to the visibility/invisibility analysis of facilities, on a virtual three-dimensional ground surface; and a visibility/invisibility analysis section that performs the visibility/invisibility analysis by erecting an index pole whose height is the height of the facilities, at a position of the facilities to be built on the ground surface and extracting an area of the ground surface to be observed from an observation point of a vertex of the index pole as a visible area.SELECTED DRAWING: Figure 1
