1. A station installation support method comprising:
a vertical direction visibility detection subject building selecting step for setting, on two-dimensional map data indicating buildings serving as candidates for installing terminal station devices, locations of base station installation structures serving as candidates for installing base station devices as base station candidate locations, and selecting, for each of the base station candidate locations, buildings that have other buildings between themselves and the base station candidate location as visibility detection subject buildings;
a vertical direction visibility detection processing step for setting the heights of the buildings at an identical length, setting a higher position than the buildings as an installation altitude of the base station devices, and detecting, for each of the visibility detection subject buildings selected in the vertical direction visibility detection subject building selecting step, a visibility range of the visibility detection subject building from the installation altitude of the base station device in the base station candidate location; and
a point cloud data processing step for narrowing down, on the basis of the detected visibility ranges, three-dimensional point cloud data acquired by photographing a region including the base station installation structures and the buildings, and using the narrowed-down point cloud data to determine the visibility of the buildings from the base station candidate locations.
