1. An orthoimage creation method comprising:
a coordinate acquisition step of acquiring three-dimensional coordinates for a plurality of feature points;
a photographing step of photographing, by a photographing device, a plurality of photographed images such that each of the plurality of feature points is included in at least two of the photographed images; and
an orthoimage creation step of creating an orthoimage with a ground pixel size of 5 mm or less on the basis of the three-dimensional coordinates of each of the feature points acquired in the coordinate acquisition step, and the plurality of photographed images photographed in the photographing step.
