Abstract

It is an object of the present invention to provide a technique capable of reducing a difference between a three-dimensional shape represented by map data, using approximation, and a real three-dimensional shape. A map data generating apparatus is a map data generating apparatus capable of generating map data representing a three-dimensional shape, using approximation, the map data generating apparatus including: an acquisition part that acquires a shape point sequence indicating the three-dimensional shape, and a control part that generates an arc passing three object points, based on the three object points in the shape point sequence acquired by the acquisition part, and determines whether an approximation division point that should not be approximated in the three-dimensional shape is included in the three object points, based on the arc.
