Provided are a coordinate transformation device, a coordinate transformation program, and a coordinate transformation method which are capable of calculating coordinates on a spheroid at a high speed and with a minimum error. A geographical information management device (100) includes a storage device (2) and a operation unit (3). The storage device (2) stores a basic shape database (D1), an airspace information database (D2), and a parameter information database (D3). The operation unit (3) generates a formula for performing coordinate transformation processing by substituting a transformation parameter included in the parameter information database (D3) into a predetermined formula, transforms information indicating coordinates on a spheroid into coordinates on a true sphere by substituting, into the generated formula, information specifying the shape of the spheroid included in the basic shape database (D1) and information indicating coordinates on the spheroid included in the airspace information database (D2), and outputs the transformed information indicating coordinates on the true sphere. |
