Abstract

A system and method in which position information about a position where material data were created is stored as altitude information of four bytes, longitude information of four bytes and latitude information of four bytes in the Spatial Coordinates area in UMID. Identification information identifies whether the altitude information is, a distance from the center of the earth or a distance from the surface of the earth ellipsoid, measured by a predetermined geodetic coordinate system, using each of values “A” to “F” at one digit in hexadecimal notation, and the distance from the surface of the earth ellipsoid is stated as the altitude information.
