CONSTITUTION: A parameter converting apparatus includes an initial ground control point input unit(100), a coordinate conversion improvement unit(210), a geometrical image correction unit(220), an automatic ground control point matching unit(230), and an error range checking unit(240). The initial ground control point input unit manually inputs at least predetermined number of initial ground control points and automatically matches remaining initial ground control points. The coordinate conversion improvement unit improves accuracy in coordinate conversion. The geometrical image correction unit applies the improved coordinate conversion information to an image to be corrected to generate a geometrically corrected image. The automatic ground control point matching unit automatically matches ground control points with coordinate conversion information obtained through repeated parameter conversion using the geometrically corrected image and previously stored ground control points. The error range checking unit checks if root mean square error of the coordinate conversion information is in a predetermined range or not.
