ABSTRACT:
A terminal apparatus of the present invention having a position detection unit and a display unit further includes a geographic information storage unit for storing three-dimensional terrain shape information, an attitude detection unit for detecting the attitude of the terminal apparatus, and an image creation unit for obtaining information on a vector vertical to the display unit based on information on the attitude obtained by the attitude detection unit and creating a three-dimensional terrain image at a viewpoint using a current position obtained by the position detection unit, information on a line-of-sight defined by the information on the vector, and the three-dimensional terrain shape information in the geographic information storage unit. When the attitude of the terminal apparatus is changed, the three-dimensional terrain image on the display unit is updated, following a change in the attitude of the terminal apparatus.
