ABSTRACT:
This invention relates to a graphic data processing system, and is more particularly directed to provide an easy-to-operate system and displaying method thereof, for generating scene data from map data and retrieving and displaying attributes containing guide information of ground objects in a scene. In the first place, when a visual point is directed from above to below, a planar map is displayed, and as the visual point shifts in a horizontal direction, a three-dimensional scene image is generated and displayed from a map. Secondly, a three-dimensional window is displayed in a display, and graphic data is displayed inside the window.
