Abstract
In a system for displaying map information, an object base storage unit stores an object base relating to relational objects, a map data base storage unit stores a map data base relating to figure elements of map data, and an attribute data base storage unit stores an attribute data base relating to attribute data related to the figure elements of the map data. In response to an input command, a head one of the relational objects is retrieved from the object base, and entity objects are desired from a head relational object by referring to the object base, so that each of the desired entity objects is processed. The map data retrieving section retrieves the map data from the map data base in response to the processing of each map data entity object of the derived entity objects, and the attribute data retrieving section retrieves the attribute data from the attribute data base in response to the execution of each of attribute data entity objects of the derived entity objects. The converting section converts the map data and attribute data into three-dimensional display data and the display data is three-dimensionally displayed on the display unit. In this case, predetermined height…
