Map generating system and map management system

A map generation system, comprising:

• a recording means for recording map data, and facility management information of facilities in the map data;
• a means for displaying on a display means said map data that displays at least one of the facilities;
• a means for displaying distance information from an origin to a starting point and to an end point of said facility and an attribute information of the facility;
• a means for receiving input for changing at least any one of said displayed distance information or said attribute information;
• and
• a means for redisplaying on said display means the facility based on said input for changing by generating on said map data.

A map generation system comprising:

• providing a system connected to a recording means for recording map data having a skeletal graphics of facilities, said system being connected to facility management data that coordinates an origin coordinate with a distance from the origin coordinate to a starting point and to an end point of a graphical figure of a facility;
• providing a search means for searching for a position corresponding to said origin coordinate from within said map data;
• providing a means for determining a proper generation range of said facility graphical figure by using said skeletal graphics;
• providing a means for generating said facility graphical figure by means of a facility graphical figure generation program by using facility parameters stored in said facility management data;
• and
• providing a display means for displaying a generated graphical figure of said facilities on a map generated from said map data.

A map generating and graphical display system for use with a geographic information system (GIS) for mapping data from a map database and a distance based facility parameters database comprising:

• a map data search unit;
• a facility parameters database search unit;
• a graphics generation information search unit for retrieving facility parameters including a base coordinate from the facility parameters database search unit and for placing the base coordinate onto skeletal graphics from the map database;
• a skeletal graphics search and trace unit for tracing on a map retrieved from the map database via the map data search unit, and for finding skeletal graphics of at least one facility on the map selected from the map database wherein the skeletal graphics are included on the map and are then traced upon from the base coordinate to include a starting point and an ending point which are stored;
• a graphical figure generation function library searchable by a graphical figure generation function search unit using a graphical figure generation number from the facility parameters database and which is connected to the graphics generation information search unit;
• a graphics generation dimension selector unit for searching for dimension parameters of the facilities listed in the facility parameters database and connected to the skeletal graphics search and trace unit;
• and
• a three dimensional graphics generation unit for generating a 3D graphical representation of the facility on the map to be stored and displayed.
