PURPOSE: A method for expressing dynamically map data is provided to show vivid images to a user by applying dynamical expressions to map data. CONSTITUTION: A code of display datum is searched.(S310) A corresponding line is extracted if the display datum is a road(S312). The kind of the road is determined(S314). Vehicles passes on the road if the kind of the road is an expressway such as an express way or a highway, and a tunnel(S318). A train or a subway train pass on a railway or a subway if the kind of the road is the railway or the subway(S322,s324,s326). Smoke is displayed by extracting a location coordinates if the display datum is a factory or a chimney(S332,s334). A corresponding area is calculated and various animals are displayed on the corresponding region if the display datum is a mountain or a green tract of land(s342,s344,s346). An area and a coordinates of a corresponding hydrosphere are calculated if the display datum is a hydrosphere(S352,s354). An animation is executed on the corresponding hydrosphere by determining whether the corresponding hydrosphere is a river or a sea(s355-s359). |
