Abstract: A vector map display method executed by a user terminal device may include: a web vector map display viewpoint change step of changing a viewpoint of a web vector map according to the directions of previously stored first and second viewpoints; a background or POI information extraction step of extracting a background or one or more pieces of POI information corresponding to a current position of the user terminal device from data of the web vector map by reflecting the first and second viewpoints; a size ratio adjusting step of adjusting the size ratio of the extracted background or POI information; a current web vector map data generation step of generating data of the current web vector map corresponding to the current position; and a current web vector map display step of displaying the data of the current web vector map.

Abstract: A graphics-based web vector map display method may include: extracting object information from map sheet information of a previously stored original vector map; extracting an input array of a display engine for each type of the original vector map; storing the object information in the extracted input array of the display engine; separating the input array having the object information stored therein into property layer arrays according to property information of map information; storing the separated property layer arrays as map sheet information of a web-based vector map; and generating service-specific vector map information from the map sheet file of the web-based vector map.
