The invention discloses an information display control method and device for an electronic map. The method includes the steps that the current coordinates, on the electronic map, of a mobile terminal are determined, and the current orientation information of the mobile terminal is determined; with the current coordinates of the mobile terminal as a datum point, place coordinates, located within the range of specific distance around the datum point and the range of the current orientation, OF a place point of interest (POI) is searched for; a real-scene picture corresponding to the current coordinates and the orientation range of the mobile terminal is displayed, and the mark of the found POI is displayed on the real-scene picture; after the mark of the POI is triggered, a place detail interface corresponding to the POI is displayed. By the utilization of the information display control method and device, the efficiency for searching for a target place can be improved, man-machine interaction operation is reduced, and the occupied machine resources are reduced.
Description
technical field [0001] The present invention relates to the technical field of electronic maps, in particular to an electronic map information display control method and device. Background technique [0002] An electronic map is a digital electronic map, which is an electronic map that is stored and consulted digitally using computer technology. The electronic map can easily combine and splice elements in any form on the content of the ordinary electronic map to form a new electronic map. The method of storing information in electronic maps generally uses vector image storage. The scale of electronic maps can be enlarged, reduced or rotated without affecting the display effect. Current electronic map systems generally use geographic information systems to store and transmit electronic map data. [0003] In the current technical solution of the electronic map system, there is also a street view (Street View) display technology. Street view display technology is a real-scene...
