Map labeling method and device

Abstract

The invention discloses a map labeling method and device, and belongs to the field of information processing. The method comprises: receiving a map and a to-be-labeled identifier, determining a targetrectangle in a to-be-labeled polygon area on the map, wherein the area of the target rectangle is in positive correlation with the area of a maximum inscribed rectangle of the polygon area; Determining the size of an identifier corresponding to the polygonal area according to the size of the target rectangle, and enabling the target rectangle to be a minimum bounding rectangle of the identifier;And displaying the map, and displaying the identifier in the polygonal area to be labeled on the map. According to the method, the target rectangle is used as the outer wrapping rectangle to mark theidentifier, it can be guaranteed that the size of the identifier marked and displayed in the polygonal area is matched with the area of the polygonal area, user identification is facilitated, and theflexibility and the marking effect of marking are effectively improved.

Description

technical field [0001] The present application relates to the field of information processing, and in particular to a map labeling method and device. Background technique [0002] Map labeling refers to marking labels (such as text or graphics, etc.) on the map for various map elements (such as urban areas, roads, and rivers, etc.). [0003] In related technologies, the map server divides the polygonal area occupied by each map element on the map according to a preset area division algorithm. When receiving the map acquisition request of the specified area sent by the map client, the map server may send the map of the specified area that has been divided into map elements and the identifier corresponding to each map element to the map client. The map client can use the skeleton line method to determine the skeleton line of the polygonal area occupied by each map element on the map, and then mark a fixed-size mark at the midpoint of the skeleton line. [0004] However, in t...
