Abstract

The invention discloses an electronic map display method and device, and belongs to the technical field of electronic maps. The method comprises the following steps: carrying out first merging processing on a plurality of adjacent background surfaces with the same surface type to obtain at least two merged surfaces, or enabling the merged surfaces to comprise an independent background surface; performing second merging processing on the at least two merged surfaces to obtain at least one super surface, wherein each super surface comprises at least two merged surfaces which belong to differentsurface types and have an inclusion relation; and displaying a map user interface including a super surface. According to the invention, different types of merged surfaces with inclusion relations aremerged and then are displayed; the problem that in the prior art, only background faces of the same type and having the adjacency relation are combined into the combined face to be displayed, and consequently effective information displayed on an electronic map is lost is solved. According to the electronic map display method and device, the merged surface with a large area can be displayed, themerged surface with a small area contained in the merging surface with a large area can also be displayed, display of effective information is increased, and electronic map information is displayed more completely.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electronic maps, and in particular, to an electronic map display method and device. Background technique [0002] Electronic maps are maps that are stored and consulted digitally using computer technology. In the process of loading and displaying the data of the electronic map by the electronic device, the map data needs to be loaded from the background server and displayed on the screen of the electronic device. [0003] The electronic map includes map elements such as land, rivers, lakes, and islands. A map element can be represented by a background surface, for example, an island is represented by a background surface; a map element can also be represented by a merged surface composed of multiple background surfaces, for example, a lake is composed of three adjacent background surfaces to represent the merged surface. Among them, a lake is split into three background surfaces b...
