[0077]

[0078] By displaying the corresponding relationship between the spatial data information of POI and the bitmap file on the navigation electronic map, the POI schematic diagram can be obtained, and the user can clearly obtain the position of each entrance of POI and the positional relationship between each other through the POI schematic diagram. When the user selects a travel destination through POI retrieval, the location indication icon will give a clear location indication on the navigation electronic map.

[0079] Two, the road

[0080] A road is composed of a series of connected spatial longitude and latitude coordinate pairs, and is an important element used to describe the topological relationship of roads, such as Fourth Ring East Road, Xueyuan Road, etc.

[0081] First, the corresponding relationship between the spatial data information of the road and the bitmap file is established through the dynamic coordinate mapping metho...

Abstract

The invention provides a method and a device for displaying a navigation electronic map, and belongs to the field of electronic map displaying. The method comprises the following steps of: obtaining space data information of a navigation target, wherein the space data information contains the longitude and latitude coordinates of the navigation target; obtaining a bitmap file corresponding to the navigation target according to the space data information of the navigation target; and displaying the bitmap file on the current navigation electronic map, and displaying the space data information of the navigation target in the position corresponding to the navigation target on the bitmap file. According to the technical scheme, the space data information can be effectively correlated with the bitmap file.

Description

technical field [0001] The invention relates to the field of electronic map display, in particular to a method and device for displaying a navigation electronic map. Background technique [0002] Under normal circumstances, the navigation electronic map adopts the digital line drawing method, that is, the vector elements such as points, lines, and planes composed of a single or a series of connected spatial coordinate pairs are used to express the road network structure and various navigation elements, such as road lines , administrative division, POI (Point of Interest, point of interest), etc. This method can accurately express the spatial position of navigation elements and the spatial relationship between navigation elements, which is convenient for high-precision mapping and spatial relationship calculation, but there are problems such as abstract information expression, not intuitive enough, and difficult to understand. [0003] As a supplement to the digital line dra...
