Embodiment Construction

[0048] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0049] Such as figure 1 As shown, the method for displaying points of interest in an electronic map of the present invention includes the following steps:

[0050] Step 11. Obtain a sub-display area in the display area of ​​the electronic map;

[0051] Step 12: Obtain the pre-drawn POI information of the points of interest in the sub-display area under a preset scale, and prioritize the pre-drawn POIs in the sub-display area;

[0052] Step 13: Accumulate the area information of the pre-drawn POI marking outsourcing frame in the order of priority from high to low;

[0053] Step 14: When the ratio of the area information of the first X pre-drawn POI marked outer frames to the area information of the sub-display area is greater than a preset thres...

Abstract

The invention provides a display method and display device of points of interest in an electronic map. The display method comprises following steps: obtaining a sub display zone in the display zone of the electronic map; obtaining points of interest POI information pre-drawn in the sub display zone according to a preset scale; sorting the priorities of the POIs pre-drawn in the sub display zone; successively accumulating the area information of pre-drawn POI label outer packaging frames according to a priority decreasing sequence; when the ratio of the accumulated area information of the former X pre-drawn POI label outer packaging frames and the area information of the sub display region is more than a preset threshold value, drawing the former X-1 pre-drawn POIs in the sub display region, wherein the X is an integer. According to the scheme of the invention, the drawing and updating efficiency of the electronic map can be improved; and the drawing beauty degree of the electronic map is improved.

Description

Technical field [0001] The invention relates to the technical field of electronic map processing, in particular to a method and a display device for displaying points of interest in an electronic map. Background technique [0002] At present, in the drawing process of electronic maps, only the POIs of interest are classified according to the importance level of points of interest, and control whether each type of POI is displayed on the electronic map surface at a certain scale, and the avoidance rules between POIs , It will cause the POI display in some areas to be too dense, making the electronic map graphic information overload, too many text symbols, the display is not beautiful, affecting the browsing of the map, and causing problems such as inconvenient map viewing. Summary of the invention [0003] The purpose of the present invention is to provide a display method and display device for points of interest in an electronic map, which can solve the problem that the POI displ...
