Problems solved by technology

[0004] The embodiment of the present application provides a method and device for displaying map data, which solves the technical problems of historical maps in the prior art. When displaying territory changes, the display content is too single, the display content is not rich enough, and the display effect is not good. When displaying the territorial changes, the display content is rich, so that people can clearly understand the territorial changes of the target regime and the corresponding change events, and display better technical effects

Embodiment 1

[0062] This embodiment provides a method for processing map data, such as figure 1 shown, including:

[0063] Step S101: Obtain historical map data, which includes map data of multiple objects in different historical periods.

[0064] In the specific implementation process, the acquisition of historical map data is used as the material for subsequent editing. Wherein, the multiple objects may refer to different regimes in the historical map. For example, the "Wei", "Shu", and "Wu" regimes in the Three Kingdoms period. In contrast, the map data of an object in different historical periods represents the territory of a regime in different historical periods.

[0065] In the specific implementation process, the historical map data contains multiple map data of different regimes in different historical periods, where different historical periods specifically refer to different historical time periods, and the granularity can be divided into months, years or other intervals.

Embodiment 2

[0097] This embodiment provides a method for displaying map data, which can be applied to the client, such as Figure 5 As shown, the method includes:

[0098] Step S201: Obtain map transition data of the target object.

[0099] In a specific implementation process, the map transition data includes a difference surface and an event mark of a transition event that generates the difference surface, and the difference surface is used to represent changes in the map data of the target object in different historical periods.

[0100] In a specific implementation process, the map transition data may be obtained based on the map data processing method described in Embodiment 1 and then put online. The target object can be any object selected by the user of the historical map. The user in this embodiment generally refers to the user of the historical map.

[0101] Step S202: From the map transition data, extract the difference surface and the event mark of the transition event that...

Embodiment approach

[0115] In one embodiment, the specific implementation process of each map graphics change process can be: [Example 1], such as Image 6 Shown:

[0116] First of all, it is necessary to display the map window of the map area adapted to the main regime, and display the blank base map of the earth on the map window.

[0117] Next, perform step 1d: display the map before the change. Specifically, the displayed map before the change includes the map graphic of the main regime and the first related map graphic. Here, the first related map graphic is a map graphic of a regime other than the main regime. For example, the first related map graphic can be It is the territory of other regimes except the main regime in all regimes. Different states can be used to distinguish and display the territory of the sovereign regime and the territories of other regimes before the change on the blank base map of the earth.

[0118] Step 2d: Display difference surface 1 and event marker 1. Speci...

Abstract

The invention discloses a map data display method. The method comprises the following steps: acquiring map transition data of a target object; extracting a difference surface and an event mark from the map transition data; and displaying the map graph change of the target object and a change event generating the map graph change based on the difference surface and the event mark. According to the invention, the technical effects that the display content is rich when the change in an area is displayed, people can clearly know the change condition of the area of the target political right and a corresponding change event, and the display effect is better are achieved. Meanwhile, the invention further discloses a map data display device and a storage medium.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for displaying map data. Background technique [0002] In the long river of history, many regimes have emerged in the land where people live, and their territories are changing from birth to demise. In the process of learning history, people must understand the history of the rise and fall of each regime, as well as the changes in the territory. [0003] Historical maps are different from ordinary electronic maps. They are mainly used to display the territorial changes of various regimes in various historical periods, and are an important tool for people to understand historical changes. However, when the existing historical maps show the changes in the territory, the displayed content is too single, the displayed content is not rich enough, and the display effect is not good. People cannot clearly understand the situation of the regime's territoria...
