Preferably, the present invention can use a sphere to have a correct global geospatial relationship, and use a Geographic Information System (GIS) to draw and mark geographic network lines, sea and land shapes, human geography, and important world heritage, etc., to make a global entity Models, better, users can edit the data content of different layers according to the purpose of use. For example, in the geographic information, according to the characteristics of the layer data, they can be created as "point feature layer", "line feature layer" and "surface map". "Layers"; data features are point information such as city information, world heritage information, and important location information, etc., are marked as points in the map layer and a simple name is identified next to the point. When detailed information about the point map layer is required to be displayed , Click the point to display the detailed text box, and you can edit the text; the data features are line-type information such as important river lines, railroad transportation routes, and other line-type maps. If they are displayed at the same time, it will prevent the screen from staggering too many lines. Read recognition, so it can be created as a line feature layer in a map layer To establish a check function, you can select it when you need to display the line of the line feature layer; the data characteristics are area information such as national coverage, important lake coverage, large national park coverage, and important city size coverage. Area information with range, if displayed at the same time, it will complicate screen block color blocks and hinder reading recognition. It can be established as a selective surface feature layer.

The above method can create geographic information and edit layer data according to user needs; more preferably, users can also directly link existing geographic information, such as Global Numerical Elevation Model (DEM), Google Earth (Google Earth Earth).

Then, step S02 is performed to select a display layer; the layer to be displayed is selected from the geographical information created above or from the existing geographical information, and the selected layer is displayed in a spherical shape on a screen.

Then proceed to step S03 to edit and display the layers; when the information of the different layers selected interfere with each other, for example, they overlap with each other, the layout position interferes with each other, the text boxes overlap or the number of text characters, and the font size needs to be adjusted, in this step you can Make edits, skip this step if you don't need to edit.
