When application requirements change, developers must modify the code, resulting in high labor costs and low maintenance efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a GIS map interaction method and system, which solves the technical problem that existing technologies, which implement complex GIS map interactions through customized development, require code modification when application requirements change, resulting in high labor costs and low maintenance efficiency.

[0007] The layer click events of the instantiated GIS map component are associated with the first action sequence to form the first interaction logic;

[0008] The button click event of the instantiated button component is associated with the second action sequence to form the second interaction logic, and the GIS map interaction is completed based on the first interaction logic and the second interaction logic.

[0009] Furthermore, the first basic attribute includes basic map attributes and business surface layers, and the step of configuring the first basic attribute of the GIS map component includes:

[0010] Enter the administrative division code in the initial mask area to obtain the display range, enter the longitude and latitude coordinates in the display range to determine the center point, and set the zoom level for the display range to complete the basic map attribute configuration;

[0011] Associating the data source with the display area allows for color mapping of the display area based on the data source, thus completing the business plane layer configuration.

[0012] Furthermore, the data source is GDP data, and the step of color mapping the display range based on the data source specifically includes:

[0013] The GDP data is compared with a data threshold. If the GDP data is greater than the data threshold, the display area is assigned a first color. If the GDP data is less than the data threshold, the display area is assigned a second color.

[0014] Furthermore, the second basic attribute includes appearance attributes and display attributes, and the step of configuring the second basic attribute of the button component includes:

[0015] Set the button background color, button display text, text color, text size, and button border style to complete the appearance attribute configuration;

[0016] Set the button component to a hidden state to complete the configuration of the display attributes.

[0017] Furthermore, the first action sequence includes a drill-down administrative division mask action, a first layer loading action, and a button component display action, while the second action sequence includes a return to the administrative division mask action.

[0018] Furthermore, after the step of associating the layer click events of the instantiated GIS map component with the first action sequence to form the first interaction logic, the method further includes:

[0020] Furthermore, the second action sequence also includes a second layer loading action.

Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] Please see Figure 1 The first embodiment of the present invention provides a GIS map interaction method, which includes the following steps:

[0036] S10: Construct GIS map components and button components to form a visualization component library. The GIS map components include layer click events, and the button components include button click events.

[0037] By constructing the GIS map component and the button component, graphical configuration data can be achieved, enabling visualization of application scenarios. By setting the layer click event and the button click event, it can be clearly defined that when the GIS map component and the button component are clicked, corresponding actions must be triggered to complete the map interaction.

[0038] S20: Instantiate the GIS map component and the button component in the graphical design area to configure the first basic property of the GIS map component and the second basic property of the button component;

[0039] In this embodiment, the first basic attribute includes map basic attributes and business surface layers, and the second basic attribute includes appearance attributes and display attributes. The first basic attribute and the second basic attribute are the basic parameters of the GIS map component and the button component, respectively. Understandably, the GIS map component and the button component are typically instantiated in the graphical design area of ​​a web application interface through a component library panel or toolbox.

[0040] Specifically, step S20 includes:

[0041] S210: Input the administrative division code in the initial mask area to obtain the display range, input the longitude and latitude coordinates in the display range to determine the center point, and set the zoom level for the display range to complete the basic map attribute configuration;

[0042] Select the GIS map component from the component library, move it to the main design canvas area, and then obtain the initial mask area in its properties panel. By setting the longitude coordinates, the latitude coordinates, and the zoom level, you can ensure that the display area is always centered.

[0043] S220: Associate the data source with the display area to perform color mapping on the display area according to the data source, so as to complete the business plane layer configuration;

[0044] In this embodiment, the data source is GDP data. In some embodiments, the data source is population data. Understandably, different databases can be accessed to obtain different types of data sources depending on different needs. Further, the GDP data is compared with a data threshold. If the GDP data is greater than the data threshold, a first color is assigned to the display area; if the GDP data is less than the data threshold, a second color is assigned to the display area. If the data threshold is 50,000, when the GDP data is greater than 50,000, the display area is filled with dark blue; when the GDP data is less than 50,000, the display area is filled with light blue.

[0045] S230: Set the button background color, button display text, text color, text size, and button border style to complete the appearance attribute configuration;

[0046] S240: Set the button component to a hidden state to complete the configuration of the display attributes;

[0047] Understandably, once the GIS map component is initially loaded, the button component is invisible, and whether it is displayed is controlled according to the subsequent linkage rules.

[0048] S30: Associate the layer click events of the instantiated GIS map component with the first action sequence to form the first interaction logic;

[0049] The first action sequence includes drilling down the administrative division mask, loading the first layer, and displaying the button component.

[0050] Understandably, when a user triggers a layer click event on the GIS map component, the GIS map component automatically performs a map drill-down operation, displays the first layer after drill-down, and shows the button component. To improve user interaction efficiency, the method further includes:

[0051] S50: Configure an execution condition template for the first interaction logic. When the user fills in the execution parameters in the execution condition template, set an execution threshold for the first interaction logic based on the execution parameters and the first basic attribute.

[0052] By setting the execution condition template, users can customize whether or not to drill down on the map. Taking GDP data as the data source in the first basic attribute as an example, if the user sets the GDP drill-down threshold to 80,000 in the execution condition template, when the user triggers a layer click event of a certain GIS map component, the system will automatically compare the GDP drill-down threshold with the first basic attribute in the current GIS map component. If the GDP data in the first basic attribute of the current GIS map component is greater than 80,000, the first interaction logic will be executed to display the map in drill-down mode. If it is less than 80,000, the first interaction logic will be stopped.

[0053] S40: Associate the button click event of the instantiated button component with the second action sequence to form the second interaction logic, and complete the GIS map interaction based on the first interaction logic and the second interaction logic;

[0054] The second action sequence includes a return to the administrative division mask action. Understandably, after the map is drilled down, the button component is displayed. By triggering the button click event, a return operation can be performed, returning from the drilled-down layer to the display area. Preferably, the second action sequence also includes a second layer loading action, that is, after returning to the display area, the corresponding layer of the display area is loaded to avoid the layer remaining on the drilled-down layer or display errors.

[0055] By constructing the GIS map component and the button component, common functions are encapsulated into prefabricated modules. The configuration of the first and second basic attributes of the GIS map component and the button component replaces the traditional code-based configuration method. The layer click event and the button click event are respectively associated with the first action sequence and the second action sequence, replacing the writing of complex condition judgments and function call logic. When maintenance is required, the attributes of the GIS map component and the button component and their association with the action sequence can be modified directly on the graphical interface, reducing labor costs and improving maintenance efficiency.
