It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] In addition, in order to better illustrate the present invention, numerous specific details are provided in the following specific embodiments. It should be understood by those skilled in the art that the present invention can be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present invention.

[0048] At present, the visualization method of user data of WebGIS geographic information system on the browser side is usually: the browser obtains geographic information on the GIS server through HTTP protocol and displays it as a geographic information layer; obtains user data on the application server and displays it as a business service layer. The defect of this method is that the business data (user data) stored on the application server involves security and leakage risks.

[0049] Based on this, there is a need to provide a WebGIS business data storage method to improve the security of data storage.

[0050] A GIS server is a server used to store, manage, and distribute geographic information data and services. GIS stands for Geographic Information System, which is a technology for organizing and analyzing geographic spatial data. The main functions of a GIS server are to store and manage spatial data and provide mapping and spatial analysis services over the Internet or an intranet.

[0051] GIS servers usually have the following characteristics:

[0052] Data storage: GIS servers can store various types of geospatial data, such as maps, satellite images, spatial vector data, etc. Data can be stored in specific formats, such as geographic databases, file systems, data services, etc.

[0053] Data management: GIS server provides management functions for geographic spatial data, including data organization, retrieval and update. Users can access and operate data through GIS server.

[0054] Data publishing: GIS servers can publish geospatial data to users in different forms, such as Web map services, geoprocessing services, etc. Users can access these services through the Internet or intranet, and use maps, query and analysis tools to operate and analyze spatial data.

[0055] Security: GIS servers usually have security control functions that can control permissions for data and services to ensure that only authorized users can access and use data.

[0056] Scalability: GIS server can be expanded as needed to adapt to GIS applications of different scales and requirements. It can support large-scale data storage and high concurrent access to ensure system performance and stability.

[0057] GIS servers are widely used in various fields, including urban planning, environmental protection, traffic management, agriculture, weather forecasting, etc. Through GIS servers, users can use geographic information data for spatial analysis, decision support, resource management and other tasks.

[0058] Local JS files refer to JavaScript files stored on the local computer. These files are usually independent script files that contain some JavaScript codes to achieve different functions and effects on web pages.

[0059] You can reference local JS files in HTML files by following the steps below:

[0060] Create a .js file on your local computer and write the JavaScript code you want to execute.

[0061] Use in your HTML file section or parts

[0062] <script src＝"yourlocalfile.js">< / script>

[0063] Make sure to set the correct file path. If your .js file is in the same directory as the HTML file, you only need to enter the file name. If the .js file is in a different directory, you need to provide the correct relative or absolute path.

[0064] Save and refresh the HTML file, and the JavaScript code in your local .js file will be executed.

[0065] It should be noted that when using local JS files, make sure that the spelling and capitalization of the file path and file name are correct, otherwise the reference will fail. In addition, you can also use a relative path or an absolute path to reference the JS file, and set it according to the specific file storage location.

[0066] See also Figure 1 , Figure 1 A flowchart of a method for storing WebGIS business data provided in an embodiment of the present application.

[0067] S10, requesting geographic information data from the GIS server, and obtaining corresponding business data from the local JS file.

[0068] In a possible implementation, the requesting the GIS server to obtain geographic information data includes:

[0069] Apply for geographic information service application key from GIS server;

[0070] A local WebGIS application webpage is created using the JS development interface and the application key, and geographic information data is displayed on the WebGIS application webpage.

[0071] In one possible implementation, the geographic information data includes geographic information and map controls; the geographic information includes place names, buildings, terrain, administrative regions and road networks; and the map controls include a scale, a zoom toolbar, an eagle-eye view and distance measurement.

[0072] In this implementation, apply for a geographic information service application key from a third-party geographic information platform, use the JS development interface and application key of the third-party geographic information platform to create a local WebGIS application web page, open the local web page on the browser, and display the geographic information of the third-party platform.

[0073] Furthermore, the geographic information that can be applied to the equipment distribution planning business by the third-party geographic information platform includes: place names, buildings, terrain, administrative regions and road networks; the map controls that can be applied to the equipment distribution planning business include: scale, zoom toolbar, eagle eye view, and distance measurement. When creating a local WebGIS application webpage, write JavaScript code to call the corresponding third-party geographic information platform JS interface and use the geographic information and map controls mentioned above.

[0074] In a possible implementation, the business data is stored in JavaScript data format for invocation by a WebGIS application web page;

[0075] The business data includes the site name, geographical location, device type, device identification and planning description of the device; wherein the site name is recorded in JavaScript string format, the geographical location is recorded in the latitude and longitude format of the GIS server, and the planning description is recorded in JavaScript string format; the data of each device of the same type constitutes a JavaScript array; the device identification is recorded in JavaScript string format, and the content is the identification icon address; various types of device data constitute a JavaScript data group and are assigned to the JavaScript variable InstrumentData.

[0076] In one possible implementation, the business data is displayed in such a way that the WebGIS application webpage references the business data js file. In the WebGIS application webpage display initialization JavaScript code, the business data in the InstrumentData variable is displayed as a device type list, a site distribution layer, and a site details form.

[0077] In this implementation, the business data js file format is as follows:

[0078]

[0079]

[0080] The business data display method is that the WebGIS application web page references the business data js file, and displays the business data in the InstrumentData variable as a device type list, site distribution layer, and site details form in the web page display initialization JavaScript code.

[0081] Furthermore, the device type types array in the InstrumentData variable is displayed as a list of device types. The tname in the types array element is displayed as the type name in the list, and the icon is displayed as the type icon. The stations array in the types array element is displayed as a station distribution map, where each element of the stations array is displayed as a point marker (Maker) of a third-party geographic information platform, the position in the element is converted into the coordinates of the point marker, and the icon in the upper layer is displayed as the icon of the point marker.

[0082] When you click on a point mark, the corresponding site detailed information form is displayed. In the form, the site name is sname, the site location is position, and the planning description is plan.

[0083] Add, delete, and modify business data. To add equipment planning, click on the equipment type list, select the equipment type to be added to the planning site, and then click the mouse on the planning location on the map. The system will then add a blank point mark of the equipment type at the clicked location and display a blank site details form, where the longitude and latitude input boxes have been filled with longitude and latitude coordinate values. After the user enters the complete site information, click the Add button to complete the operation. For deletion and modification operations, the user clicks the Delete or Modify button in the Site Details form after selecting the equipment point mark to complete the operation.

[0084] S20. Based on the geographic information data and the business data, display the user equipment distribution planning geographic information application in the WebGIS application webpage.

[0085] In this implementation, geographic information data and business data are obtained. Use a WebGIS development framework or library, such as Leaflet or OpenLayers, to create a map container for displaying a map. Load the acquired geographic information data into the map. You can use GeoJSON or WMS services to add geographic information data to a map layer. These data can be the location coordinates of a user's device, area boundaries, and so on. According to the needs of the business data, associate the business data with the geographic information data. For example, you can add color identification or other map symbols to devices on the map based on the business data to display the status or properties of the device.

[0086] Add interactive functions based on user needs. For example, you can add interactive functions such as zooming, panning, and clicking on device icons to obtain detailed information to provide a user-friendly map operation and data viewing experience.

[0087] Add other components and controls, such as search boxes, legends, layer switching tools, etc., according to the layout and needs of the map.

[0088] Finally, the WebGIS application web page is deployed on the web server for users to access and use.

[0089] It should be noted that the frameworks and libraries mentioned above are just a few examples. You can choose the appropriate development tools according to your needs. At the same time, for loading and displaying geographic information data, you can also consider using the API of map service providers, such as Google Maps API or Mapbox API.

[0090] S30. Respond to the data saving instruction on the WebGIS application webpage and save the current business data into a local JS file.

[0091] In a possible implementation, the current business data is saved in a local JS file, including:

[0092] If the current business data is newly added business data, it is added and saved in a new local JS file;

[0093] If the current business data is business data modified based on the original business data, it is saved in a local JS file to overwrite the JS file corresponding to the original business data.

[0094] In a possible implementation, the current business data is saved in a local JS file, including:

[0095] Determining the type of browser used by the user through JavaScript code in the WebGIS application webpage;

[0096] If the browser type is Chome or Safari, use the FileReader object to save the business data as a JS file;

[0097] If the browser type is IE, the msSaveOrOpenBlob method of the navigator object is used to save the business data as a JS file.

[0098] In this implementation, first, get the current business data. Use the file operation API in JavaScript, such as the File API or the Blob API, to create a new file object or file stream. Convert the business data into a string format. You can use the JSON.stringify() method to convert the data object into a JSON string. Write the business data string into the newly created file object. Finally, use the local file operation API to save the file object to a local JS file. You can use APIs such as FileWriter or XMLHttpRequest to save the file to a specified location.

[0099] It should be noted that in a browser environment, due to security and privacy restrictions, JavaScript cannot directly save files locally on the client side. The function of saving files locally requires active user operations or the browser's download function.

[0100] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.
