It can generate high-quality two-dimensional maps and three-dimensional scenes in real time, and update the two-dimensional maps and three-dimensional scenes in real time, providing users with intuitive and vivid natural resource data display effects, realizing dynamic data update and information sharing.

[0027] In some embodiments, in step S610, the storage module stores two-dimensional data and three-dimensional data of natural resources and provides a data access interface. The storage module uses Internet of Things technology to collect data on natural resources in real time, including data on geographic location, environmental parameters, and resource utilization status. The data on geographic location, environmental parameters, and resource utilization status can be divided into two-dimensional data and three-dimensional data. Cloud computing technology is used to achieve distributed storage and processing of data, and a data access interface is provided. The two-dimensional data and three-dimensional data can be accessed through the data access interface.

[0028] In some embodiments, in step S620, the service module classifies and processes the two-dimensional data and the three-dimensional data, and provides a service interface. The raster data service unit and the vector data service unit of the service module retrieve and classify the two-dimensional data, obtain raster data and vector data respectively, and provide a raster data service interface and a vector data service interface. The raster data service interface and the vector data service interface are called to call the raster data service interface and the vector data service interface, and the raster data and the vector data are analyzed and distributed. The three-dimensional data is classified through the terrain data service unit, the model data service unit, and the multimedia data service unit of the service module, and terrain data, model data, and multimedia data are obtained respectively. A terrain data service interface, a model data service interface, and a multimedia data service interface are provided. The three-dimensional data is processed through the terrain data service interface, the model data service interface, and the multimedia data service interface, thereby ensuring effective management, processing, and secure access to the data, and also providing necessary support for the execution of business logic.

[0029] In some embodiments, in step S630, the business module integrates the data services of the service module by calling the service interface of the service module, and provides data support for the rendering module. The business layer includes engines that provide various services, including a data processing engine, a service publishing engine, a service calculation engine, a dynamic scheduling engine, a communication interaction engine, and a security control engine. The service units in the service module work closely with the various engines in the business layer to jointly realize the management and application of natural resources. The raster data and vector data in the two-dimensional data are called by the engine in the business layer through the corresponding data services to support business operations such as spatial query, overlay analysis, and buffer analysis. The three-dimensional data is combined with the engine of the business module through the terrain data service unit, the model data service unit, and the multimedia data service unit to realize the construction, roaming, measurement and complex three-dimensional spatial analysis of three-dimensional scenes.

[0030] In some embodiments, in step S640, after the rendering module obtains the efficient data of the business module, it builds a two-dimensional and three-dimensional data model based on the efficient data, and converts the two-dimensional data and the three-dimensional data into a visualization interface based on the two-dimensional and three-dimensional data model; the visualization interface is the visible and interactive part of the user, and the rendering module is the technical core of performing data conversion and graphics drawing. The two are interdependent and together constitute a complete visualization experience. Users can intuitively view and operate two-dimensional and three-dimensional data through the interface. The visualization interface relies on the image output provided by the rendering module to display information, and the rendering module performs corresponding rendering tasks according to the content that needs to be displayed on the interface and the user interaction instructions. The technical implementation of the rendering module determines the performance quality of the visualization interface, such as the clarity, smoothness and realism of the image, which directly affects the user experience. The design of the visualization interface guides how the rendering layer can organize and present data more effectively. The user triggers the recalculation and drawing of the rendering layer through the operation of the visualization interface, and the output of the rendering layer is immediately reflected in the interface, forming a closed-loop interactive feedback system.

[0031] The rendering module involves converting GIS data into final visual effects that can be presented on the platform, involving scene construction, material mapping, lighting and shadows, special effects rendering, interaction, output, etc., which can provide users with intuitive and vivid natural resource information display and decision-making support.

[0032] When it is necessary to display a two-dimensional map, the business module is called based on the two-dimensional and three-dimensional data model, the two-dimensional data is parsed by the business module, and the parsed two-dimensional data is saved in PostgreSQL to obtain a two-dimensional map; the two-dimensional map is published to obtain the OGC map service, and a service access address is generated. Based on the service access address, the two-dimensional data is loaded to the front-end display through OpenLayers to complete the display of the two-dimensional map, that is, the pre-stored two-dimensional data is read according to the business module analysis and saved in the database PostgreSQL. Once the data is saved, the map service will be automatically published, the two-dimensional map will be published as an OGC map service, and a service access address will be generated. OpenLayers will load the two-dimensional data to the front-end display according to the provided service address.

[0033] When it is necessary to display a 3D map, the business module is called based on the 2D and 3D data model, the 3D data is parsed through the business module, and the parsed 3D data is saved in PostgreSQL to obtain the 3D map; the 3D map is published and a service access address is generated. Based on the service access address, the 3D data is rendered to the front end through the 3D data rendering tool to complete the display of the 3D data. Through high compatibility with multiple 3D data formats, a powerful and flexible solution is provided for the management and display of natural resource information. In terms of specific implementation, the rendering module can access multiple mainstream 3D map data formats including 3DTiles, S3M, I3S, and M3D, that is, multiple 3D data rendering tools. Each 3D data rendering tool has its own characteristics, which together support the rich functions and high performance of the platform. 3DTiles: is an open standard developed by Cesium, designed for efficient network transmission and rendering of large-scale 3D geospatial data. 3DTiles supports various types of 3D geometries, such as point clouds, batch 3D models, and architectural models. It can also dynamically load and unload data based on the viewing distance, greatly optimizing the loading speed and browsing experience of large-scale 3D scenes. S3M (SuperMap i3D Tiles Model): is an efficient storage and transmission format for 3D geographic spatial data, especially suitable for fast loading on mobile devices and network environments. S3M uses efficient compression technology and level of detail (LOD) management to achieve fast transmission and smooth browsing of 3D data, and supports lightweight display of large-scale 3D scenes. I3S (Indexed 3D Scene Layer): Applicable to the visualization of large amounts of 3D geospatial data. I3S supports a wide range of 3D feature types, including point clouds, buildings, terrain, etc. Through efficient indexing structure and block strategy, it ensures high-performance rendering of complex 3D scenes on Web and mobile platforms. M3D (Service API for spatial 3D model data): A new data storage format that can cover multiple data types such as aerial, ground, surface, and underground.
