Description

Technical Field

[0001] The present application belongs to the field of geographic information technology, and specifically relates to a map development engine and implementation method for the energy field. Background Art

[0002] Most map functions require secondary development using various SDKs (Software Development Kits), which requires front-end map developers to have a certain understanding of GIS (Geographic Information System) related knowledge, and different front-ends of different projects connect to different map services, so map functions need to be rewritten. Especially if multiple GIS services have been developed or purchased, the development engine tools are different, the geographic data used by each system is stored in a decentralized manner, the acquisition methods are diverse, there are large differences between different SDKs, there is no unified management system, and it is difficult to share and reuse the results and resources between systems. This will require high professional capabilities of front-end map developers and make it difficult to quickly respond to and realize business needs.

[0003] In a unified digital system, most business systems are deployed in the intranet. When secondary development of map functions is carried out in the intranet environment, it is often impossible to connect to the Internet, making it inconvenient to introduce the Internet map SDK, which brings inconvenience to the development of map functions. If existing GIS applications use two types of geographic data, Google open source data and self-surveyed data, the geographic area of ​​​​Google open source data is uncontrollable, and sensitive geographic location information may be inaccurate or changed, which poses certain risks in use. The collection scope of self-surveyed data does not meet national requirements, which poses certain compliance risks. Summary of the invention

[0004] The purpose of this application is to overcome the defects of the existing GIS system development engine tools being different and the difficulty in sharing and reusing the results and resources among the systems.

[0005] In order to achieve the above objectives, the present application proposes a map development engine for the energy field, the development engine comprising:

[0007] Backend services, used to provide map data management, layer configuration, API interfaces and spatial analysis services;

[0008] Data storage, used to store geospatial data.

[0009] As an improvement of the above development engine, the map rendering engine is based on WebGL or other efficient graphics libraries to achieve map rendering and dynamic loading.

[0010] As an improvement of the above development engine, the user interaction module provides map interaction functions, including map zooming, panning, marking points and path planning.

[0011] As an improvement of the above development engine, the visual configuration tool allows users to customize the map style and layout through simple drag and drop and configuration.

[0012] As an improvement of the above development engine, the types of API interfaces include: map foundation, layer service, layer management, spatial analysis service, data visualization, scene special effects, query retrieval and road network planning.

[0013] As an improvement of the above development engine, the map base class API interface is used to create map scenes, realize the loading and visualization of intranet base map data services, and includes map zooming, panning, rotating and clicking functions;

[0014] The layer service API interface is used to support access to data sources in various formats, mashup between graphs and storage of tile map files, and supports spatiotemporal identification of various types of geographic data;

[0015] The layer management API interface is used to add layers according to data files and perform control management including layer visibility function;

[0016] The spatial analysis API interface is used to support business and space-related analysis and assist planning decisions, including buffer analysis, overlay analysis, spatial topology analysis, and terrain analysis;

[0017] The data visualization API interface provides personalized component services and map service publishing functions;

[0018] The scene special effects API interface is used to realize various weather rendering special effects in three-dimensional scenes, as well as particle special effects of fountains and flames;

[0019] The query and retrieval API interface supports POI retrieval, road network retrieval, spatial query, AOI retrieval, coordinate conversion and administrative division boundary query services;

[0020] The road network planning API interface supports the coordinate collection service of specifying the starting and ending point coordinates and the route returned by the passing points, the route planning of adding passing points, and the planning mode selection function.

[0021] As an improvement of the above-mentioned development engine, the API interface encapsulates the native interface of the GIS system, and internally implements the authentication, resource application, resource release and map display functions required for each operation, and only exposes the interface to users to provide input parameters of business data required for the function.

[0022] The present application also provides a method for implementing a map development engine for the energy field. Based on the above development engine implementation, the method includes:

[0023] Step 1: The developer introduces the API interface into the project and performs basic configuration, including setting the map center point and initial zoom level;

[0024] Step 2: Load the map data source through the API interface;

[0025] Step 3: Use the visualization configuration tool to adjust the map's color, label, and icon style;

[0026] Step 4: Add corresponding map interaction functions through the API interface according to business needs;

[0027] Step 5: Publish the map page to the server and perform functional testing and performance optimization.

[0028] Compared with the prior art, the advantages of this application are:

[0029] 1. Realize private deployment of the intranet and reduce dependence on external SDK and data services;

[0030] 2. The API classes, methods, and interfaces are simple and easy to understand, saving developers’ learning costs;
