[0001] The present application relates to the field of spatial information service technology, and in particular to a planning spatial information service platform based on GIS. Background Art

[0002] The Spatial Information Service Platform refers to: using the "Digital Earth" theory, based on key technologies such as remote sensing, GIS, virtual simulation, network, database and multimedia, to deeply develop and utilize spatial information, and build information infrastructure and information systems that serve urban planning, construction, and management; serve the government, enterprises, and the public; and serve the sustainable development of population, resources, environment, economy and society.

[0003] A Geographic Information System (GIS) is a computer system that, powered by computer hardware and software, collects, manages, analyzes, and displays geographic attribute data about objects or phenomena on the Earth's surface. GIS software provides specialized network analysis modules for analyzing transportation networks, facility networks, and other network components. Network analysis requires comprehensive information or data, including spatial data, attribute data, and topological relationships, to analyze and calculate the overall spatial, quantitative, and qualitative characteristics of the network, meeting the needs of specialized research and analysis such as resource allocation, facility site selection, and optimal path analysis.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the current spatial information service platforms are mostly focused on simple information services such as population information, administrative information, and traffic information, and are relatively lacking in deep data information service content.

[0039] User Login Module 1 needs to implement user login. Its presentation layer displays the login interface and retrieves the user's login information. This information is then transmitted to the business layer via the middle layer. The business layer then requests the persistence layer, receives the login result, and returns it to the presentation layer. The persistence layer of User Login Module 1 takes a String username and password as input and returns the login information using a post request.

[0040] The presentation layer of Data Monitoring Module 2 is used to display basic spatial information on a map and obtain user query information. Specifically, in this embodiment, basic spatial information includes six dimensions: space, services, population, transportation, industry, and resources and environment. The main interface of Data Monitoring Module 2 is primarily a map, and the map functionality is implemented using the GMap product. GMap is implemented by configuring and generating a map application in GInfoShare, and embedding the application address into the system page via an iframe on the front end. Basic spatial information is displayed and hidden using a layer control tree. Query information is transmitted to the business layer, where queries and statistics are performed. The query function draws a range on the map to retrieve and display the relevant facilities and their statistics, as well as the basic spatial information. Queries are implemented using spatial queries using the GIS service layer service REST interface. Statistics are obtained by calling external GIS interfaces. The statistical function performs various statistical methods on a single layer and is divided into three parts: filtering, statistics, and multi-layer statistics. The filtering function performs SQL-based queries on the selected layer and displays the query results on the map. b. Statistics are available in two modes: Single-field statistics (sum, count, minimum, etc.) are performed on all values ​​in a field of the selected layer based on the field type; Grouped statistics require a character field (grouping field) and a numeric field (statistics field). The character field values ​​are first grouped, and then the numeric field is statistically analyzed (sum, average, maximum, minimum, standard deviation, variance, etc.) based on the grouped values. Statistical results are presented in both table and chart formats. c. Multi-layer statistics uses the selected layer as the base data, adding other data layers under the same administrative division. After selecting fields, statistical calculations are performed by entering function expressions.

[0041] The GIS map service released by the data monitoring module 2 is displayed on the interface, which can establish visual layers through six dimensions: space, service, population, transportation, industry, and resources and environment; it can dynamically query the population, enterprises, area, and facilities in the manually selected area; it can perform statistical analysis on the selected area; it can select different forms of base maps; it can clear operations on the page; and it can have common operating tools for base maps.

In this embodiment, the population analysis model is further divided into population distribution quantity, population distribution profile, employment and residence distribution network, residential population work location, and working population residence location. User operation information is transmitted to the business layer through the mid-level layer. The business layer includes planning model invocation, planning model attachment upload, file information query, file deletion, and file download. Specifically, planning model invocation inputs parameters and returns a JSON call result; planning model attachment upload inputs a planning model file of type MultipartFile and returns the uploaded file information of type FileEntity; file information query inputs an attachment ID of type String and returns file information of type FileEntity; file deletion inputs a plot primary key of type String and returns no data; file download inputs a String data type and the corresponding file suffix and file type and returns a file stream of the file to be downloaded.

The NA Server interface receives parameters such as point coordinates and time and returns reachability area and route graphics. After receiving the reachability range, the 15-minute Living Circle function uses spatial queries to query selected facilities and services for statistical purposes.
