[0002] The standard of OGC (Open Geospatial Consortium) services defines a series of interfaces and protocols, such as WMS (Web Map Service), WFS (Web Feature Service), and WCS (Web Coverage Service), etc. These standards enable seamless sharing and integration of geospatial data between different GIS (Geographic Information System) software.

[0003] The desktop geographic information system is a desktop application form in GIS software, which integrates spatial graphics processing, relational database management, statistical graphics display, spatial analysis functions, network communication capabilities, and object-oriented programming techniques. This desktop geographic information system provides users with convenient and powerful geographic information processing capabilities through an intuitive graphical user interface (GUI).

[0032] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0033] Embodiment 1

[0034] The method for publishing OGC services based on a desktop geographic information system provided in the embodiments of this application can be applied to an application environment as Figure 1 shown. Among them, the terminal communicates with the server through a network. The data storage system can store the data that the server needs to process. The data storage system can be set separately, integrated on the server, placed in the cloud or on other servers. The terminal can send a to-be-processed OGC service publishing request to the server. After receiving the to-be-processed OGC service publishing request, for the to-be-processed OGC service publishing request, the server slices the geological map to obtain slice files, and records the zoom levels and row-column numbers corresponding to the slice files; uses a simple feature model data processing tool to process the slice files to generate database operation commands, and the database operation commands include the binary code stream obtained by converting the slice files; according to the format of the ubiquitous geoscience big data storage model, create forests, trees, and branches according to user needs, calculate the coordinate range of the slice files according to the zoom levels and row-column numbers corresponding to the slice files, extract the binary code stream corresponding to the slice files from the database operation commands, and store the binary code stream and the coordinate range in the leaves to store the slice files in the ubiquitous geoscience big data storage model database; generate an OGC service access address according to the storage location of the slice files in the ubiquitous geoscience big data storage model database to complete the OGC service publishing by using an open-source desktop geographic information system. The server can feedback the obtained OGC service access address for the OGC service publishing request to the terminal.

[0035] In addition, in some embodiments, the OGC service publishing method based on the desktop geographic information system can also be implemented separately by a server or a terminal. For example, the terminal can directly process the OGC service publishing request to be processed, or the server can obtain the OGC service publishing request to be processed from the data storage system and process the OGC service publishing request to be processed.

[0036] Among them, the terminal can be, but is not limited to, various desktop computers, laptop computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc., and the portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server can be implemented by an independent server or a server cluster composed of multiple servers, and can also be a cloud server.

[0037] In an exemplary embodiment, as Figure 2 shown, an OGC service publishing method based on the desktop geographic information system is provided. This method is executed by a computer device, and can specifically be executed separately by a computer device such as a terminal or a server, or can be jointly executed by a terminal and a server. In the embodiments of the present application, taking this method applied to Figure 1 the server as an example for illustration, the method includes the following steps.

[0038] Step S1: Slice the geological map to obtain slice files, and record the zoom level and row and column numbers corresponding to the slice files.

[0039] Step S2: Use a simple feature model data processing tool to process the slice files to generate database operation commands; the database operation commands include the binary code stream obtained by converting the slice files.

[0040] Step S3: According to the format of the ubiquitous geoscience big data storage model, create forests, trees, and branches according to user needs, calculate the coordinate range of the slice files according to the zoom level and row and column numbers corresponding to the slice files, extract the binary code stream corresponding to the slice files from the database operation commands, and store the binary code stream and the coordinate range in the leaves to store the slice files in the ubiquitous geoscience big data storage model database; wherein, the forest includes the trees, the trees include the branches, and the branches include the leaves; the ubiquitous geoscience big data storage model database adopts the ubiquitous geoscience big data storage model.

[0041] Step S4: Generate an OGC service access address according to the storage location of the slice files in the ubiquitous geoscience big data storage model database to complete the OGC service publishing using an open-source desktop geographic information system.

[0042] Implementing the above steps S1 to S4, in this embodiment, an open-source desktop geographic information system is used to slice geological maps to obtain slice files, and the corresponding zoom levels and row-column numbers of the slice files are recorded. The slice files are converted into binary code streams by using a simple feature model data processing tool. According to the format of the ubiquitous geoscience big data storage model, forests, trees, and branches are created according to user requirements, and the coordinate ranges of the slice files are calculated based on the corresponding zoom levels and row-column numbers of the slice files. The binary code streams and coordinate ranges are stored in the leaves to store the slice files in the ubiquitous geoscience big data storage model database. According to the storage locations of the slice files in the ubiquitous geoscience big data storage model database, OGC service access addresses are generated to complete the OGC service publishing by using the open-source desktop geographic information system. Thus, the open-source desktop geographic information system can have the OGC service publishing function, and the ubiquitous geoscience big data storage model is introduced in the OGC service publishing process, which can provide a high-performance OGC service with a millisecond-level response for tens of billions of data. Therefore, compared with the OGC service publishing process of existing commercial geographic information systems, the OGC service publishing process of this embodiment is simple, takes less time to publish, and has high publishing efficiency.

[0043] Since the model used in the OGC service publishing process of existing commercial geographic information systems has low efficiency, resulting in a complex publishing process, long publishing time, and low publishing efficiency, this application introduces a highly efficient ubiquitous geoscience big data storage model. Also, considering the lack of tools for directly converting slice files into the required format of the ubiquitous geoscience big data storage model, this application further introduces a simple feature model. First, the existing simple feature model data processing tool is used to convert the slice files into binary code streams, and then the binary code streams are converted into the required format of the ubiquitous geoscience big data storage model, so that the conversion process can be completed by using existing tools, greatly reducing the development complexity.

[0044] The interoperability between the simple feature model and the ubiquitous geoscience big data storage model is driven as follows: The simple feature model is a conceptual model based on the abstraction of structured data. The geometric information and attribute information of each feature are completely stored in a record, which has the advantages of simple data structure, stability, scalability, and strong interoperability. Currently, mainstream geographic information systems all adopt the simple feature model to store geospatial data. The ubiquitous geoscience big data storage model (GeositeServer) is different from traditional relational spatial databases. It takes the natural tree growth law as the generalization abstraction model and abstracts data into four structures: forest, tree, branch, and leaf to provide high-performance OGC services with millisecond-level response for tens of billions of data. The difference in data storage models causes other software to be unable to directly read the data stored in the ubiquitous geoscience big data storage model database, forming a data exchange barrier. Data exchange relies on external data formats such as shapefile and Geojson, which limits the popularization and application of the high-performance OGC services of the ubiquitous geoscience big data storage model. This embodiment designs a data format interoperability drive, which realizes the two-way mapping drive between the ubiquitous geoscience big data storage model and the simple feature model at the database level, achieving seamless conversion of data formats at the database level without relying on external data formats or middleware assistance, completely eliminating the technical barriers existing in the data exchange process, and realizing the efficient interconnection, interoperability, and interaction between the data of the ubiquitous geoscience big data storage model and the simple feature model data.

[0045] Based on this, this embodiment provides an OGC service publishing method based on an open-source desktop geographic information system. The OGC service publishing process is as follows:

[0046] (1) Geological map production

[0047] Use the open-source desktop geographic information system to draw a map, add details such as stratigraphic stripes, borehole positions, and terrain changes on the map, set colors, symbols, and line types to represent different geological bodies, and add legends, labels, etc.

[0048] At this time, in this embodiment, before slicing the geological map to obtain slice files, the OGC service publishing method based on the desktop geographic information system in this embodiment further includes: producing a geological map, specifically including: drawing a map, adding stratigraphic stripes, borehole positions, and terrain changes on the map, setting colors, symbols, and line types on the map to represent different geological bodies, and adding legends and labels on the map to produce the geological map.

[0049] (2) Geological map slicing

[0050] The slicing of geological maps is to pre - cut geological maps into small pictures according to different scales and regions and save them on the server. When a user accesses a geological map, the slices of the required area can be directly returned without generating the entire geological map in real - time, thus greatly shortening the loading time. The slicing process is an existing process. This slicing process requires setting slicing parameters, such as the resolution of the slice, the zoom level, the slicing direction, etc. Since it is possible to select a partial area of the geological map for slicing, after selecting the slicing area, the slicing operation is performed based on the slicing parameters.

[0051] In this embodiment, the slicing process can be as follows: When the geological map is sliced for the first time, the geological map is evenly divided into two slices. At this time, the zoom level is 1. When the geological map is sliced for the second time, the two slices obtained from the first slicing are each evenly divided into four slices, resulting in 8 slices. At this time, the zoom level is 2, and so on. After the slicing is completed, the row and column numbers to which the slices belong are recorded. For example, among the two slices obtained from the first slicing, the row and column numbers of the left slice are (0, 0), and the row and column numbers of the right slice are (0, 1).

[0052] At this time, in this embodiment, the geological map is sliced to obtain slice files, and the zoom level and row and column numbers corresponding to the slice files are recorded.

[0053] Among them, slicing the geological map to obtain slice files specifically includes: presetting slicing parameters and slicing the geological map based on the slicing parameters to obtain slice files. The slicing parameters include resolution, zoom level, and slicing direction.

[0054] (3) Processing of slice files

[0055] After reading each slice file obtained, the slice file at this time is a raster file. Using a simple feature model data processing tool, the spatial reference system information of the slice file (used to determine the coordinates of each position point in the slice file), the zoom level, the row and column numbers, and the content of the slice file are converted into a binary code stream, and corresponding SQL statements (i.e., database operation commands) are generated. This database operation command is used to create a table, insert data (i.e., insert the binary code stream into the table), and create an index (i.e., record the storage address of the binary code stream for subsequent reading of the binary code stream) in a simple feature model database to store the binary code stream in the simple feature model database, that is, to store the slice file in the simple feature model database.

[0056] At this time, in this embodiment, the simple feature model data processing tool is used to process the slice file to generate a database operation command. The database operation command includes the binary code stream obtained by converting the slice file, specifically converting the spatial reference system information, zoom level, row and column numbers, and the content of the slice file into a binary code stream.

[0057] Optionally, after generating the database operation command, the OGC service publishing method based on the desktop geographic information system in this embodiment further includes: executing the database operation command, creating tables, inserting data, and creating indexes in the simple feature model database, and storing the binary code stream corresponding to the slice file in the simple feature model database, so as to store the slice file in the simple feature model database. Among them, the simple feature model database adopts the simple feature model.

[0058] (4) Data model conversion

[0059] At the database level, driven by the interoperability between the simple feature model and the generalized geoscience big data storage model, the write operation on the simple feature model is converted into an efficient write operation on the generalized geoscience big data storage model. Specifically, first create a generalized geoscience big data storage structure according to the user's needs at the levels of forest, tree, and branch, and then calculate the coordinate range of the slice file according to the zoom level and row and column numbers of the slice file. For the x coordinate, first map the longitude range from -180 to 180 degrees to the interval from 0 to 1, then perform a power-of-2 magnification according to the zoom level, and finally round down to obtain the x coordinate. For the y coordinate, first map the latitude range from -90 to 90 degrees to the interval from 0 to 1, then perform a power-of-2 magnification according to the zoom level, and finally round down to obtain the y coordinate. Write the calculated coordinate range of the slice file and the binary code stream of the slice file into the leaves at the end of the created generalized geoscience big data storage structure one by one to complete the storage and publishing of the map data.

[0060] In this embodiment, the forest can be a cluster of multiple projects, the tree can refer to a project, the branch can refer to a layer, and the leaves are used to store the slice files.

[0061] At this time, in this embodiment, according to the format of the generalized geoscience big data storage model, create a forest, trees, and branches according to the user's needs, that is, create the subordinate relationship and names of the forest, trees, and branches. The forest includes trees, the trees include branches, and the branches include leaves, and calculate the coordinate range of the slice file according to the zoom level and row and column numbers corresponding to the slice file, extract the binary code stream corresponding to the slice file from the database operation command, and store the binary code stream and the coordinate range in the leaves to store the slice file in the generalized geoscience big data storage model database. Among them, the generalized geoscience big data storage model database adopts the generalized geoscience big data storage model.

[0062] When there are multiple slice files, each slice file corresponds to a leaf of a branch. At this time, storing the binary code stream and the coordinate range in the leaves specifically includes: storing the binary code stream and the coordinate range of the slice file in the leaf corresponding to the slice file, and storing the binary code streams and coordinate ranges of different slice files in different leaves.

[0063] (5) Access address generation

[0064] Generate an OGC service access address according to the network address (including IP address, port number, etc.) of the ubiquitous geoscience big data storage model database and the storage location of the slice file in the ubiquitous geoscience big data storage model database. Users can access the slice file through this OGC service access address, thereby realizing the OGC service publishing based on the open-source desktop geographic information system.

[0065] At this time, in this embodiment, an OGC service access address is generated according to the storage location of the slice file in the ubiquitous geoscience big data storage model database to complete the OGC service publishing using the open-source desktop geographic information system.

[0066] Among them, generating an OGC service access address according to the storage location of the slice file in the ubiquitous geoscience big data storage model database specifically includes: generating an OGC service access address according to the network address of the ubiquitous geoscience big data storage model database and the storage location of the slice file in the ubiquitous geoscience big data storage model database.

[0067] This embodiment realizes the efficient publishing of geological maps as WMTS services in the open-source GIS system, solving the long-term technical gap in the industry. Through this embodiment, users of the geographic information system can innovatively realize the one-click publishing of geological maps as OGC services in the open-source GIS system. After the OGC service is successfully published, users can use the access link (i.e., the OGC service access address) to directly access the published OGC service through the network and quickly obtain the required geospatial data and geological maps. This instant data access method greatly improves the work efficiency and experience of users. Compared with the existing OGC service publishing technology, this embodiment does not require the assistance of external data formats or middleware, realizes seamless conversion of data formats at the database level, and cooperates with the ultra-high efficiency of the ubiquitous geoscience big data storage model for storage and publishing and sub-second response for tens of billions of data. The OGC service publishing speed of this embodiment is far superior to the existing technology, and the efficiency is significantly improved.

[0068] This application also provides an application scenario that applies the above OGC service publishing method based on the desktop geographic information system. Specifically, the OGC service publishing method based on the desktop geographic information system provided in this embodiment can be applied in the OGC service access scenario. The OGC service access scenario includes an OGC service publishing link and an access link. The OGC service publishing link is used to generate an OGC service access address, and the access link is used to enable users to access data through the OGC service access address. The OGC service publishing method based on the desktop geographic information system provided in this embodiment belongs to the OGC service publishing link.
