[0002] Remote sensing and geographic information system (GIS) algorithms are crucial tools for processing and analyzing remote sensing and geospatial data to obtain necessary information and knowledge. Currently, a large number of remote sensing and GIS algorithms have been developed, with applications ranging from simple data transformation to complex domain application models. However, these remote sensing image processing algorithms require cumbersome and complex installation and configuration processes, and each has different usage methods, which greatly limits their application.

[0003] Network services are distributed, self-contained, and modular application components that can be described, published, found, and invoked within a network. They represent a standardized method for communication between different applications via a network. Currently, encapsulating remote sensing and geographic information algorithms into network services, including network services based on the Simple Object Access Protocol (SOAP) and geoprocessing network services (WPS) based on the Open Geospatial Information Consortium (OGC) standard, requires writing dedicated encapsulation code for each remote sensing and geographic information algorithm individually.

Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance.

The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0035] Please see Figure 1 The network service encapsulation method for remote sensing and geographic information algorithms provided in this application includes:

[0036] S10: Obtain the description information of remote sensing and geographic information algorithms, and convert the description information into a JSON format file.

[0037] In this embodiment, the descriptive information includes a functional description of the remote sensing and geographic information algorithm, the executable program name, and algorithm command-line parameters. The algorithm command-line parameters include input parameters, output parameters, and optional parameters. The descriptive information is stored as a JSON file according to a standard algorithm description format. Optionally, the descriptive information can be stored as a JSON file according to a custom algorithm description format.

[0038] S20: Deserialize the JSON format file to obtain the algorithm description POJO object.

[0039] A plain Java object is abbreviated as POJO (Plain Ordinary Java Object). POJO is used to emphasize that it is a plain Java object, not a special object, in contrast to special Java objects. Special objects primarily refer to Java objects that conform to specific Java object models, conventions, or frameworks, while a POJO is a Java object that is not restricted by anything other than the Java language specification. Deserialization refers to converting binary content back into a Java object. In this embodiment, the JSON format file is deserialized into an algorithmically described POJO object.

[0040] S30: Based on the preset algorithm command line parameter entity class template file, algorithm command line execution method template file, the algorithm description POJO object, and the template engine, generate the entity class code of the algorithm command line parameter and the Java execution code of the algorithm command line.

[0041] In this embodiment, a pre-defined algorithm command-line parameter entity class template file is established based on the definition method of Java class member variables and the generator design pattern to generate the entity class code for the algorithm command-line parameters. Specifically, the data types and variable names of the Java class member variables in the algorithm command-line parameter entity class template file are represented by specific placeholders, corresponding to the data types and names of the algorithm command-line parameters, respectively.

[0042] Based on the function definition conventions in Java, a pre-defined algorithm command-line execution method template file is created to generate the Java execution code for the algorithm command line. The template file uses placeholders to represent various descriptive information of the algorithm command line, including the executable program name and command-line parameter names.

[0043] This method utilizes a template engine to parse the entity class template file for algorithm command-line arguments and the template file for algorithm command-line execution methods. It takes the algorithm description POJO object as input data, uses its attribute names to match placeholders in the template, and replaces the placeholders with the corresponding attribute values. This automatically and in batches generates entity class code for algorithm command-line arguments and Java execution code for algorithm command lines.

[0044] S40: Generate network service encapsulation code based on the preset network service encapsulation interface template file, network service encapsulation implementation class template file, the algorithm description POJO object, and the template engine.

[0045] In this embodiment, based on the definition method of service interfaces, the definition method of interface implementation classes, and the usage method of service annotations in the network service development framework used, preset network service encapsulation interface template files and network service encapsulation implementation class template files are established. Different network service types (e.g., SOAP, OGC WPS, or REST) ​​and network service frameworks (e.g., Apache CXF and 52North WPS) have different definition methods for service interfaces and interface implementation classes; therefore, different template files must be established as needed. Placeholders are used in the template files to represent the name of the network service interface, the name of the method contained in the network service, the name of the parameter, and the data type, corresponding to the name of the encapsulated software, the name of the algorithm in the software, and the name and data type of the algorithm command-line parameters, respectively. The template engine parses the network service encapsulation interface template files and the network service encapsulation implementation class template files, taking the algorithm description POJO object as input data, and replacing the placeholders in the template files with the attribute values ​​of the corresponding attributes in the algorithm description POJO object, thereby automatically generating the network service encapsulation code.

[0046] S50: Copy the entity class code of the algorithm command line parameters, the Java execution code of the algorithm command line, and the network service encapsulation code to the preset network service skeleton project for compilation to generate a network service file.

[0047] In this embodiment, based on the basic project structure defined by the project management and automated build tool Apache Maven and the code organization structure of the network service development framework, a network service skeleton project is designed. Based on the examples and instructions in the network service skeleton project, automatically generated code is organized, and the dependent programs required for compiling and running the network service are compiled. Specifically, the entity class code of the automatically generated algorithm command-line parameters, the Java execution code of the algorithm command line, and the network service encapsulation code are copied to the corresponding skeleton project according to the network service type for compilation, generating a Java archive file (JAR format), i.e., the network service file, to be deployed.

[0048] S60: Deploy the network service file to the server to obtain the corresponding network service.

[0049] In this embodiment, according to the requirements of the remote sensing and geographic information algorithm and network service development framework, the runtime environment for the remote sensing and geographic information algorithms and network services is installed and configured. This includes installing a Java Virtual Machine or Python interpreter, installing the executable programs for the remote sensing and geographic information algorithms and their dependencies, installing a network service runtime container (such as Apache Tomcat), registering the network services to be published in the network service development framework, and configuring system environment variables. Then, the generated network service files are deployed to the network service runtime container to obtain the corresponding network services, and the network service runtime container is started to publish the network services.

[0050] Applying the embodiments of this application, the descriptive information of remote sensing and geographic information algorithms is obtained and converted into a JSON format file; the JSON format file is deserialized to obtain an algorithm description POJO object; based on a preset algorithm command line parameter entity class template file, an algorithm command line execution method template file, the algorithm description POJO object, and a template engine, entity class code for the algorithm command line parameters and Java execution code for the algorithm command line are generated; based on a preset network service encapsulation interface template file, a network service encapsulation implementation class template file, the algorithm description POJO object, and a template engine, network service encapsulation code is generated; the entity class code for the algorithm command line parameters, the Java execution code for the algorithm command line, and the network service encapsulation code are copied to a preset network service skeleton project for compilation to generate a network service file; the network service file is deployed to a server to obtain the corresponding network service. Based on the formatted algorithm description information, template engine, and network service skeleton project, this application embodiment constructs algorithm command line parameter entity class template files, algorithm command line execution method template files, network service encapsulation interface template files, and network service encapsulation implementation class template files. This allows remote sensing and geographic information algorithms to be quickly published as network services that can be called over the network, eliminating the need for manual writing of encapsulation code and improving the efficiency of algorithm network service encapsulation.

[0051] In an optional embodiment, please refer to Figure 2 Step S10 includes steps S101 to S102, as follows:

[0052] S101: Obtain descriptions of relevant remote sensing and geographic information algorithms from online documentation of remote sensing and geographic information analysis software, toolkits, and algorithm scripts using web crawlers;

[0053] S102: Convert the description information into a JSON format file according to the preset standardized algorithm description format.

[0054] A web crawler is a program or script that automatically retrieves information from the World Wide Web according to certain rules. In this embodiment, a web crawler automatically obtains the descriptive information of relevant remote sensing and geographic information algorithms from online documentation of remote sensing and geographic information analysis software, toolkits, and algorithm scripts, improving the efficiency of descriptive information retrieval. Simultaneously, the descriptive information is converted into a JSON format file according to a preset algorithm description standard format, making the descriptive information more standardized and structured, and easier for machines to read and recognize.

[0055] In an optional embodiment, please refer to Figure 3 Step S20 includes steps S201 to S204, as follows:

[0056] S201: Instantiate the JSON format file as a JSON object in Java;

[0057] S202: Obtain the property names of the JSON object, and the property values ​​corresponding to each property name in the JSON object;

[0058] S203: Get the attribute name of the preset algorithm description POJO class;

[0059] S204: If the attribute name of the preset algorithm description POJO class is the same as the attribute name of the JSON object, the preset algorithm description POJO class is instantiated into an algorithm description POJO object, and the attribute value corresponding to the attribute name in the JSON object that is the same as the preset algorithm description POJO class is assigned to the algorithm description POJO object.

[0060] In this embodiment, since the JSON format file has a large amount of data, the JSON format file is instantiated into a JSON object in Java, and then the JSON object is matched with the algorithm description POJO object, thereby converting the JSON format file into an algorithm description POJO object, saving memory resources and overhead, and improving response speed.

[0061] In an optional embodiment, please refer to Figure 4 Step S30 includes steps S301 to S304, as follows:

[0062] S301: The preset algorithm command line parameter entity class template file is parsed by the template engine, and the first template parameter in the preset algorithm command line parameter entity class template file is traversed.

[0063] S302: Obtain a first attribute name that matches the name of the first template parameter from the POJO object describing the algorithm, replace the first template parameter with the attribute value corresponding to the first attribute name, and generate the entity class code of the algorithm command line parameter;

[0064] S303: The preset algorithm command line execution method template file is parsed by the template engine, and the second template parameter in the preset algorithm command line execution method template file is traversed.

[0065] S304: Obtain the second attribute name that matches the name of the second template parameter from the POJO object described by the algorithm, replace the second template parameter with the attribute value corresponding to the second attribute name, and generate the Java execution code of the algorithm command line.

[0066] In this embodiment, the algorithm command-line parameter entity class template file includes several first template parameters, each with a name identical to one of the several attribute names representing the algorithm command-line parameter name in the algorithm description POJO object. The first template parameters serve as placeholders in the algorithm command-line parameter entity class template file. The algorithm command-line execution method template file includes several second template parameters, each with a name identical to several attribute names representing the algorithm command-line parameter name and one attribute name representing the algorithm name in the algorithm description POJO object. The second template parameters serve as placeholders in the algorithm command-line execution method template file.

[0067] The algorithm description POJO object obtains a first attribute name that matches the name of the first template parameter, replaces the first template parameter with the attribute value corresponding to the first attribute name, and obtains a second attribute name that matches the name of the second template parameter, replaces the second template parameter with the attribute value corresponding to the second attribute name, thereby automatically and quickly generating entity class code for algorithm command line parameters and Java execution code for algorithm command lines.

[0068] In an optional embodiment, please refer to Figure 5 Step S40 includes steps S401 to S402, as follows:

[0069] S401: The template engine parses the preset network service encapsulation interface template file and the preset network service encapsulation implementation class template file, and iterates through the third template parameter in the preset network service encapsulation interface template file and the fourth template parameter in the preset network service encapsulation implementation class template file.

[0070] S402: Obtain a third attribute name that matches the name of the third template parameter and a fourth attribute name that matches the name of the fourth template parameter from the POJO object described by the algorithm. Replace the third template parameter with the attribute value corresponding to the third attribute name and replace the fourth template parameter with the attribute value corresponding to the fourth attribute name to generate network service encapsulation code.

[0071] In this embodiment, the network service encapsulation interface template file includes several third template parameters, each with a name identical to one of the several attribute names representing the algorithm name in the algorithm description POJO object. These third template parameters serve as placeholders in the network service encapsulation interface template file. The network service encapsulation implementation class template file includes several fourth template parameters, each with a name identical to one of the several attribute names representing the algorithm name and command-line parameter names in the algorithm description POJO object. These fourth template parameters serve as placeholders in the network service encapsulation implementation class template file.

[0072] The algorithm describes a POJO object to obtain a third attribute name that matches the name of the third template parameter and a fourth attribute name that matches the name of the fourth template parameter. The attribute value corresponding to the third attribute name replaces the third template parameter, and the attribute value corresponding to the fourth attribute name replaces the fourth template parameter, thereby automatically and quickly generating network service encapsulation code.
