Exchange service and routing process management of basic data and shared data are the basis of a forestry data sharing service platform, and comprise the following steps: static exchange data, dynamic exchange data, graphic data, tables, statistical data and other attribute data. The interface implementation among the subsystems can realize data sharing and transmission operation among the subsystems according to the pre-made specifications and standards. When the forestry data sharing service platform is accessed, a system structure is designed according to system integration requirements, and various data interfaces follow system integration specifications.
In order to satisfy the application layer exchange and the data layer exchange, the data supplier and demander, that is, each subsystem needs to have the functions of connection and interface adaptation of the application layer and the data layer, and the function of conversion of the data format. In order to ensure the correct transmission and transmission performance of data, each subsystem also needs to have transmission management functions, including functions of transmission protocol management and control, transmission process control, data transmission encryption, compression, network fault detection, connection sharing and the like.

Moreover, timing and real-time strategies need to be supported, functions such as timeout control management and the like need to be supported, and a forestry data sharing service platform must have functions of session strategies, session control and management.
In order to exchange data according to standards and deployed routing rules, the forestry data sharing service platform must have functions of data routing, data template management, data analysis, data conversion and the like. Meanwhile, the forestry data sharing service platform also needs to provide service management functions, including functions of operation management, deployment management, service management, system log and the like. In order to be combined with the security platform, an interface design function with the security platform is also necessary.
Fig. 1 is a schematic flow chart of a data sharing method based on a forestry data sharing service platform according to an embodiment of the present invention. The method is applied to a forestry data sharing service platform. The method specifically comprises the following steps.
S110: acquiring initial forestry data from a subsystem establishing a connection relation with a forestry data sharing service platform; the initial forestry data includes: public basic data of forestry, forestry special topic data, forestry integrated management data.
In the embodiment of the invention, the forestry data sharing service platform can adopt a service-oriented architecture and utilize an advanced database technology and a computer network technology to realize multi-source spatial data integration and sharing in a heterogeneous platform environment. The platform provides an excellent data sharing exchange platform for avoiding repeated construction, saving cost, eliminating information islands, promoting data sharing and cooperative office among departments of ecological committees and promoting government informatization construction.
Wherein, forestry data sharing service platform is based on unified basic geospatial reference and high-resolution orthographic remote sensing image data, integrates all kinds of basic data of stack forestry resource, includes: and establishing a core database construction standard by using forestry basic data, forestry special data, forestry comprehensive management data and the like.
S120: and according to the locally stored data dictionary, performing data conversion on the initial forestry data to obtain standard forestry data, and storing the standard forestry data to a database.
In the embodiment of the invention, the forestry data sharing service platform can maintain a standard data registration center for data sharing, and provide shared information for each access system and each application system in a standardized data mode. Specifically, the forestry data sharing service platform may maintain a data dictionary for completing translation of the nonstandard data and the standard data, thereby providing standardized forestry data to the shared standard database.
For special data information in a single function field, the forestry data sharing service platform provides a direct exchange way among subsystems, and the application requirements of specific functions are met. Moreover, the forestry data sharing service platform is provided with a special maintenance and management mechanism which respectively carries out maintenance management such as addition, update and the like on a data dictionary and a database of the system so as to meet the requirements of new subsystem access and system development.
In one implementation, when performing data conversion on the initial forestry data, the initial forestry data can be input into a data converter, and the data converter converts the type and value of the initial forestry data according to a preset conversion rule based on a data dictionary to obtain standard forestry data; or performing data conversion on the initial forestry data based on the spatial data conversion standard according to a locally stored data dictionary to obtain standard forestry data.
The data sharing mode comprises a data format conversion mode, a data direct access mode and a data interoperation mode.
Data format conversion is to design a data conversion tool to convert data in one format into data in another format. The implementation of this data sharing can be divided into two cases: converted by a data converter and converted based on spatial data conversion criteria.
The data converter is an internal data model, and obtains the specified data model and value by converting the input data type and value according to the conversion rule. This conversion occurs between two data files and the data conversion between the systems is unidirectional, i.e. the converted data may not be usable in previous systems. For example, the ArcToolbox module in the ArcGIS software has a data conversion function of converting the data format in the manner of an application data converter.
The transformation criteria is a set of rules that are well followed and comprehensive by everyone. Through the intermediate bridge, data in all different systems are converted into a uniform standard format for being called by other systems. The transformation standard for spatial data must be able to represent a range of attributes and relationships of real-world entities, while it must provide a transformation mechanism to ensure that the description structure for these attributes and relationships does not change and can be properly invoked by the recipient.
Data format conversion is a main method for realizing data sharing at present, and other data formats are subjected to format conversion through a special data conversion program and are copied into a database or a file of the current system. These formats have various features, but because of lack of a uniform description method for the spatial object, the data models adopted when the spatial object is described in different data formats are different, so that the information of the source data cannot be completely and accurately expressed after conversion, and the information of the source data is partially lost during conversion.
The direct data access means that direct access to other software data formats is realized in one piece of software, and a user can access multiple data formats by using a single piece of software. The direct data access not only avoids the complex data conversion, but also does not require a user to have host software of a certain software to access the data format of the software in one software, and even does not need to run the software. The direct data access provides a more economical and practical multi-source data sharing mode. The direct data access is also based on the full knowledge of the data format to be accessed, if the data format to be accessed is not public, the format cannot be decoded, and the decoding is ensured to be completely correct, so that the data sharing can be really realized with the host software of the format. If the data format of the host software changes, each piece of data integration software has to research the data format of the host software again to provide an upgraded version, and the data format of the host software is not declared to the outside when changing, so that other pieces of data integration software have to have hysteresis on data processing based on the data format of the software.
Interoperation refers to two or more entities in a heterogeneous environment that can communicate and cooperate with each other to accomplish a particular task, despite differences in the language in which they are implemented, the environment in which they are executed, and the underlying model. These entities include applications, objects, system operating environments, and the like. Interoperability is a free combination and matching of the components of an information system, rather than a compromise of overall success. The data conversion method is only from the data point of view, and is the integration of data, and does not consider the data processing aspect. So that true interoperation cannot be achieved. Interoperation occurs under heterogeneous databases and distributed computing. For the system, the system can acquire and process the messages of the other side more safely; for the user, the user can conveniently inquire the required information and can conveniently use data of different types and formats; for information managers, they can manage information well, serve users, and provide resources to users adequately. The data interoperation is free information exchange and cooperative running of geographic information processing software. To achieve interoperation of data, it is implemented through a common interface. An interface is a protocol, which is a unified standard that is well followed and agreed upon. In the interface, not only the data format and the data processing are considered, but also a protocol to be adopted for the data processing is provided, and the systems are mutually connected through a common interface, and the internal data structure and the data processing of the systems can be allowed to be mutually different.
Data interoperability emphasizes the integrated operation of software systems with different data structures and data formats, and compared to data transformation, interoperability considers not only data, but also processing, which is the inter-working between different systems at a higher level. It is not only the integration of data, but also the integration of processes.
S130: when a data acquisition request sent by a target subsystem is received, determining whether the target subsystem has access authority of a grade corresponding to the service type according to the service type corresponding to the data acquisition request and the verification information of the target subsystem.
In the embodiment of the invention, as the forestry data files exchanged among the subsystems contain a lot of sensitive information, the safety requirements in the data exchange process are very strict. The forestry data sharing service platform must provide a security mechanism to ensure the integrity of the data exchange information and the confidentiality of the data exchange information. The forestry data sharing service platform must be effectively combined with the security authentication platform, and the exchange information content can be protected from interception or illegal modification through the security authentication platform and the forestry data sharing service platform.
Specifically, the forestry data sharing service platform may set different permissions for different subsystems, that is, different subsystems may be allowed to acquire data corresponding to different service types.
For example, for each subsystem, security authentication may be performed by:
and (4) safety authentication management: the data center applies single sign-on authentication;
and (3) access authority control: the authority control can be carried out on the operation in the business process and the access to the data and the resources;
