Problems solved by technology

[0004] The data interoperability specification has brought a new model for multi-source data integration, but this model has certain limitations in application: First, in order to truly realize the interoperability between data in various formats, each format needs to be The host software implements the data access interface according to a unified specification, which is not realistic for a certain period of time; second, when a software accesses the data format of other software, it is realized through the data server, a

Embodiment 1

[0025] Figure 1a It is a flow chart of data format conversion provided by Embodiment 1 of the present invention. The method can be executed by a data format conversion system, and specifically includes the following steps:

[0026] S110, the data format conversion system calls the local database, initializes the static resources in the local database, and obtains the source directory, the target directory, the format conversion template file and the filter condition.

[0027] Wherein, preferably, the data converted by the data format conversion system is spatial data.

[0028] Specifically, the static resource is the parameter of the configuration file in the data format conversion system and the local database resource, the source data is the initial data that the user needs to convert, the source directory is the directory where the source data is stored in the local database, and the format of the source data is converted The final data is used as the target data, and the ...

Embodiment 2

[0046] figure 2 The flow chart of data format conversion provided by Embodiment 2 of the present invention, the method can be executed by a data format conversion system, and specifically includes the following steps:

[0047] S210, the data format conversion system calls the local database, initializes the static resources in the local database, and obtains the source directory, the target directory, the format conversion template file, and the filtering conditions.

[0048] S220. The data format conversion system acquires at least one source file of a set type in the source directory.

[0049] S230. When the data format conversion system determines that the number of acquired source files exceeds the set threshold, read the source data in the source files and filter out the The source data for the filter.

[0050] Wherein, when the quantity of the source files obtained exceeds the set threshold, the data format conversion system adopts a thread pool or a multi-thread meth...

Embodiment 3

[0055] image 3 The flow chart of data format conversion provided by Embodiment 3 of the present invention, the method can be executed by a data format conversion system, and specifically includes the following steps:

[0056] S301. The data format conversion system calls a local database, initializes static resources in the local database, and obtains a source directory, a target directory, a format conversion template file, and filtering conditions.

[0057] S302. The data format conversion system acquires at least one source file of a set type in the source directory.

[0058] S303. The data format conversion system reads source data in the at least one source file.

[0059] S304. The data format conversion system stores the read source data into memory.

[0060] Specifically, the data format conversion system determines whether to enable the function of backing up source data by obtaining the parameters in the configuration file. The data format conversion system uses c...

Abstract

The invention discloses a data format conversion method and device. The method comprises the steps that a data format conversion system calls a local database, static resources in the local database are initialized, and a source directory, a target directory, a format conversion template file and a screening condition are acquired; the data format conversion system acquires at least one source file, of a set type, in the source directory; the data format conversion system reads source data in the at least one source file and screens out source data meeting the screening condition in the sourcedata; the data format conversion system calls the format conversion template file, data format conversion is conducted on the screened source data to generate target data, and the target data is stored into the target directory. According to the method, space data formats can be converted according to different systems and user requirements.

Description

technical field [0001] Embodiments of the present invention relate to data format conversion technologies, and in particular, to a data format conversion method and system. Background technique [0002] In the information society, a large amount of data from different sources is generated and stored in different places every moment. In the network environment, information should be distributed and processed in different software, and can be released in real time on the network. Different geographic information systems (Geographic Information System or Geo-Information system, GIS) systems have different understandings, description methods, conceptual models, data structures, and implementation methods for various spatio-temporal phenomena, and each has its own advantages and limitations. When implementing a new application function, first consider whether the existing data can be used, which involves the conversion of data. Some commercial GIS software manufacturers design ...
