Embodiment Construction

[0022] Hereinafter, the technical solutions of the present invention will be further described with reference to the accompanying drawings.

[0023] like figure 1 As shown, a multi-source heterogeneous spatial data archiving method based on an adaptive metadata template includes the following steps:

[0024] (1) For a new data type, automatically parse and extract the tree structure information of the metadata file by uploading the metadata file;

[0025] (2) Obtain the element information of all leaf nodes according to the tree structure of the metadata file, configure the corresponding database fields and Chinese meaning information,

[0026] (3) Jointly extract element information and corresponding database fields, Chinese meaning information, classify and summarize the information, automatically generate a metadata parsing template and save it in the database; the metadata parsing template includes element path, database field, field type and Chinese meaning;

[0027] (...

Abstract

The invention discloses a multi-source heterogeneous spatial data filing method based on an adaptive metadata template, and belongs to the technical field of spatial data management. The method constructs a metadata parsing template, reads the template information from the database in real time during the process of data archiving and storage, and completes the dynamic parsing of the metadata cataloging information of spatial data. Start and recover concurrently, so that the software can run multi-threaded and efficiently; design the mechanism for data archiving task management, comprehensively consider the metadata analysis, normalization processing, cataloging and storage, archive storage and other processes of data archiving and storage, so as to realize data archiving and storage. Batch, high concurrency, and high reliability operation of library tasks. According to the characteristics of various types of spatial data, the invention customizes the generation of metadata analysis templates, avoids various problems in the existing data archiving process, and can realize dynamic self-adaptive, high-reliability and high-efficiency multi-source heterogeneous spatial data archiving.

Description

technical field [0001] The invention relates to the technical field of spatial data management, in particular to a multi-source heterogeneous spatial data filing method based on an adaptive metadata template, which can be applied to filing remote sensing data, ocean data, meteorological data and geographic information data. Background technique [0002] At present, satellite remote sensing technology has been widely used in military, civilian and commercial fields, and there are many satellite series. All kinds of spatial data need to be stored after being processed. After the data files are obtained, the metadata files (usually XML files) need to be parsed, and then the parsed metadata catalog information is stored in the database. Store the data files in the specified location according to the rules. [0003] At present, the mainstream data archiving methods are roughly divided into data analysis, metadata storage and data archiving and other steps. Among them, the metad...
