Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] At present, the "7W" model has been introduced by many researchers in their academic research. For example, Li Yazi studied the data origin labeling mode and description model, and introduced the "7W" model of data origin content. In general, the "7W" model includes seven parts: who, when, where, how, which, what, and why. Its core is what, which records various events in the data life cycle to describe what happened to the data and the What is the data now; the other six items are all about what describes its information, describes the ownership of the data, when and where the processing process occurred, how the processing process is carried out, what elements and...

Abstract

The present invention provides a method and a system for extracting traceability information of a RINEX file. The method comprises: S1: extracting traceability information in a RINEX file designed inadvance by using a ''7W'' model; and S2: establishing a mapping relationship between the traceability information and the RINEX file. According to the method and the system for extracting traceabilityinformation of the RINEX file provided by the present invention, traceability information of a RINEX file creation link is designed according to the ''7W'' model, traceability information in the RINEX file is extracted, and the extracted traceability information is described in the ''7W'' model, so that according to the characteristics of the RINEX file, extraction of the traceability informationof the RINEX file can be effectively implemented, and a new idea is provided for traceability of the RINEX file; and in addition, by establishing a mapping relationship between the extracted traceability information and the RINEX file, efficient management and query of the traceability information can be implemented in a facilitated manner.

Description

technical field [0001] The present invention relates to the field of computer technology, more specifically, to a method and system for extracting traceability information of RINEX files. Background technique [0002] RINEX (Receiver Independent Exchange format, receiver-independent exchange format) is a data format commonly used in GPS measurement applications. This format was proposed by the Astronomy Institute of the University of Bern in Switzerland in 1989. After years of revision and improvement, it has now become a It is a standard data format in geodetic applications. Almost all survey GPS receiver manufacturers provide tools to convert their proprietary formats into RINEX format files. Almost all GPS data processing software can handle RINEX format files. [0003] RINEX data files are important data files in the field of geodesy, and their collection, processing, and release processes are extensive and distributed. These data are fused with data in other fields, and...
