Space-time and element unified coding data management method

Abstract

The invention discloses a space-time and element unified coding data management method, which comprises the following steps of: performing spatial feature extraction on input data, and performing spatial coding to establish a unit conforming to spatial features of the input data; carrying out time feature extraction on the input data, and carrying out time coding to establish a unit conforming tothe time feature; element feature extraction is carried out on the input data, element coding is carried out, and a unit meeting element features is established; and constructing a multi-level index mechanism for retrieval. According to the invention, space-time and element information is combined; according to the method, a set of coding model with characteristic change attenuation is constructed, a geographic space, large-span time and multi-factor data management method is effectively realized, natural association and mining analysis of data are realized based on the method, and meanwhile,the problems of difficult storage, difficult management and difficult retrieval of massive data are effectively solved by a multi-level index mechanism.

Description

technical field [0001] The invention specifically relates to a data management method for unified encoding of space-time and elements. Background technique [0002] At present, various information systems have access to a large amount of data. In order to dig out deep connotations from these massive data more accurately, more completely, faster, and more precisely, and realize the transformation from data to information and knowledge, it is necessary to follow the big data The idea of ​​data governance and data organization. [0003] At present, the data management mechanism considering geographic information is attracting attention from all parties, and a lot of effort has been invested in theoretical innovation and technological innovation, but it is mainly focused on the planar geographic grid, or on the basis of the platform grid. This method is more suitable for solving the storage and analysis of near-earth or near-space data, but the details are as follows: figure 1...

[0003] At present, the data management mechanism considering geographic information is attracting attention from all parties, and a lot of effort has been invested in theoretical innovation and technological innovation, but it is mainly focused on the planar geographic grid, or on the basis of the platform grid. This method is more suitable for solving the storage and analysis of near-earth or near-space data, but the details are as follows: figure 1 As shown, due to the existence of the earth's surface curvature and the irregularity of the earth's shape, this method will cause deformation in the far-space area and cannot truly reflect the spatial characteristics such as area and volume, which will lead to insufficient data storage, management or analysis , or even deviation or error

In addition, current research mainly focuses on geospatial coding, and the consideration of time has not yet formed a complete solution, which limits the application space of this method.

At the same time, the current research results mainly focus on theoretical research, more on the formulation of standards, and the technical practice is not deep enough
