A Method for Segmentation, Coding and Access of Solar Wind Data in Large-Scale Solar-terrestrial Space

Abstract

The invention provides a solar wind data subdivision, encoding and access method of a large-scale solar-terrestrial space. The method comprises receiving original solar wind data output by a three-dimensional solar wind model; dividing the ecliptic plane or the meridian plane through a PDQG-R grid to automatically construct a PEQG-R grid with a corresponding resolution level, wherein the PDQG-R grid is radially and independently subdivided continuously on the basis of a PDQG grid when the radial subdivision levels are larger than the meridianal subdivision levels; encoding the PDQG-R grid, providing every subdivided subgrid with a unique identifier to form a one-to-one correspondence relation between the coordinates of the grid and the codes; computing the central point coordinate of every PDQG-R grid cell; according to the obtained central point coordinates of the PDQG-R grid cells, putting the original solar wind date into the PDQG-R grid, and when the original data are matched with one PDQG-R grid cell, assigning the attribute values of the original solar wind data to the central point of the PDQG-R grid cell.

Description

technical field [0001] The invention relates to the field of rapid organization of mass data of solar-terrestrial space physical fields, in particular to a method for segmenting, encoding and accessing solar wind data in large-scale solar-terrestrial space. Background technique [0002] The development of geographic information system, especially the development of digital earth technology, has enabled the research of earth science to have a powerful means of data organization and management. In the face of the rapid development of space science, with the massive growth of space detection data, how to organize and manage the detection data in the solar system, how to improve the efficiency of data access and data visualization, has become an urgent need for space scientists. The problems solved have important theoretical research significance and broad application prospects. [0003] Since there is no actual solar wind data of actual detection at present, what the present i...

AI Technical Summary

Problems solved by technology

[0006] To be applied to the subdivision of the solar wind, the polyhedral subdivision model and the adaptive grid model can be excluded. The coordinate calculation of the polyhedral model is relatively complicated, and the organization form is different from the existing surveying and mapping and remote sensing data, so it is difficult to integrate. The sub-model is a subdivision of a single scale, which is difficult to combine with multi-resolution
