Embodiment

[0062] Taking the particle density data output by the solar wind model at a certain moment as an example, the steps of three-dimensional volume subdivision, encoding, and retrieval are described in detail below.

[0063] Step 101) receiving the data of the three-dimensional solar wind model;

[0064] Step 102) Divide the sun-terrestrial space with SDOG-R grids, and set the LOD levels to be divided according to requirements, thereby automatically constructing SDOG-R grids (Sphere Degenerated-Octree Grid-Radius) with corresponding resolution levels. The SDOG-R grid is described as:

[0065] The SDOG-R grid model is a radially subdivided spherical degenerate octree grid. The specific subdivision steps are:

[0066] 1. Divide the entire sphere twice in longitude and once in latitude to form 8 octants;

[0067] 2. The first division of the octant. First, divide the radial line equally, cut the octant with a sphere whose radius is half of the original radius, divide the octant in...

Abstract

The invention provides a large-scale solar-terrestrial space solar wind data subdivision, encoding and access method. The method comprises the steps of receiving original solar wind data output by a three-dimensional solar wind model; subdividing SDOG-R grids for a solar-terrestrial space, setting subdivision LOD level according to the demands, and accordingly automatically establishing corresponding resolution-level SDOG-R grids, wherein the SDOG-R grids are radially-subdivided sphere degeneration octree grids; encoding the SDOG-R grids, wherein an encoding mode is that a unique identification is given to each subdivided SDOG-R sub-grid to enable coordinates of the grids and endowed unique identifications to for one-to-one correspondence incidence relation; calculating a coordinate position corresponding to a central point of each SDOG-R grid; putting the original solar wind data into the SDOG-R grids; retrieving the original solar wind data based on grid codes, namely the SDOG-R grid codes, decoding and meanwhile looking for grid positions corresponding to the codes and extracting contents placed in the grids.

Description

technical field [0001] The present invention relates to the field of rapid organization of massive data of solar-terrestrial space physical fields, that is, the present invention provides 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 detection of solar wind data, th...
