Problems solved by technology

[0008] 1. Spatial expression and time expression are relatively separated, GIS technology is obviously weak in time-domain feature changes, and the dynamic expression required by digital twins is difficult to achieve well
[0009] 2. GIS technology emphasizes layer format expression, and data fusion between layers is difficult
Multi-layer overlay is difficult to achieve
[0010] 3. The tools of GIS technology are too strong, and the threshold for users is relatively high, so it is difficult to meet the needs of mass data analysis in the era of big data
[0011] Although Microsoft's Excel product is a common tool for data analysis, its tables do not have spatiotemporal semantic connotations, and cannot be directly and effectively used for spatiotemporal big data analysis and utilization

Abstract

The invention relates to the technical field of information, and discloses a chart integrated space-time grid data table structure. The structure comprises a basic table, wherein a header of the basic table comprises space codes, time codes, and object names, attribute types, attribute values, and grid area / volumes corresponding to the space codes and the time codes. The invention further discloses a transformation method of the chart integrated space-time grid data table structure. The method is characterized in that transformation operation is carried out on the space codes and / or the time codes in the basic table, the transformed space codes and / or the time codes and the corresponding attribute values are arranged in the same advanced table, and the transformation method has light-weight data visualization capacity. According to the embodiment of the invention, GIS layer type expression and operation are simplified into an Excel data table, and the problem of cross-layer data fusion is solved; the table data is very suitable for the introduction of technologies such as machine learning, so that innovative basic support is provided for analysis and utilization of space-time big data in the whole society.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a chart-integrated space-time grid data table structure and a transformation method thereof. Background technique [0002] Space is an objective form of material existence opposite to time, but the two are inseparable. [0003] The expression of space usually adopts GIS technology, GIS is geographic information system. It is a comprehensive subject that combines geography and cartography as well as remote sensing and computer science, and has been widely used in different fields. GIS data represents the objective objects of the real world in the form of digital data. Objects in the real world can be divided into two abstract concepts: discrete objects (such as houses) and continuous objects (such as rainfall or altitude). These two abstractions mainly store data in GIS system in two ways: raster (grid) and vector. [0004] Time is a parameter used by human beings to desc...
