A full spatial information expression method and a full spatial information system

Abstract

The invention discloses a whole space information expression method and a whole space information system. The method includes following steps: statically describing whole space information which includes position coordinates (x, y, z) and natural attributed information of a space entity in physical world and network virtual world; adding time attribute, and adding a time identity for the space entity in a static state to realize dynamic description of the whole space information; providing place name address identity and address grid coding identity under uniform time-space standards to realize correlation and integration of different space entities based on geographic space position or range. The system comprises a space entity description module, a time identity module and a place name address description module. The whole space information expression method is used for realizing dynamic description and combining communication of all space entities having position information in the virtual world and realizing whole space information expression of geographic position, natural attribute and time-space attribute of the space entities and thematic data under the uniform time-space standards.

Description

technical field [0001] The invention relates to the technical field of spatial expression of surveying and mapping geographic information, in particular to a full-spatial information expression method and a full-spatial information system. Background technique [0002] In recent years, with the development and popularization of information and communication technology, many achievements have been made in the construction of digital cities in China, and the construction of smart cities is the current upsurge. The development and construction of smart cities has brought unprecedented opportunities and challenges to my country's urban planning and management. In the field of surveying and mapping geographic information, the basic space-time concept of traditional urban planning and management objects has developed to a new stage. [0003] There are two challenges in the new stage: First, in terms of time, the current time interval is greatly shortened, and the demand for real-t...

Second, from the perspective of space, the accuracy of spatial data is getting higher and higher, which greatly improves the accuracy of urban management. The application of big data has improved the efficiency and accuracy of data utilization. etc.) have established unique geographic unit division standards based on their own business foundations, resulting in inconsistencies in the basic spatial units of multi-source spatial data, and the lack of a unified and standard geographic reference system, making it difficult to integrate data
