Integrated and space-time big data and geographic information public service cloud platform

Abstract

The invention discloses an integrated space-time big data and geographic information public service cloud platform. The platform comprises a spatio-temporal information big data subsystem and a platform operation and maintenance management subsystem. The spatio-temporal information big data subsystem comprises a production module, an arrangement module and a management module, the production module manages basic surveying and mapping data storage, basic surveying and mapping data production and geographic space framework data standard establishment, and basic surveying and mapping data comprises DLG data, DOM / DEM data, thematic data and place name address data; the arrangement module preprocesses the basic surveying and mapping data; the management module checks and modifies the processeddata; and the platform operation and maintenance management subsystem manages system services, infrastructures and log management. According to the platform, a private cloud service renting mode is adopted, so that rapid establishment of the platform based on the same network is realized, the construction capital and technical requirements of the platform are reduced, and sharing of geographic data service resources among different users is realized.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to an integrated spatio-temporal big data and geographic information public service cloud platform. Background technique [0002] With the successive completion of the "Digital City Geospatial Framework" and the gradual deepening and promotion of digital cities, various departments are also facing a series of problems such as high technical thresholds, heavy operation and maintenance pressure, difficult application expansion, and large investment. In the transition from digital city to smart city construction, there are practical problems in the application of digital city construction: [0003] 1. Digital city construction lacks top-level design; [0004] 2. The problem that the information system cannot share information is still prominent; [0005] 3. The urban management system cannot adapt to the construction of information technology, and technical and management p...

AI Technical Summary

Problems solved by technology

[0003] 1. Digital city construction lacks top-level design;

[0004] 2. The problem that the information system cannot share information is still outstanding;

[0005] 3. The urban management system cannot adapt to the construction of information technology, and technical and management personnel are still insufficient;

[0006] 4. Lack of evaluation system for digital city construction

[0011] But there are few connections and sharing is not strong

The business information systems of various departments have not formed a network, and the phenomenon of information heterogeneity is prominent. The systems cannot be interconnected, interoperable and interoperable. There is a lack of unified planning, and it is impossible to coordinate operations and solve major and complex problems.

[0012] (3) The achievement standards of digital cities are not uniform, and the standardization needs to be improved

[0013] Different departments or industries have different classifications, gradings and interpretations of the same thing, and the representation methods are not uniform. The non-uniform standards directly lead to a low degree of automation in data exchange, and it is impossible to provide consistent geospatial data services, especially in the understanding of land use classification. The difference is very unfavorable to urban planning and management

[0014] (4) The method of information acquisition is relatively single, and lacks dynamic updates

[0015] In the era of explosive growth of information, information data is the soul of the system, lack of updates will not only affect the authenticity of the perceived city, but also greatly reduce the practicability of the system

[0016] (5) The legal system is not perfect, the degree of information openness is not high, and the operating mechanism needs to be further improved

[0018] (6) Unclear understanding of digitalization, networking, intelligence and their interrelationships in the process of urban informatization construction, lack of scientific planning and top-level design, and many difficulties in the process of transforming digital cities into smart cities
