Multi-data center based natural resource geospatial data organization method and system

Abstract

The invention provides a multi-data center based natural resource geospatial data organization method and system. The method comprises a data type identification step, a feature class model establishment step, a relation class data model establishment step and an auxiliary information acquisition step. Firstly, the type of natural resource geospatial data is identified and data centers, a database, a data set and an auxiliary information set are established; secondly, according to the identified data type, establishing a feature class data integration organization model and establishing a relation class data model; and finally, according to the identified data type and a relation class data calculation result, acquiring auxiliary information and storing the auxiliary information in the auxiliary information set. According to the organization method provided by the invention, unification of different data types in a conception layer based on a plurality of data centers and integration organization management of different data types are realized; orderly data management and data tracking and backtracking are realized; and the application convenience and flexibility of the natural resource geospatial data are satisfied.

Description

technical field [0001] The invention relates to the technical field of natural resource geographic space data management, in particular to a multi-data center-based natural resource geographic spatial data organization method and system. Background technique [0002] The national natural resources and spatial geographic basic information database is one of the four basic national e-government information databases clearly proposed in the "National Informatization Leading Group's Guiding Opinions on my country's E-government Construction" (Zhongbanfa [2002] No. 17). The national e-government application and the public provide long-term, stable and standardized natural resources and spatial geographic basic information products and services, which have important reference value for the construction of cross-departmental e-government application systems, and at the same time improve the inter-departmental e-government cooperation mechanism It has positive exploration significance...

AI Technical Summary

Problems solved by technology

[0010] The present invention aims at the lack of traceability of data sources and whereabouts existing in the organization and management of natural resource geospatial data in the prior art, the different data types of multiple data centers are not unified at the conceptual level, and the collection of data information only records simple associations between data and other issues, a method for organizing natural resource geospatial data based on multiple data centers is proposed, which can realize the unification of different data types in multiple data centers at the conceptual level and the integrated organization and management of different data types, and realize the data At the same time of orderly management, it can also realize data tracking and backtracking, and effectively meet the convenience and flexibility of the application of natural resources geospatial data model
