Natural resource element level product manufacturing method and system

Abstract

The invention relates to a natural resource element level product manufacturing method. The method comprises an original product manufacture and management step, a product element unit manufacture and management step and a new thematic map product combination and output step. Firstly, a parameterized thematic map template library is manufactured, collected natural resource data are loaded to generate thematic map original products automatically, and the generated thematic map original products are stored and managed unifiedly; product element units are obtained, subjected to normalized data processing and normalized encoding and unifiedly stored and managed in a file management manner; association retrieval of target product names of the unifiedly stored and managed product element units is established on the basis of an engine retrieval technique, and the required product element units generate and output new thematic map products after combined. With the adoption of the method, automation and parameterization of GIS (geographic information system) thematic map product manufacture are realized, and the manufacture effect, precision and efficiency of the natural resource element level products are greatly improved.

Description

technical field [0001] The present invention relates to the technical field of natural resource geospatial data products, in particular to a method and system for producing natural resource element-level products. 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. The layout of the bas...
