Among them, the information sharing on the semantic level Especially difficult. Information ontology (hereinafter referred to as "ontology") technology provides effective technology in realizing semantic analysis, reasoning, and interoperability plan. At present, various fields related to geographic information, and even between different departments in the same field, have begun to build systems that meet their own needs. The requested information body. This reality makes it difficult to share information in distributed systems. The original intention of the domain to solve the problem of semantic interoperability is contradictory. The ontology model of geographic information is based on the understanding of concepts and data in the field of geographic information. Based on the semantic heterogeneity of data and systems, and the realization of the vision of semantic sharing and interoperability, the normative geographic information ontology model includes The construction principles and methods of the model and the formal expression of the ontology, etc., contribute to the integration and mapping mechanism between heterogeneous geographic information ontology The construction of, so as to provide the necessary common technical foundation for the realization of semantic level interoperability, and promote the integrated sharing and interoperability of geographic information, Expand the value-added areas of the geographic information industry. As an important part of geographic information, basic geographic information has a clear category and standardized classification system (GB/T 13923 "Classification and Code of Basic Geographic Information Elements"), and widely serve all walks of life. Therefore, this standard is based on this category. Geographic information semantic model specification. This standard analyzes the definitions, meanings and relationships of basic geographic information Common technical requirements such as ontology attributes (that is, conceptual attributes), sememes, and relational sets constructed by the formal ontology model are essential for the realization of basic geographic information. Information sharing and interoperability, it supports the formalization of basic geographic information concepts at the semantic level, and supports the semantic analysis and analysis of geographic information at the grammatical level. Reasoning, helping the design of database logical model and physical model at the data level. Fundamental Geographic Information Ontology Model1 ScopeThis standard specifies the ontology model of basic geographic information at the conceptual level, including the basic framework and structure of the ontology model of basic geographic information. Component elements, model construction criteria, model expression, etc. This standard applies to the construction of basic geographic information semantic model, the construction of general geographic information semantic model framework can be used by reference.2 Normative referencesThe following documents are indispensable for the application of this document.
