Abstract

Geo-spatial Information Engineering (GSIE) that is also called Digital Engineering is the information engineering on the basis of the integration of Remote Sensing, Geographic Information System and other information technologies. The information standard that includes standard architecture, rules, criterion and policy is an important component of GSIE. The author studies the concept, object and aim of Standard of GSIE, discusses the planning, architecture and reference model and how to develop the system of Specialized Standard of GSIE. The Standard of GSIE is the uniform regulation of the data resources, information flow, information construction and management of GSIE. The object of Standardization of GSIE is a mass of repeat data resources and disposal businesses. The aim of Standard of GSIE includes: building a set of application-oriented standard framework, depicting the Geo-spatial information basic semantic and structure; building the related models; regulating the geo-spatial service contents and geo-spatial processing service to realize the inter-operation. The technology approach of Standard of GSIE is: ascertaining the discussion domain-building the concept schema-realizing the operation. The architecture of Standard of GSIE makes up of three parts: Direction Standard, Basic Standard and Specialized Standard. The reference model of Standard of GSIE describes the overall aim, basic concept, architecture, framework, relations among all kinds of standards. The architecture is the wholeness that is arranged according the inter-relation. The representation is the s diagrams of standard system. The author expands the Basic Standard to fulfill the practice requirement by means of profile method, builds the geo-spatial information domain and reference structure, develops the information standard system of the level of geo-spatial dataset and information service
