Developing Standards for Building National Geological Map Database in a Systematic Way by Zuoqin Jiang, Information Center of The Ministry of Land and Resources, Beijing, China Building national or regional geological map databases is a complicated system engineering due to the following reasons: information presented in geological maps is complicated, information resources to build the databases includes both existing maps and maps from new geological mapping program, and data production is distributed in most cases. It makes standardisation of building NGMDB be complicated, which involves in standards in data content, data capture, data management, quality control and quality evaluation, data service and so on. These standards should be a standard family and related each other. In order to achieve purpose of data sharing in wider extent, it is necessary and very important to determine the content of the standardisation and relations among the family standards correctly, the principle applied to standard development and application. The International Standardisation Organisation (ISO) Technical Committee 211 for Geographic Information/Geomatics is engaged in preparing international standards in geographic information field. Reference Mode standard is included in the series of standards of ISO/TC211. It describes the environment within which the standardisation of geographic information takes place and the fundamental principles that will apply, adopts a model-based methods to analyse the standardisation requirement, and develops a architectural framework for the standardisation to direct the whole work. The paper try to use the method adopted by ISO/TC211 to address the content, relationship among the family standards and other issues of the standardisation of building national or regional geological map database.
