RESEARCH ON ESTABLISHING A MORE OPEN AND SYSTEMATIC NATIONAL GEO-INFORMATION STANDARD SYSTEM – TAKING CHINA’S GEO-INFORMATION STANDARD SYSTEM AS AN EXAMPLE

Abstract. Geo-information can be found, collected, released, shared, stored, combined and applied through geo-information standards. Building geo-information standard system is the basis for a country or organization to carry out the construction of geo-information standards. The excellent geo-information standard system can maximize the effectiveness of all geo-information standards in the system, so as to ensure that new geo-information sources and technical tools can be fully used. According to the analysis on the challenges of the construction of geo-information standards and standard systems in various countries by the author, most countries (including China) need to establish a more open and systematic national geo-information standard system and implement more flexible policies and measures for standards management. In this paper, the specific implementation measures proposed to improve China's geo-information standard system include 1) using policies to encourage the formulation, transformation and utilization of international standards 2) accelerating the top-level design of the construction of relevant information technology standard systems with geo-information as the core element, 3) filling the gap of standards construction by relevant group or enterprise according to the development requirements of geo-information industry, 4) evaluating and monitoring the important and concerned geo-information standards, etc. We think that the above measures will effectively improve overall openness and build better connection with the international standards, and ensure the scientific and forward-looking features during the construction and design of the standard system.
