  1. Standardization of Remote SensingTechnology in China Chuan-rong LI Academy of Opto-Electronics (AOE), Chinese Academy of Sciences (CAS) National Remote Sensing Center of China(NRSCC) Oct. 24-27, 2012

  2. Outline Standardization of RS Technology In China 1 International Situation in Standardization of RS Technology 2 Finding and Suggestion 3

  3. Standardization of Remote Sensing Technology In China • Effort and Progress made in China on RS Standization: • National Technical Committee 327 on Remote Sensing of Standardization Administration of China (SAC/TC 327) was established on March 2008. • Academy of Opto-Electronics(AOE) is the secretariat of the committee to facilitate the implementation. • SAC/TC 327 Committee has close cooperation with National Remote Sensing Center of China (NRSCC).

  4. Website of SAC/TC 327 Main modules: • News & Information • Reports & achievement • Standard development & revision • Knowledge of standardi-zation • About SAC/TC 327 English version of the website is to be built. http://www.rsstandard.cn

  10. International Situation in Standardization of Remote Sensing Technology International Organization for Standardization (ISO) In ISO’s over 220 TCs, the following eight TCs have certain correlation with remote sensing technology : ISO/TC 20 "Aircraft and space vehicles" ISO/TC 42 "Photography" ISO/TC 130 "Graphic technology" ISO/TC 146 "Air quality" ISO/TC 147 "Water quality" ISO/TC 172 "Optics and photonics" ISO/TC 190 "Soil quality" ISO/TC 211 "Geographic information/Geomatics" / WG 06 "Imagery" ≠ Remote Sensing A new ISO/TC is required to support the development of RS standards.

  11. Find and Suggestions • WGCV not only output research result and built CV capacity but also definitely produce procedures, references, guidelines etc. to normalize the CV missions • Those procedures, references and guidelines could be formalized a Standard to benefit all EO sectors as well as its marketing activities. • QA4EO and Data sharing both need the standard for quality control and data or product exchange. • CEOS is just in the right position to lead EO or RS standardization work Suggestion • CEOS takes concern on RS Standardization issue and strength the liaison action to ISO to get support in creation of a new ISO/TC on Remote Sensing technology domain • WGCV involves the standardization issue into its current CV actions
