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. www. aoe. cas. cn 10

Find and Suggestions l WGCV not only output research result and built CV capacity but also definitely produce procedures, references, guidelines etc. to normalize the CV missions l Those procedures, references and guidelines could be formalized a Standard to benefit all EO sectors as well as its marketing activities. l. QA 4 EO and Data sharing both need the standard for quality control and data or product exchange. l. CEOS is just in the right position to lead EO or RS standardization work Suggestion l 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 l WGCV involves the standardization issue into its current CV actions www. aoe. cas. cn 11
