Some technical standards were published in China.
The standardization was in elementary stage. The formulation of standards was dispersive and lack of a systematic planning and management.
National Technical Committee 327 on Remote Sensing of Standardization Administration of China (SAC/TC327) was established in March 2008 and authorized by SAC.

A new ISO/TC be required to support the development of remote sensing.
The work scope of existing TC can not cover the whole remote sensing.
Lack of standards: • from signal to data, including acquiring,
receiving, archiving, pre-processing, etc.
• from data to product, such as information extraction, calibration & validation.
• from scientific research to market, for instance, industrial applications, management & service, etc..

Part Ⅳ: Suggestions for Standardization of RS
Scope
• Standardization in the field of RS technology, particularly EO data quality assurance which will include terminology, methods, instruments and systems for the sensor calibration & performance assessment, data processing & quality evaluation, product validation, and data management & services.

WG 2: Data evaluation &validation
WG 3: Cal/Val data acquiring & management
• Imaging quality assessment - optical sensor – Part 1: radiometric quality • Imaging quality assessment - optical sensor – Part 2: geometric quality • Imaging quality assessment - optical sensor – Part 3: spectral quality

• Data record requirements on land surface parameters for Cal/Val
• Requirements on spectrum measurement for Cal/Val
• Requirements on location and equipment of radiometric calibration site
• Data quality evaluation and its rating scale for optical RS
• Guidelines for validation of RS data & product

We are in the internal process to provide a proposal to
ISO to establish a new ISO/TC as mentioned above
through SAC, the representation of China in ISO.
We really hope to have support from all of you.
Any comments regarding to the issue are very welcome.
