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.

New ISO/TC: Remote Sensing

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

• Radiometric reference targets for post-launch Cal/Val

• 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.
