The validation is an important guarantee of quality, reliability and applicability of Remote Sensing Products (RSPs), and is also the foundation to improve the RSPs accuracy, extend the application domain and strength the application ability. This paper introduced the progresses and lessons learned from a project titled by ‘key technology of remote sensing products validation and its experimental evaluation’ supported by Ministry of Science and Technology of China. The progresses included: ①Formulating a series of national standards composed of general methods for the validation of terrestrial quantative RSPs, field-site selection and instrumentation for land surface RSPs, and other 24 individual standards of remote sensing variables; ②Building integral technique process system of RSPs validation; ③Developing some key methods from optimized spatial sampling, upscaling to validation strategy; ④Obtaining the multi-scale satellite-airborne-ground synchronized observation and evaluating systematically the validation standard and techniques; ⑤Setting up national validation network for RSPs, exploring multi-mode allied observation experiment and forming the prototype and operation mechanism for the validation network.
