In order to adapt to model change of the china civil spaceborne remote sensing from scientific experiments to the business service and promote the harmonious and sustainable and development of the space remote sensing

the center for national spaceborne demonstration was timely established in 2004

to explore

understand and solve the technical problems in the application requirements and space remote sensing system docking. For more than ten years

the demonstration center took the space remote sensing system as the research object

and systematically carried out the application-oriented space remote sensing scientific demonstration concepts

theory methods

technology engineering and application research. This paper is a systemic summary of the Demonstration Center team in space remote sensing scientific demonstration research and practice for a long time

which mainly introduces the content of four aspects

i.e. the preliminary cognition of scientific demonstration

the issue concerned to remote sensing demonstration

the theoretical system and model method set of remote sensing demonstration

and remote sensing demonstration practice of the application-oriented space remote sensing system. In this paper

a scientific demonstration definition of application-oriented space remote sensing is givenfor the first time and the range and content of demonstration is also detailed analyzed

and a 3D spatial structure of remote sensing demonstration scope composed of knowledge dimension

process dimension and logic dimension is proposed synchronously. As the social development has increasingly accelerated and the informatization level has increasingly enhanced

the whole space remote sensing data information chain is driven to develop towards larger-scale data stream

shorter response time cycle

more comprehensive data integration and higher data quality

so that the space remote sensing system will step in a development phase of new "intelligent remote sensing". Owe to the rapid development of our civil space in the past ten years

we have the opportunity to participate in the FY-3 satellite flying evaluation

multi-angle polarization multispectral remote sensing sensor demonstration

and HJ satellite applicationengineering demonstration

and have made the breakthrough invarioustheory methods. These research result have been applied to several demonstrations

such asthe2030 civil space development planning

the high resolution earth observation system

the national natural disaster spatial information infrastructure

the medium and long-term development of national civil space infrastructure

the China earth observation system planning（2030） and so on. Meanwhile

the theory system of remote sensingdemonstration has been established

which includes the information flow model

information feature model

information application model

information quantity analysis model

data engineering modelsystem structure model

system state magic model

system quality model

dynamic model of system development and system model of system capability. The theoretical system for remote sensing demonstration and corresponding model method set gradually formed through practice will comprehensively reflect the structure

state and development state of the space remote sensing system

and will be used for conducting investigation

analysis

evaluation

forecast

and carrying out practical exploration on the space remote sensing system.
