Embodiment Construction

[0059] Basic train of thought of the present invention is:

[0060] Construct a general "quintuple" framework for the capability representation model of earth observation sensors with observation capability as the core; develop a special element set for sensor capability representation; establish the mapping relationship between the sensor capability representation system and the sensor modeling language; The information model of the earth observation sensor for capability characterization, and based on the instantiation of the sensor modeling language, the information sharing of the earth observation sensor is completed. The invention realizes comprehensive and unified sharing of capability information of heterogeneous earth observation sensors, and lays a foundation for realizing integrated management of sensor resources, collaborative planning and other applications.

[0061] This embodiment takes the scanning type satellite sensor instance MODIS as an example to illustrate...

Abstract

The invention discloses a method for sharing information of an earth observation sensor based on a capability representation model. The method comprises steps of establishing a universal framework of the earth observation sensor capability representation model; establishing various earth observation sensor capability representation model special element sets; establishing mapping between the earth observation sensor capability representation model and sensor modeling language; establishing an earth observation sensor information model and completing instantiation of the model to share the information of the earth observation sensor. The method provides a firm capability information foundation for sharing and service of the earth observation sensor in a smart city framework, provides capability information with unified representation for planning and scheduling of the earth observation sensor, and provides consistent precision indices for capability measurement of the earth observation sensor.

Description

technical field [0001] The invention relates to the field of geographic space information sharing and interoperability in smart cities, in particular to a method for sharing information of earth observation sensors based on a capability representation model. Background technique [0002] Air-Space-Ground Integrated Earth Observation Network [1] It is a (geographic) space observation network that performs earth observation missions. It combines various earth observation sensors from different platforms (satellites, aviation, and ground stations) to form an overview of the four major spheres of the earth (lithosphere, hydrosphere, atmosphere, and biosphere) to achieve global, all-time, all-weather observations. The Earth Observation Network is a bridge between heterogeneous Earth observation systems, information models and decision-making. In the environment of the earth observation network, the capability information of the earth observation sensor, especially its observati...
